It was about time I made a comprehensive guide on how to increase testosterone levels.

After hundreds of specific posts about what affects your natural testosterone production and hormonal health and how to increase testosterone naturally, I had yet to compile it all into one easily accessible article that covered all the basics.

The goal of this article is to get you closer to knowing most of what you need to know in order to optimize your natural testosterone production. It links out to hundreds of other more specific posts about various topics discussed, while it also references hundreds of different studies.

A big resource sort of.


Primer: Testosterone is the principal male sex hormone, responsible of most of the male characteristics.

Your body produces it when the hypothalamus in your brain sends out bursts of something called GnRH (gonadotropin releasing hormone), which then travels to the other brain gland called pituitary gland, where the GnRH stimulates the release of two hormones called follicle stimulating hormone (FSH) and luteinizing hormone (LH), these are the gonadotropins.

The gonadotropins (LH and FSH) then make their way down to the testicles via your spine, and once they reach their destination FSH stimulates sperm production, whereas LH stimulates the testicular leydig cells to produce testosterone from a well known precursor; cholesterol.

After the testosterone is made and done, it travels around in your bloodstream. Some of it remains bio-available in circulation as free-testosterone, some of it make its way into its target receptors around the body (androgen receptors), while some of it gets bound and rendered partially inactive by two carrier proteins called albumin and SHBG.

Small parts of your available testosterone will also metabolize to estrogen (the principal female hormone) via an enzyme called aromatase and dihydrotestosterone or DHT (more potent male hormone) via an enzyme called 5-a reductase.

All of the moving pieces that affect this synthesis, can be affected naturally by training, nutrition, lifestyle, and supplementation.

I’m sure you have seen the endless list of the benefits of optimal testosterone levels, which include (but are not limited to):


…Since testosterone is literally the hormone that makes man a man, it’s safe to expect increased manly qualities in nearly every area of your life after increased testosterone levels. Not everything is controlled by testosterone obviously, but if you start looking at the studies, it’s pretty clear that from womb to tomb, this one hormone determines A LOT in a guy.

This guide on learning how to increase testosterone levels is broken into 4 big sections; lifestyle, nutrition, training, and supplementation.

The four sections hide inside multiple topics from sleep, to macronutrient splits, to testicular health, all the way into neuromuscular training, hypoxia, sleep, sex, walking…

…Without further ado, let’s get to the ultimate guide on how to increase testosterone levels:


1. Sleep Deep and Sleep a Lot

sleep and testosterone levelsWhether you choose to sleep four hours or eight hours, can mean a difference similar to night and day in your T production.

Partial sleep restriction lasting one-week (5h/night) in a laboratory setting has been shown to decrease overall 24-hour testosterone levels in healthy young men by ~15%.

On a study by Penev et al. the men who slept for ~4 hours had an average of 200-300 ng/dL testosterone levels in serum, whereas the guys who slept for ~8 hours had levels closer to 500-700 ng/dL.

A study from Gov et al. showed similar results. On 531 Chinese men, increased sleep time was highly correlated with higher total and -free testosterone levels. The researchers also calculated that each extra hour of sleep led to about 15% more testosterone.

2. Be Lean and Have Some Muscle Mass

get lean and have low body fat percentage for more natural testosteroneYou definitely don’t have to be light to increase your testosterone levels naturally, but you should be LEAN.

More specifically, your body fat percentage should be relatively low (something between 8-14%), if your goal is to get more T oozing through your veins.

Generally speaking – though there are some rare exceptions – the higher the fat percentage, the lower the testosterone (study, study, study, study). So in retrospect, the leaner you are, the more likely you are to have more testosterone rushing in your bloodstream. Increased amount of muscle mass also positively correlates with serum testosterone levels, so if you burn the fat and build the muscle, you’ll not only look shredded, but you can improve your hormonal health too.

The THOR Testosterone Training program does an excellent job at this, since it was designed specifically to boost testosterone and optimize hormones through specific training protocols.

Why does being fat often leads to low testosterone levels? The full answer is likely much more complex than this, but what we do know is that increased fat-mass leads to increased aromatase enzyme activity, which in turn leads to more testosterone being converted to estrogen. Also, increased oxidative stress, metabolic syndrome, and poor insulin-sensitivity are some other major-players in obesity related low-T.

Good news is that you can easily increase testosterone naturally just by losing weight, in particular losing the fat-mass, not muscle. Though it’s worth mentioning that there is a limit to your leanness where it start to negatively impact testosterone production; going below ~8% body fat starts to decrease thyroid activity, and because of that you’ll eventually have to start cutting your caloric intake too much, and both of those things will start zapping the life out of your androgens.

 The weight-loss industry is chock-full of some major league bullshit. This guide should help you in getting to know everything there is to know about losing fat in a sane muscle-preserving way. 


3. Stress Less

stress and testosterone levels in menMore easily said than done huh? Well it doesn’t change the fact that stress more or less kills testosterone levels.

This happens because chronic stress results in chronically elevated cortisol levels – and cortisol being the body’s principal stress hormone – is a catabolic hormone that among many other things; suppresses testosterone levels.

…No don’t get me wrong here, we all need some cortisol. It gets us up in the morning and allows us as a species to walk with 2 feet, and without cortisol any kind of minor trauma would instantly bring you into full shock and kill you

…However, if you are under physical or physiological stress that constantly “haunts” you, it’s likely that your cortisol levels are constantly high thorough the day.

That’s not good, since cortisol not only breaks down your muscle mass and causes oxidative damage in the body, but it’s also made from the same “raw material” (pregnenolone) as testosterone is, and high levels of cortisol can literally destroy your free testosterone molecules locally inside testicles and in the bloodstream. I’ve touched this subject before in here and here.


4. Lower your Endocrine Disruptor Exposure

endocrine disruptor chemicals and testosterone levelsThe definition of endocrine disruptor is as follows; “Synthetic chemicals or natural substances that may alter the endocrine system (consisting of glands, hormones, and cellular receptors that control a body’s internal functions) and may cause developmental or reproductive disorders.”

Compounds that act as endocrine disruptors in the body are used generously in modern personal care items, plastics, preservatives, pesticides, and many many other appliances.

Out of the millions of chemicals used, most are relatively harmless. However there are some compounds that have been proven to disrupt hormone production and functions in the body.

These include (but are not limited to);

  • Bisphenol A (BPA) which is a monomer used heavily in plastics and epoxy resins. Since BPA has a ‘hardening’ effect on plastics, its used generously in many industries,making BPA one of the most produced chemicals in the world. It also has hormone-like properties in the body and has been linked multiple times to low-testosterone and erectile dysfunction (study, study, study).
  • Parabens (methyl-, butyl-, ethyl-, propyl-, heptyl-, etc) which are preservatives used in nearly all kinds of cosmetics, such as; sun lotions, moisturizers, personal-lubricants, shampoos, shaving gels, toothpaste, and even as food additives. They’re classified as xenoestrogens, and can have a weak affinity to estrogen receptors in the body.
  • Phthalates which are commonly used to make plastics more flexible, but they are also used as stabilizers and emulsifying agents in many personal care items. Increased urinary phthlate traces have been strongly correlated with decreased testosterone in men, women, and children.
  • Benzophenones (BP-1, BP-2, BP-3…) which are permeability enhancing UV-stabilizers are used in a wide range of personal care items, but most commonly in sunscreens. Concerns have been raised of their effect in reducing the activity of enzymes needed in testosterone production. This has been studied for BP-1, BP-2, and BP-3.
  • Triclosan and Triclocarban, both of which are antibacterial agents found in many antibacterial soaps, lotions, hand sanitizers, etc. Not only are they highly ineffective at reducing bacteria, they also have direct mechanism in lowering testicular testosterone production.
 How to reduce the exposure then?  Well it gets to be pretty much impossible to avoid all exposure in the modern World, but you can slash your exposure significantly by using a tap water filter, drinking from steel or glass cups and bottles, using natural personal-care items, and eating less canned foods. Grocery store receipts are also coated with BPA, so better not fiddle around with them too much.


5. Spark Up Your Sex Life

sexual activity increases testosterone production naturallyAdmittedly one of the most satisfying ways on how to increase testosterone levels naturally is; sexual activity.

It’s not fully understood why this happens, but many studies have theorized that its an interplay with dominance, feeling of power, feeling of success, pheromones, dopamine, and interpersonal touch. For this reason it’s also likely that sex with an actual human instead of the palm of ones hand,would be a much better way to boost T.

Is there any research on increased sexual activity and testosterone levels? You bet there is.

A study of 44 men visiting a sex club actually showed that the guys who went there only to watch other people have sex, had an average increase of 11% in their testosterone levels, whereas the guys who went and actually had sex there noted an average increase of 72%. It’s also seen in couples that on the nights that there is “sexual activity”, testosterone levels are significantly higher than on the nights that they don’t have sex. One of the many findings in the Baltimore Longitudal Study on Aging was that in men over 60-years of age, those with higher level of sexual activity had significantly greater serum testosterone levels.

Much has been theorized about ejaculations and testosterone, and there seems to be this common misbelief that busting a nut would “drain” the body from testosterone (which fortunately isn’t the case). I recently wrote a more detailed article about the subject which can be found here.


6. Know the Side-Effects of Prescription Drugs

prescription medication that can lower testosterone levelsHealthcare is a business. A big business.

Chances are that if you visit a doctor – even without any known health issues – you’ll probably end up leaving with a prescription to some medication.

Therefore its not a coincidence – nor a surprise – to see that the largest pharmaceutical companies are raking in hundreds of billions of dollars annually.

In many cases, prescription drugs can prove to be vitally important to the patient. However, it’s also worth noting that in order for the pharmaceutical companies to make money – people have to be sick – and for some reason we are only treating the symptoms with more and more pills instead of actually focusing on the cause of the illness.

Though at the end of the day, your health is your own personal responsibility. Not the doctors. Not the governments. Yours.

With that being said, here’s some studies about prescription drugs that have side-effect of lowering testosterone levels (what ever you might do with this info is your decision);



7. TestShock Program

testshock and testosterone levelsWriting about natural testosterone optimization has been my job now for the past few years. Reading, learning, and researching info on hormones has been something I’ve done for ever since I was 15…

…As you can imagine, I have seen, read, bought, or sometimes straight up ignored hundreds of ‘T-boosting’ e-books, physical books, supplements, courses & programs, and even coaching. I get pitched some testosterone related products on a daily basis, since this site is currently the most visited ‘natural testosterone resource’, everyone wants their piece of the pie and their product to shine on the sidebar.

The problem is that I don’t want to promote bullshit in here, and that is exactly what 95% of the natural testosterone optimization programs and supplements are.

Not TestShock though. The moment I had read the first few pages of the book I knew that this was something different, something that aligns with the actual scientific evidence, and something that might truly be the ‘complete A-Z guide for how to increase testosterone naturally’.

 Now I don’t want to over-hype the program, but if you like to read articles like the one you’re reading now, and you’re interested in natural T-enhancement, then you’re going to love all the 262-pages of Christopher Walker’s TestShock program. 


8. Take a Look at Your Posture

body language and posture changes can raise testosterone naturallyAccording to an interesting study done by Cuddy et al. in Harvard University, your body language as well as postural changes can almost immediately impact your stress and steroid hormones.

In their research, the scientists wanted to know what happens to the bodily hormones when the subjects do either a set of ‘high-power poses’ (taking up more space, standing tall, hands on hips, dominant alpha stuff, etc) or ‘low-power poses’ (contractive behavior, closed limbs, taking less space, general insecure positions, etc).

Surprisingly, only in 2-minutes power-posing led to 20% increase in salivary testosterone levels, and -25% decrease in the stress hormone; cortisol. On the contrary, low-power posing led to a drop in T with accompanied rise in cortisol.

Here’s Cuddy herself talking about the topic and the study:


9. Money, Success, and Competition

money, success, competition and testosterone levelsI’m a big believer in the fact that making lots of honest money equals – at least in some form – happiness.

Not necessarily the fact that you can see the numbers in your bank account, but the fact that money (at least if you make it in your own terms) often equals total freedom.

Money also equals success in many fields, and can be a form of competition, or at least if not competitive, it generates the feeling that you’re “winning in life”.

Simply put, money is testosterone.

This study of young future-traders is a great example. In it, the traders noted higher testosterone levels on the days that they made above average profits. One young gun in the study ended up on a 6-day money streak and had 78% higher T-levels in serum as a result.

The results were likely caused by the fact that winning and success in almost any form of competition are both heavily correlated with increased testosterone levels (study, study, study, study), and what does a big pay day make you feel like? Winning of course. It doesn’t necessarily have to be money that generates the feeling of success. It can be sports, even watching sports, simply getting a list of tasks done, etc. Whatever makes you get the “genuine” feeling of being the boss and dominating your pursuits.


10. Testicular Health

testicular health and testosterone levelsRoughly 95% of the testosterone in your body is produced inside the leydig cells of the testicles…

…Because of this, it’s quite obvious that optimal testicular health and circulation would need to be one of the top priorities for all men.

For optimal testicular function, your balls actually need to be a tad bit cooler than the rest of the body, hence why they hang in a pouch outside of it. Because of this, sleeping naked, wearing loose boxers, and taking frequent cold showers can have a positive impact on your testosterone production.

Roughly 15-20% of men also develop a condition called “varicocele“, which is a thrombosis or “blockage” of some of the veins that lead to the gonads. Since varicoceles inhibit the normal blood flow to the leydig cells, they also inhibit the transportation of LH to its target, which causes your body to produce inadequate amounts of T. This is seen in many studies; men with varicoceles have significantly lower testosterone levels than control subjects, and when the blockage(s) are surgically removed, testosterone levels tend to increase significantly.

I guess some sort of testicular massage might also help in T production, though there isn’t (understandably) any research on that 😀 .


11. Check What you Smoke

smoking cigarette and anrdogen levelsTwo of the most common things that people smoke are; tobacco and marijuana.

The question is, how do they affect testosterone levels? Or do they even?

Looking at the scientific evidence behind tobacco and testosterone, it’s actually something that increases natural testosterone and DHT levels (study, study).

This effect is likely caused by nicotine, which acts as aromatase enzyme inhibitor (turning less testosterone into estrogen) and also blocks the conversion from dihydrotestosterone into a weaker metabolite 3-alpha-diol

…Then there’s also the metals and minerals in tobacco which can have androgenic effects, bottom line being that smokers tend to have bit higher T levels than non-smokers, even though smoking itself is not too healthy thing to do.

When it comes to cannabis, some studies say that the active ingredient (THC) can inhibit testicular enzymes needed in testosterone production and reduce T-levels, though the effects are reversible and not as significant as some people claim. In fact there have been few studies where smoking pot has not negatively impacted any hormones (study, study).


12. Alcohol in Excess is Not your T-Boosting Pal

alcohol can reduce natural testosterone levelsLet’s just start of by saying that no, you don’t have to completely cut off alcohol from your life in order to naturally raise testosterone levels.

Is it beneficial for T? Not in the slightest, in fact it has multiple mechanisms for lowering androgens, but in all honesty its effects on T-levels have been wildly exaggerated.

Sure if you’re an alcoholic who slams booze to the point of passing out on nearly all days of the Week, you can be damn sure that it crushes your test production, but few drinks here and there do not have that significant of an effect…

…Though, the mechanisms of action are bit scary;

How much do you have to drink to actually suppress test levels though?

The most damaging effects come from few rodent studies (study, study, study, study). One rat study in particular showed a staggering 50% reduction in testicular size after they were fed with a diet containing 5% of the calories from alcohol.

Rodents ain’t the only ones who see suppressed T-levels after alcohol ingestion. Heavy alcohol consumption has been linked to lowered testosterone levels in humans too (study, study, study, study). It’s also known that chronic alcoholics tend to have significantly lower levels of testosterone accompanied with significantly higher estrogen levels than their non-alcoholic peers (study, study, study)…

…Luckily enough, few studies have shown that low-moderate alcohol consumption isn’t that bad for male hormone production. Here an equivalent of ~2 glasses of red wine was associated with a mere 7% reduction in testosterone. In this one 0,5g/kg of alcohol actually slightly increased testosterone levels.

In the case of alcohol, the dose really does make the poison. Enjoying a few old fashioned’s or beers once in a while isn’t enough to chemically castrate you.



13. Caloric Intake Matters

your caloric intake can increase androgens naturallyIn order to make your body produce adequate amounts of testosterone, you need to give it enough calories to fuel the processes necessary in hormone production.

If you’re constantly feeding your body with a big calorie deficit, your body actually starts shutting down the reproductive system and conserves energy for more vital processes needed for your survival.

It doesn’t even have to be a massive calorie deficit, a 7-year study compared men who restricted their calories (1350–2415 kcal/day) and ate very “clean” against sedentary subjects who ate a normal Western diet with higher caloric intake (2145-3537 kcal/day). Due to their restrictive caloric intake, the group of men that ate lower amounts of calories had 31% lower testosterone levels, despite the fact that they maintained a “clean diet” and practiced running on a regular basis.

For optimal T production, consider eating a slight calorie surplus or maintenance calories.

The catch-22 here is that if you’re fat (which lowers testosterone), you MUST be on a caloric deficit to lose the weight, and the deficit itself can end up reducing your T-levels. So should you remain fat and make sure that you’re not getting too few calories? Or should you consider losing the weight by eating a calorie deficit and then bumping your calories up to maintenance level after you’re lean?

The answer is the latter option obviously.

When you start eating more after your weight loss success, your hormone production quickly shoots up, and as you lean down, it’s going to jump up to much higher numbers than what it was on a caloric surplus when you were still fat. If you want to lose weight slowly without really hurting your T-levels in the process, consider a really small deficit of only -15%, which has been shown to have no significant negative impact on testosterone production.


14. Protein is Necessary but not in Huge Quantities

protein is important for natural testosterone productionProtein is vitally important for muscle growth as well as testosterone production.

We know that chronic protein malnutrition causes low testosterone levels, while it’s also scientifically proven that roughly 0.8g/lb of lean mass is somewhat the point of diminished returns when it comes to the optimal amount of protein for muscle gains.

The problem is that the bodybuilding sites and magazines preach everyone to eat super-high amounts of protein (remember that they also sell you the protein), and protein IN EXCESS is not only useless for your muscle building goals, but it can also significantly reduce testosterone levels.

A study by Anderson et al. shows that when the male subjects undergo 10-days on a high-protein low-carb diet, their free-testosterone levels will be 36% lower than what they would be on a high-carbohydrate low-protein diet. High-protein diets also caused significantly higher cortisol (stress hormone) levels and – as to be expected from lowered bioavailable T – increased SHBG levels. Caloric intake and the amount of dietary fat was kept the same during both diets.

Another study, this time on resistance trained men, showed that dose-dependent reductions in testosterone were caused by increased percentages of energy from protein as well as increased protein to carbohydrate ratio.

The bottom line is that yes, you do need protein for both testosterone and muscle gains, but no, you don’t need as much as the fitness industry claims. For the optimal amount in terms of T-production, a good starting point would be ~20-25% daily calories from protein. As well as getting the majority from animal sources since plant-based protein is inferior to animal sourced when it comes to big T.


15. Carbs and then More Carbs!

carbohydrates increase testosterone levelsThere’s some unfair demonization going on against carbohydrates now. Or actually it has been going on for quite some time…

…The low-carb people say things like;

“Carbs raise insulin, insulin makes you fat, which is simply why carbs make you fat”, or the classic “Humans don’t need carbohydrates brah”.

The fact of the matter is that it has been scientifically proven that weight-loss has absolutely nothing to do with the amount of carbohydrates or other macronutrient trickery. Heck, you can eat the shittiest sugary snacks for all of your meals and still lose weight as long as you’re in a state of caloric deficit. Guess why? Because that’s how the human body works.

In the past few years as the “paleo diet” has become a thing, their so called “experts” have been telling people that since the cavemen didn’t eat a lot of carbs, we shouldn’t either. The thing is that they had absolutely no evidence to back up their claims about paleolithic humans not eating carbs. Recent evidence actually suggests that cavemen ate plenty of them.

The biggest reason why no man should go on a low-carb diet, is the fact that they’re notorious for lowering testosterone levels, increasing the stress hormone cortisol, and messing up with your sleep.

As explained in the above subheading, Andersson et al. found out that when caloric intake and fat intake are kept the same, diet high in carbs and low in protein leads to 36% higher free-testosterone level and lower cortisol production when compared to one with high-protein low-carbs. The study by Volek et al. Found similar results, go low on carbs and testosterone takes a hit.

When two groups of men undergoing intensive cycling 3x/week eat a diet of either 30% energy from carbs or 60% energy from carbs, the group which eats less carbs will have significantly lower free-testosterone levels. Similar results have been seen in a study with both men and women as subjects.

In this study, exercising men who are put on a low-carb diet, notice significant increases in the stress hormone cortisol (needless to say this is not a good thing). The pulastion rate of GnRH (master hormone that starts the testosterone production process) also seems to be heavily dependent on glucose availibity.

As a general rule of thumb, I’ve always recommended ~40% of daily calories from carbohydrates. Mainly from low-fiber low-gluten sources, since gluten may increase prolactin levels (study, study) and there’s some – although not very conclusive – evidence against high-fiber diets. To make it simple, eat the bulk of your carbs from potatoes and rice.


16. Dietary Fat Does the Trick

fat sources for low cost budget testosterone dietI’d say that fat is the boss macronutrient for testosterone production.

There’s plenty of evidence suggesting that increased amount of energy from dietary fat, leads to increased serum testosterone levels (study, study, study, study).

However, the type of fat matters A LOT. Saturated fatty-acids (SFAs) and monounsaturated fatty-acids (MUFAs) correlate very positively with testosterone levels, whereas polyunsaturated fatty-acids (PUFAs) and trans-fats effectively suppress testosterone levels (study, study, study, study, study, study).

A crucial part that is often left out in many articles is the part of different types fats having different effects on your hormones.

different types of fat and testosterone production

Bottom line: Ideally you’d want to keep your dietary fat intake at somewhere close to ~40% of daily calories, while most of them coming from SFAs and MUFAs with limited amounts of PUFAs and trans fats. In case you’re scared about the effects this would have on your cardiovascular system, there’s very little to be afraid of, recent research has showed that the link between saturated fat & dietary cholesterol with heart problems was never really strong, and the older studies have been debunked multiple times in more recent trials.


17. About that Sugar

sugar can increase or decrease testosteroneMuch has been said about simple forms of sugar (table sugar, honey, etc) reducing testosterone levels, and previously I used to believe that consuming sugar would be really bad for testosterone levels…

…now I’m not so sure anymore. Of course yes, there’s the research which shows that right after ingesting sugar, testosterone levels will drop acutely (study, study), but it’s crucial to understand that the act of eating pretty much anything is able to lower testosterone levels ACUTELY (study, study, study).

There’s no research that I know of which would of have linked sugar intake to long-term reductions in testosterone. In fact, the studies on carbs being pro-testosterone and GnRH increasing its pulsation rate in high-glucose environments speak towards the fact that sugar, which is basically what all carbohydrates eventually convert into, is not that bad for testosterone levels. It might actually be relatively good to consume some sugar on a daily basis.

In my opinion, sugar has been unfairly demonized. It doesn’t make you fat as everyone and their dog claims, overeating anything does. Sure it’s not that filling, and it might be more addictive than many other foods, but it’s not some toxic poison that destroys you from the inside out as is often boldly stated in click-bait headlines. Dr Ray Peat’s info on sugar is something I highly recommend to everyone who still lives in sugarophobia.

“The liver provides about 70% of our active thyroid hormone, by converting thyroxine to T3, but it can provide this active hormone only when it has adequate glucose.”Dr. Ray Peat


18. Plant-Based Diets are Not the Way to Go

vegan or vegetarian diets for increasing or decreasing testosterone levels naturallySure, you can learn how to increase testosterone levels on vegan/vegetarian diets if you know what you’re doing, but is it the optimal type of diet for T-production? No.

When you ditch all animal protein and animal fat, you’re in a situation where it’s really hard to get a balanced intake of amino-acid’s, enough cholesterol, and enough saturated fat to fuel your body’s testosterone producing needs. On plant-based diets men tend to also eat too much PUFAs in comparision to SFAs and MUFAs, which can further fuck up testosterone production…

…Not to mention that it’s increasingly harder to consume your daily caloric needs from plant-based foods alone (not to say that this isn’t possible, it’s just much harder).

Factoring those in, its no surprise that many studies have linked plant-based diets to lower testosterone levels. For instance, in this 1989 study changing from meat-based diet to plant-based one resulted in a 26% reduction in free-testosterone levels. Another study did the same thing with 30 male subjects and saw a 36% reduction in total testosterone levels on plant-based diet. Multiple other studies have noted that plant-based diets can lead to higher SHBG levels resulting in lower free-T and thus lower bio-availibity of testosterone for the androgen receptors (study, study, study)…

…Though this isn’t always the case, in one study it was noted that after adjusting BMI, vegans, vegetarians, and meat-eaters don’t really differ much in terms of testosterone levels. In fact in that singular study the vegan group had 6% higher total testosterone levels than meat-eaters.

 Which brings me to the point. You don’t necessarily have to crush your testosterone levels with vegan/vegetarian diets. If you can get in a good amount of calories, accompanied with some SFAs and MUFAs (coconut oil, olive oil, avocado oil, Macadamia nuts…), it’s likely that you can maintain high testosterone levels despite not eating any animal-products. 


19. Organic Produce for More T?

organic foods testosterone productionIn the case of eating organic foods for better testosterone production, it’s not about what you’re getting from the organically grown produce, but rather what you’re NOT getting from the conventional kind.

Specifically, I’m talking about pesticides, herbicides, insecticides, and growth/fat-promoting hormone traces.

Sure, organic foods are more expensive, and surely you don’t HAVE to switch everything organic in order to maintain high-T, and yes not all pesticides are harmful…

…But some can be. In this study, the researchers screened 37 commonly used pesticides for their hormonal actions in-vitro, as many as 30 of them were antiandrogens. Another study tested multiple pesticides for their effects on the 5-alpha reductase enzyme and saw that many of them had a mechanism for blocking DHT synthesis.

In a large-scale American study, it was noted that 91% of the US test subjects had notable amounts of the insecticide; chlorpyrifos in their bodies. In another human study, TCPY (3,5,6-trichloro-2-pyridinol) which is a metabolite of chlorpyrifos, was noted of having a dose-dependent testosterone lowering effect in multiple linear regression models. Several animal studies have also shown that chlorpyrifos has a significant testosterone lowering effect (study, study, study).

In isolated testicular leydig cells, one of the most widely used herbicides in the World; Glyphosate, had a direct testosterone lowering effect at normally occurring environmental dosages.

Two interesting studies from Denmark have showed that farmers who spray their crops with conventional pesticides experience lower sperm production and lowered sex hormones when compared to farmes who produce organic foods whom have higher sperm quality and higher sex hormone levels (study, study).

Many other pesticides such as organophosphates, Vinclozolin, PCBs, and Atrazine have been also linked to suppressed testosterone production.

NOTE: I’m not a fan of fear-mongering (think FoodBabe, Mercola, David Wolfe, NaturalNews), which is why I refrain from making any wacky tin-foil hat accusations about pesticide use. Indeed GMOs have saved thousands of lives in Africa, and in many cases there’s a legit reason to use crop-sprays, preservatives, and so forth. It’s always your personal decision whether you eat organic or conventional produce, or maybe you mix them up. The most important thing is that you read the evidence about them yourself instead of blindly following one expert with one specific stance, because in this subject, you’ll hear a bunch of bullshit from all-camps.


20. The Milk Controversy

milk decreases testosterone levelsIn terms of its macronutrient composition (high quality micellar casein, fats from mainly SFAs and MUFAs, and some carbs) and micronutrient composition (A, B1, B2, B12, D, choline, calcium, magnesium, and potassium) one could easily assume that milk is a pro-testosterone drink.

However, if we look bit deeper, there’s a problem with milk, especially the full-fat kind.

It’s the amount of hormones, in particular the naturally occurring mammalian estrogens, and especially in countries like US where the cows are kept pregnant (this increasing estrone content by up to 33x) for over 300-days of the year.

As a big-fan of milk, I was not happy to find this Japanese study where drinking cows milk resulted in increased serum estrogen and progesterone levels, which suppressed GnRH secretion from the brain and thus lowered testosterone secretion in men and prepubertal boys during a 21-day study period.

Since the conjugated hormones are mostly in the fat portion of the milk, it seems that skimmed and low-fat milk would be a hormonally better option…

…And indeed there are two studies which support this theory;

  • A study where physically active men drank full-fat milk and their overall sperm quality significantly decreased
  • A study where consumption of low-fat and skimmed milk increased sperm volume and mobility



21. Cholesterol is the Building Block

cholesterol to boost testosterone levels naturallyThere seems to be a correlation with the total amount of dietary cholesterol and testosterone levels – even though studies have also shown that the intake of cholesterol through nutrition doesn’t really do much to blood cholesterol levels in long-term.

An average sized male naturally synthesizes about 1-1,5g/day of cholesterol, while his body holds an additional amount of ~35 grams within cell membranes…

…It’s also known that the more cholesterol you consume through your diet, the less of it your body has to synthesize in liver, intestines, adrenal glands, and reproductive organs.

Bottom line is that all the steroid hormones are made from cholesterol, and even though your body naturally synthesis it on a daily basis – and controls the production accordingly to your dietary intakeincreased dietary intake of cholesterol, as well as blood levels of HDL cholesterol, are still positively linked to increased serum testosterone levels. So eat some egg yolks and make sure to keep your blood HDL (the “good” cholesterol) high.


22. Choose Coffee Over Tea

coffee is better than tea for testosterone levelsTea, especially the green kind, has been hailed as the supreme health drink for years…

…And surely enough there’s evidence that regular tea consumption can reduce your risk of certain cancers, offer slight protection from type-2 diabtes, and improve cardiovascular health. Some research even suggests that green tea consumption can aid in weight loss (although these effects are marginal at best and the green tea extracts sold as fat-burners are really not as effective as the producers claim).

Looking at tea from the hormonal point of view, it’s not so “supreme” after all;

I recommend choosing coffee instead, since not only does coffee taste better, it’s also pro-testosterone;



23. Intermittent Fasting for Androgen Sensitivity

intermittent fasting to increase androgen sensitivityDid you know that you don’t have to stuff your face with food for every few hours in order to boost T and maintain optimal rates of muscle growth?

Despite the fact that the fitness industry tries to sell you the idea of multiple small meals being “optimal”, science has actually shown that meal frequency does nothing to metabolic rate, eating fewer meals does not burn away your muscle or make it harder to build that, and for a fact, short-term fasting does not lower your testosterone levels.

In fact there are few interesting studies which have shown that after a short-term fast, your androgen receptors become more sensitive towards testosterone than what they would be if you’d eat on a constant basis. Even after 10-days of water fasting, re-feeding shoots testosterone levels higher than what the baseline was in the beginning. (study, study)…

I personally don’t recommend long fasts, although they can be useful in dropping weight. Instead I fast intermittently until every evening and eat all my calories post-workout, therefore theoretically taking advantage of that post-fasting anabolism and increased androgen sensitivity right after tearing the muscles in the gym.

 Intermittent fasting is a complex topic at first, and many so called “experts” are often making it even more complex by not fully understanding the research behind its benefits and how you should really fast in order to get the most out of the fasted/fed state “manipulation”. If you’re even slightly interested in IF, I highly recommend reading Brad Pilon’s Eat Stop Eat, which is nothing short of the COMPLETE guide to all things fasting. 


24. Eat these T-Boosting Foods

list of testosterone raising meals and food itemsLets face it, some foods are just better than others when it comes to boosting testosterone levels.

Much of this comes down to things like; high micronutrient density, high amount of protective antioxidants, high SFA or MUFA with low PUFA/trans-fats, quality animal based muscle-meat and collagen protein, low-gluten starchy carb sources etc. In fact I do have an article with 30 testosterone boosting foods over here

…But in case you’re looking for a condensed version with no additional ramblings, you can see one below:

Fats & OilsMeats & ProteinFruits & VegetablesNuts & SnacksSpices & Other
  • extra virgin olive oil

25. Limit your Intake of These T-lowering Foodstuffs

foods that can reduce testosterone levelsThere are of course also some testosterone lowering foods, and as much as I hate avoiding something or creating diets that are too restrictive, aka. prone to failure, certrain foodstuffs in high amounts just don’t fit the manly nutrition plant at all.

There’s definitely more than these, but this list is just for the ones with good amount of research to prove that. You can find a more detailed article with studies here.

Here’s the list in no particular order;

Testosterone Lowering Foods
  • Flaxseed products
  • Licorice
  • High-PUFA Vegetable Oils
  • Mint, Peppermint, Spearmint…
  • Soy Products
  • Trans-Fats
  • Alcohol
  • Green tea
  • High-PUFA nuts



26. The Endless Soy Debate

soya products reduce testosterone levels or not?There is a lot of conflicting evidence when it comes to learning how to increase testosterone naturally. For instance, whether the consumption of soy products lowers testosterone levels or leaves the amount of androgens unchanged is a matter of massive debate online.

Soy contains these compounds called isoflavones (genistein, daidzein and glycitein) which act as phytoestrogens (plant estrogens) in the human body. They’re structurally similar to the principal female hormone, estrogen, and are believed to have similar effects in the body. Since high estrogen level in men are almost always a direct route to lowered testosterone levels, eating soy – which contains estrogenic compounds – is often blamed for lowering testosterone.

Studies on the topic are highly inconclusive though, and while many of them do show that soy lowers testosterone levels (study, study, study, study, study, study, study), others show no apparent change (study, study, study, study).

I personally do limit my soy consumption, not necessarily because of the research on its effects for testosterone, but because soy is also chock-full of “goitrogens”, which are compounds present in foods, medication, or chemicals, that disrupt the production of thyroid hormones by interfering with iodine uptake in the thyroid gland.

Since thyroid activity is crucial for your energy levels and overall health, I’m not going to stuff my face with soy when I know there’s plenty of research suggesting that it can negatively impact thyroid activity…

…Also soy tastes awful and I’m not a vegan/vegetarian, so what real reason would there be to even consume it?


27. Hydration is the Key

hydration and water intake are important for testosterone to cortisol ratioWe all know how important water is for our cognitive function, exercise capacity, and overall bodily functions.

But many still take water as granted, and don’t drink nearly enough to really be in a good state of hydration. Even though it’s stupidly easy to just grab a steel bottle and fill it to the brim with the ever anabolic h2o.

During exercise the importance of drinking plenty of water is increased, since even mild dehydration will suppress the exercise induced rise in testosterone and growth hormone, while dehydration also increases cortisol secretion.

It has been shown in studies that even a mild 1-2% dehydration can significantly raise cortisol levels (study, study) and lower growth hormone secretion. One study by Volek et al. actually tested the effects between hydrated state, dehydration by 2,5%, and dehydration by 5% on their hormonal effects during exercise and saw that the less water the subjects drank, the higher their cortisol and lower their testosterone levels were.

hydration effects on cortisol and testosterone production


28. Resistance Training Recommended

resistance training is a good way to boost testosteroneTo up regulate androgen receptors in muscle tissue while also increasing testosterone levels both acutely and moving the baseline higher and higher can be best done with some form of resistance training.

There’s a mounting pile of evidence to suggest that resistance/strength training (basically lifting medium-heavy weights) can stimulate testosterone production in the short-term (study, study, study, study)…

…But also in the long-term by forcing the body to adapt into a new “normal” where your testosterone production is significantly higher even at rest mainly due to “forced” neuromuscular adaptations (study, study, study, study).

Resistance training is also generally very healthy, and it’s easily the best way for men to make your body look great, which amps up your confidence and can furthermore boost your T-levels due to those ‘feelings of success’ as explained in the subheading #9 of this article.

The idea is not just to “lift weights” in any manner that you can think of, but instead what you want to do for optimal hormonal response is to;

  • lift heavy enough
  • be explosive but still maintain form
  • activate large amounts of muscle mass
  • stimulate fast-twitch glycotic muscle fibers
  • do all of this in a short-period of time
  • rest properly.

All of the above pointers will be addressed more in detail in the below subheadings.

As mentioned previously, the THOR Testosterone Training program takes all of these factors into account, as the entire program was designed to increase testosterone and optimize your hormones through optimal training protocols. 


29. Do Some High Intensity Intervals

hiit or high intensity interval training is optimal for more testosterone productionWhen it comes to “cardio” high intensity interval training (HIIT) fits a testosterone boosting routine like a nose to the head.

Consider adding 1-2 quick HIIT-sessions on top of your resistance training routine to maximize exercise induced hormonal adaptations.

Due to its explosive nature, short-duration, activation of fast-twitch muscle fibers, and increased production of lactic acid – without being “chronic” enough to cause prolonged increases in stress hormones – HIIT, aka. short bouts of intense exercise can cause sharp increases in total testosterone, free testosterone, DHEA, growth hormone, and dihydrotestosterone (study, study, study, study)

Some examples of this type of training are;

  • regular sprinting
  • hill & wind sprints
  • circuit training
  • playing hockey
  • HIIT cycling

Here’s a great example of hill sprints that would be pretty great for hormonal response (courtesy of FitByGreen.com):

Bottom line: Basically any type of exercise where you can do quick 15-30 second all-out bouts of exercise in 2-8 intervals will work wonders for anabolic hormones and neuroendocrine adaptations. Instead of boring hours of steady-state cardio, consider crushing it with few all-out sprints for maximal hormonal gains.


30. Maintain Regular Physical Activity

regular physical activity increases serum testosterone levelsAside from lifting weights and sprinting your ass off, you should maintain some regular physical activity on a daily basis.

This includes things like walking, plowing the snow/mowing the lawn, chopping trees, and other sorts of recreational stuff.

Maybe a low-intensity hockey game with the lads? Some ball-games with the family? Anything that can be considered “active rest”.

There are even studies to show how effective regular physical activity is for T:

…A recent study from the Journal of Clinical Biochemistry and Nutrition observed 41 obese and overweight male subject who were put on a lifestyle modification program lasting 12-weeks, consisting of varied amounts of physical activity (measured by a pedometer) and reduced caloric intake. The goal of the study was to determine which one had the biggest impact on testosterone levels; increased physical activity or reduced caloric intake and the resultant weight-loss? After the 12-weeks had passed, the researchers found out that it was the high physical activity – not so much the magnitude of the calorie deficit – which was the driving factor in the subjects rising T levels.

(LPA = low physical activity, HPA = high physical activity, LCR = low calorie restriction, HCR = high calorie restriction).

Of course walking isn’t the only physical activity that boosts T-levels, when sedentary subjects are compared against “active” subjects, the more physically active guys do have higher sperm counts and testosterone levels. Also its seen in studies that when sedentary men start some sort of physical activity and/or low-pace exercise routine, their T levels tend to go up as well (study, study, study)…

…Take something as woodcutting as an example, in Tsimane tribesmen, 1-hour of chopping trees led to 46.8% increase in testosterone.


31. Cardio Before Weights? Train in AM or PM?

Training variables and testosterone levelsThe age old questions spanning around the fitness industry in relation to hormones and workout timing are;
— Should you train in the morning or evening for better testosterone levels?
— Should you hit the weights before cardio or the other way around?
The cardio question first. Sure, there are many opinions, but the actual evidence is suggesting that yes, cardio before weights is more ‘anabolic’.

In fact a study by Rosa et al. showed that the guys who hit cardio before weights had 7x higher post-workout testosterone levels than the guys who did cardio after weight training (due to ‘stimulus interference’ the researchers claim).

NOTE: Although the immediate post-exercise hormone alterations are not going to massively impact your physique or resting T-levels, its still good to have that 7x higher testosterone response once in a while huh?

When it comes to morning or evening training, it doesn’t really matter. Even though your T-levels are naturally highest in the morning, over long-term training increases testosterone levels in similar fashion regardless of the time of the day (study, study).


32. Lower the Amount of Endurance Training

endurance training reduces testosterone levelsI get that for some, dropping endurance training isn’t an option, maybe you compete in running or triathlon for example?

Though that doesn’t change the fact that endurance-type long steady state exercise is very good at lowering testosterone levels and causing chronically elevated cortisol response.

Research has shown that endurance cyclists and runners, but not swimmers, have significantly lower testosterone levels than sedentary controls. Furthermore male distance runners are known for having significantly lower than average testosterone levels (study, study, study, study, study).

It also goes without saying that your body will look quite weak and frail if you train mainly for endurance.

A much better option for those of us who don’t “need” to train for endurance, would be something like low-pace walking or hiking. Obviously resistance training and high-intensity intervals are the optimal way to train for T, but if you’re looking for a bit more lighter way to balance hormones, slowly walking with a small incline is actually much more beneficial for T and especially normal cortisol secretion than chronic endurance training.


33. Reverse Pyramid Training

reverse pyramid training for serious size and testosteroneReverse pyramid training (RPT) is a set/rep pattern used in resistance exercise movements where you (after warming up) hit the heaviest weight on your first set and then reduce some of that weight and add more reps to the 2nd and possibly 3rd set. This pattern is used by such guys as: Greg O’Gallagher and Martin Berkhan.

It’s a very demanding type of training, but it allows you to lift heavy loads of weight in relatively short amount of time and you don’t have to tax your central nervous system with multi-set workouts that eventually just turn into grinding and spinning your wheels. It’s a very good fit for testosterone boosting workouts (which is why it is one of the main themes in the THOR Testosterone Training program).

Basically reverse pyramid training comes down to first warming up, then hitting your first set with all-out effort of say for example 5-8 reps, then you rest for roughly 3-5 minutes and reduce the weight by 10% and do the same with 1-2 more reps than in the first set. If you want to do more sets, keep reducing the weight by ~10% and adding 1-2 reps. IMHO 2-3 sets is optimal (more than that is just unnecessary strain for the central nervous system).

Here’s an example of a RPT low-volume high-intensity back workout that I do personally;

  • 4 reps of deadlifts -> Reduce weight by 10%, rest ~4 minutes and do 5-6 reps of the same movement.
  • 5 reps of weighted wide-grip pull-ups -> Reduce the weight by 10%, rest ~4 minutes and do 7 reps of the same movement.
  • 8 reps of weighted chin-ups -> Reduce weight by 10%, rest ~4 minutes and continue with 10 reps of the same movement.
  • 6 reps of lat pulldowns with narrow handle -> Reduce weight by 10%, rest ~4 minutes and do 8 reps.

Aaand that’s it for the back, a total of 8 sets – which might seem like a ridiculously low amount of work – but when done correctly (1st set is really ALL OUT set) you’re actually going to be pretty done. Go ahead and give it a shot if you don’t believe my word 😉


34. Neuromuscular Movements

neuromuscular training to promote testosterone releaseNeuromuscular training (NM training) is something that Chris Walker introduced in the TestShock program and expanded on even further in the THOR Testosterone Training program

In short its a type of weight/bodyweight training that maximizes the stimulus of the nervous system, leading to maximal stimulus of the neuroendocrine system, leading to increased testosterone production and androgen receptor up regulation.

The way to do this is by activating large amounts of muscle volume (how much muscle mass you activate), with high intensity (how explosive you are), under a performance threshold (avoiding the negative adaptations that come with increased glugocorticoid receptor up regulation and chronic cortisol elevations).

Since increased muscle activation is known to increase the testosterone and growth hormone response, you’ll often see people saying that in order to boost testosterone you have to squat, squat, deadlift, squat and then do some deadlifts. And sure enough deadlifts and squats are very good movements for size and increased muscle activation, but they fall short on intensity (explosiveness) not allowing you to maximize the activation of fast glycotic muscle fibers, and they also bring you more easily to the training threshold.

Some movements which actually can be used for NM training to maximize all the above factors are;

  • weighted chin-ups and pull-ups
  • weighted dips
  • clean & jerk
  • muscle-ups
  • box jumps

Honestly, I’m not that good at explaining the principles of NM training, so lets hear it from the creator himself:

Researchers have found that explosivity encourages NM adaptations necessary to support the training demands (ie. indicating a long term adaptation), and that a training threshold very likely exists. We want to up-regulate AR content in fast glycolytic muscle tissue (as opposed to slow oxidative tissue). Resistance training is unanimously agreed upon as a potent stimulus for testosterone production and muscle growth, but the specific type is either not discussed or not agreed upon. What we do know is that resistance training promotes an increase in both AR mRNA (ie. gene transcription) and protein content and T concentrations. So combining both of these ideas, we can come to the conclusion that explosive resistance training is the optimal form of stimulus – as long as it is performed under the performance threshold (so as to continually promote AR up-regulation without compromising due to cortisol/stress-related suppression). But that’s not the entire picture. It’s also not entirely different from what the pop-fitness media promotes (though rarely practices). One more key element to the equation is often overlooked. And that’s the idea of work load and its relationship to muscle volume activation (MVA) relative to intensity.Chris Walker


35. Avoid the Pitfalls of Overtraining

avoid overtraining for maximum testosterone levelsIt seems to be in fashion now in the fitness circles to claim that overtraining would not exist. Sure, those guys claiming that are usually on steroids or don’t really know how to really work hard enough to really need recovery. Also their goal is rarely to maximize hormonal output.

If you workout with a reverse pyramid style doing neuromuscular movements and some HIIT cardio once in a while, you really can’t be lifting every day. You can try but eventually this will lead to sluggish progress and messed up hormonal response, which is exactly what were trying to avoid here.

In short, you want to workout 3-5 times a week with ALL OUT INTENSITY and then REST properly so that your muscles, endocrine system, and CNS are always primed for your next workout which will be slightly more intense/heavier.

Going to the gym with no energy and when you’re still recovering from the previous workouts does very little to your progress and only negatively affects the hormonal response.

Remember, constant progress is the key to gains and hormonal adaptations. In order to push for that increased testosterone response and to move your resting baseline higher and higher (creating the new “normal”) you have to get out of your comfort zone and constantly progress to heavier weights and higher intensities…

…A good example of this is a study where non-athletes experienced significantly higher testosterone levels after an intense lifting workout in comparison to elite athletes. For the sedentary subjects this was a huge step out of the comfort zone and forced the body to adapt to new training stimuli, resulting in hormonal adaptations, whereas for the elite athletes this was just “another workout” and the hormonal adaptations weren’t as strong.

Another study saw that after sedentary subjects started a resistance training routine, their baseline testosterone levels shot up by over 40% in just 4-weeks. Why? Likely because they had to get out of the comfort-zone and create a “new normal” to which their hormones had to adapt into.

That’s the idea behind constantly pushing yourself and getting to higher weights and better intensities as you get stronger and stronger, you’re slowly pushing the hormonal baseline up by forcing your body into using bigger workloads and heavier weights…

…If you overtrain, your lifts will start degrading and your CNS will be too taxed to actually make that constant progress, and that’s just one of the many reasons to avoid the pitfalls of training too much.



36. The THOR Program

Thor program by christopher walkerSomething that this whole natural testosterone optimization field has really been missing for years now is a specific training program with the goal of building the ultimate “masculine” body, while also focusing on maximizing the testosterone response of training.

The TestShock program has its own training section, which is good and definitely delivers more than great results, but it takes a high-level view of training and often spans variety of training related questions.

The THOR Testosterone Training program should be a definitive answer to most of them. It’s a completely training focused encyclopedia of how to EXACTLY train in a way that maximizes the amount of exercise induced long-term testosterone adaptations.

I’ve had a minor involvement in few of the topics of the book, and for now I can say that it contains multiple new ideas which haven’t really been discussed and/or applied to “hormonal response training” yet. Sure it has all the evidence-based teachings that are already well-known in this field, but also a TON of new and somewhat revolutionary info.

All I can say is that the THOR-program is not your average “more squats and deadlifts bro!” kind of book.



37. Get a Quality Multivitamin

multivitamin for increased testosterone levelsPerhaps one of the easiest ways to significantly increase your natural testosterone production, is by correcting all of your underlying micronutrient deficiencies.

In fact I would go as far as saying that the best “natural T-booster supplement” is in fact just a basic high-quality wide-spectrum multivitamin. Allow me to explain why…

…Even though many guys think they’re all topped up on all the necessary vitamins and minerals, they usually aren’t.

One study conducted by The Washington Council of Responsible Nutrition says:

“Large portions of the population had total usual intakes below the estimated average requirement for vitamins A (35%), C (31%), D (74%), and E (67%) as well as calcium (39%) and magnesium (46%). Only 0%, 8%, and 33% of the population had total usual intakes of potassium, choline, and vitamin K…”

When you start looking at how vitamin and mineral deficiencies affect your testosterone production, you’ll realize why its important to keep your body topped up on essential micronutrients;


38. Phosphatidylserine

phosphatidylserine and testosterone levelsNot much has been talked about phosphatidylserine (PS) as a testosterone booster, even though there’s some evidence that at least in exercising individuals, PS can reliably increase testosterone levels and suppress the exercise induced cortisol secretion.

Phosphatidylserine is actually a naturally occurring phospholipid complex present in all of the bodily cells. Its mainly a signaling molecule between cells and hormones, but may also have other functions, such as reducing the oxidative damage at the interior of cells.

Due to over 50% of the bodily PS being in neural tissue of the brain, many claims of phosphatidylserines “nootropic” or brain boosting benefits have been made. Surprisingly enough, there’s a good amount of evidence which suggests that PS supplementation can improve cognitive functions (study, study, study). In fact PS has an FDA granted ‘qualified health claim’ for prevention of cognitive decline in humans.

When it comes to testosterone, PS can improve athletic performance by reducing the exercise induced rise of oxidative stress (study, study, study). Furthermore, phosphatidylserine supplementation has a dose-dependent cortisol reducing and testosterone promoting effect in exercising subjects (study, study). In the latter study PS was able to improve the testosterone to cortisol ratio by 180% more in favor of increased T, aka. anabolism.

phosphatidylserine and cortisol and androgens

 This presentation explains bit more about the benefits of phosphatidylserine supplementation for stress-reduction and boosting testosterone levels. 


39. Bromelain

bromelain and testosterone levelsBromelain is a pineapple extracted blend of ‘proteolytic enzymes’. More specifically, it’s a supplement containing bunch of enzymes that can break down the peptide chains between amino-acids (proteins), improving digestion and absorption.

You can get some by eating pineapples, since the stem part is loaded with protelytic enzymes, but if you’re not a big fan of eating pineapple stems, supplemental bromelain is also available.

Why bromelain for testosterone you ask? This is actually more for the guys who want to do endurance training, since bromelain can preserve T-levels during ‘strenuous’ endurance training, but allow me to quote one of my older articles;

A study from the University of Tasmania by Shing et al. had fifteen young elite cyclists as their test subjects. The subjects were racing in a competitive cycle race for 6 consecutive days, and the researchers divided the participants into two groups. First one consisted of 7 cyclists who received 1,000 mg’s of daily bromelain. The second group consisted of 8 cyclists who received a visually similar placebo pill. During the six days of the cycle race, the researchers took blood samples from the cyclists at days 1, 3, and 6, and they examined these samples for various exercise markers, including testosterone. What they found out was very interesting. As to be expected, the high amount of endurance exercise significantly reduced blood testosterone levels – however – only in the placebo group. The group receiving 1,000 mg’s of bromelain, noted relatively stable levels of testosterone throughout the 6 days of cycle racing! Yup, that’s not a typo. 6 consecutive days of elite level cycling with no significant reductions in T levels. The researchers conclude: “Consecutive days of competitive cycling were associated with increased markers of muscle damage and a reduction in circulating testosterone across the race period. Bromelain supplementation reduced subjective feelings of fatigue and was associated with a trend to maintain testosterone concentration.” Mind you, this study is peer-reviewed, randomized, double-blind, and placebo-controlled. Not bad results from a gram of meat tenderizer per day I might say…


40. Ashwagandha Roots

withania somnifera cortisol suppressantAshwagandha (Withania Somnifera) is an Indian Herb, heavily used in their herbal medicine; Ayurveda.

When searching the internet, you can stumble upon some ridiculous claims about herbs, and ashwagandha is not an exception. Did you know that the name actually translates to “the smell of a horse”, and its claimed by some sort of shaman weirdos to actually give its user the power and virility of a horse. I call bullshit on that.

Even though there are those “herbal healers” who slowly smear the name of every single herbal compound, we can’t forget the fact that ashwagandha actually has A LOT of interesting Western medicine studies on its belt…

…Take a look at these for instance (copied from my older Ashwagandha article):

a) Since ashwagandha is an adaptogen, it should reduce stress, anxiety, and balance stress hormones (mainly cortisol). To my surprise, ashwagandha is actually well-proven to do all of those, while also improving subjective well-being. Take this well-done double-blind placebo study for example, where 300mg’s of KSM-66 ashwagandha given to human subjects for 60 days, was able to slash cortisol levels by 27%, while also greatly reducing anxiety and mental-stress in the test subjects. Another study with KSM-66 noted 14% reductions in cortisol, while in one study which used 5g of the root powder, up to 32% reductions in cortisol were noted in subject males who suffered from stress-related infertility. Multiple animal studies have come to same conclusions: ashwagandha supplementation consistently reduces cortisol levels and improves many stress-related symptoms.

b) When it comes to general-health benefits, there are many. For instance, ashwagandha can greatly improve cardiovascular health by reducing inflammation, reducing the amount of serum triglycerides, increasing the “good” HDL-cholesterol (~17%), and reducing the “bad” LDL-cholesterol (~9%). In one human study, ashwagandha was able to increase serum T-cell count, and killer-cell count, suggesting that it can boost immunity. At 250-500mg/day KSM-66 extract has also been shown to increase hemoglobin levels, which might be one of the reasons why ashwagandha constantly outperforms placebo-pills in studies examining power-output and anaerobic exercise capacity. One of the more recent studies published this year (non-sponsored, double-blind, placebo, peer-reviewed, aka. highly reliable kind) found out that 600mg/day of KSM-66 ashwagandga significantly increased muscle strength and recovery in 57 young male subjects.

c) So ashwagandha is in fact a pretty solid adaptogen, with a wide variety of benefits that have been proven in human studies, what could be better? Maybe the fact that there’s also solid evidence of the herb also increasing testosterone levels (actually that’s not a surprise, considering the fact that ashwagandha improves sleep quality, reduces cortisol, increases HDL-cholesterol, and reduces inflammation, all of which promote healthy testosterone production). Two human studies with infertile subjects (study, study) both using 5g/day of the basic root powder for 90 days, noted significant increases in testosterone (~40% and ~16% on infertile subjects and 15% in healthy subjects) with significantly improved sperm quality. One study with infertile men as subjects (this time with 675mg/day of KSM-66 for three months) showed a ~17% boost in T, with a ~36% increase in luteinizing hormone (LH), suggesting that ashwagandha stimulates testosterone production at brain level. Prior to 2015 there was no studies on healthy men that would show increases in testosterone, however, the study with 57 young and healthy male subjects as described in the paragraph above (using KSM-66 extract), showed a significant ~15% increase in testosterone levels (average rise from 630 ng/dL to 726 ng/dL, which is a lot from a single herb if you ask me).

NOTE: We recently added high quality KSM-66 to the marketplace as well as liquid extract of the roots!



41. Forskolin

forskolin is a potent testosterone boosting herbForskolin is a general term for standardized extract of an Indian plant Coleus Forskohlii. You’ve probably heard about it, since its a very popular fat burner and often hyped up in the ridiculous Dr. Oz show.

Aside from the facts that Oz is a clown who only smears forskolin’s name and that its not really anything super awesome as a fat burner, forskolin can actually increase testosterone levels and can also upregulate androgen receptors.

Forskolin is well-known for increasing cAMP (cyclic adenosine monophoshpate) levels in human tissue, and cAMP works as a secondary messenger in the body, transporting biological signals between cells and hormones. cAMP stimulation is believed to be the main reason why forskolin is able to increase T-levels.

The herbal extract so reliably boosts cAMP and testosterone levels in cell-culture studies that scientists often use it as a “positive control” to stimulate testosterone production in isolated testicular cells.

When forskolin was tested for its hormonal effects in humans, 12-weeks of forskolin at 250mg/day was able to increase testosterone levels by 33% when compared to placebo.

You could also call forskolin a “testosterone utilizer”, since it increased the amount of active androgen receptors in this in-vitro study. The mechanism is as follows: Forskolin stimulates cAMP -> cAMP stimulates an enzyme called protein kinase A (PKA) -> PKA stimulates the upregulation of AR.

 NOTE:When buying forskolin or coleus supplements, make sure its standardized to at least 20% active ingredient. Also don’t be bummed by the reviewers who say it doesn’t help with weight-loss, no supplement really does and the claims of forskolin doing that originate from the Dr. Oz show. We all know what kind of people buy supplements recommended by that fool (the nutcrackers). 


42. Creatine

creatine increases resting testosterone levelsCreatine is – right after protein supplements – the most popular supplement used by bodybuilders and various athletes.

It’s a naturally occurring amino-acid, which has a monster amount of scientific studies proving its positive effects in strength output and lean mass gain.

Creatine works by increasing cellular ATP (adenosine triphosphate) levels. ATP is what cells use as energy, so basically you’re increasing the supply of energy for your cells when you ingest creatine. Logically this helps you perform better.

But did you know that creatine can also increase testosterone levels? Not only the exercise-induced T-levels but also your resting baseline.

As a side note for a study that tested creatine’s effect on cognitive abilities, the researchers found out that it also increased salivary testosterone levels. In athletes creatine has been noted to reliably increase T-levels, for instance; This 4-year study noted that in athletes who reported using creatine, a trend towards increased testosterone levels was noted…

…In swimmers testosterone levels and swim times can be improved with creatine supplementation. In overtrained men who practice resistance training, creatine maintains power output, free testosterone, and total testosterone levels. One study even found out that creatine supplementation in resistance trained males led to 17% higher baseline testosterone levels than what was seen in the placebo group which received sugar pills.

Creatine is also known for increasing DHT levels by up to 56% in young rugby players.

 Creatine is a legit supplement for every athlete and gym-rat, since it increases strength output, reduces fatigue, and offers a slight boost to anabolic hormones. It’s also really cheap. 


43. Probiotics

probiotics can raise testosterone production naturallyThe definition of probiotics is as follows: “live micro-organisms which, when administered in adequate amounts, confer a health benefit on the host”. In other words, probiotics are friendly bacteria most commonly used to improve gut health.

The idea of using probiotic bacteria for health was first coined in 1907 by a Russian researcher and Nobel laureate Élie Metchnikoff who had a novel idea of replacing the harmful gut microbes, with beneficial (probiotic) microbes, this essentially improving gut flora and overall health.

These bacteria naturally occur naturally in many fermented foods, such as: yogurt, kefir, kimichi, sauerkraut, kombucha, and sourdough, and can also be supplemented with, currently it isn’t known which one is the better delivery method – supplements or food – but common sense would suggest its the naturally occurring kind from fermented foods.

What does all of this have to do with testosterone though?

Well for one, our gut health is strongly correlated with testosterone production. People with poor gut flora are much more likely to suffer from micronutrient deficits and lower T-levels…

…But it doesn’t end there, some modern research has shown that some strains of probiotics can directly increase testosterone levels. Take this 2014 rat study for example, where a probiotic strain commonly found in yogurts (Lactobacillus reuterii) was able to significantly increase multiple parameters related to reproductive health. In fact, the addition of L. reuterii to male rodents feed resulted in;

  • increased testosterone levels
  • increased testicular size and weight
  • increased markers of social domination
  • prevention of age-related testicular shrinkage
  • improved sperm quality, motility, and volume
  • increased luteinizing and follicle stimulating hormone levels

This isn’t the only rat study with promising results, another one found similar results, the more the rodents were exposed to probiotics, the higher their testosterone was. One study also saw that a probiotic strain by the name of Clostridium scindens is able to directly convert cortisol into androgens inside the gut.


44. The Estrogen Flush Stack

estrogen flush stackHigh levels of estrogens (female sex hormones) are not that uncommon in male bodies these days.

In fact, numerous things in our daily lives can increase estrogen levels and the conversion from testosterone to estrogen (which happens via the aromatase enzyme).

These include (but are not limited to); being fat, using personal care products with xenoestrogens, drinking lots of alcohol, drinking lots of full-fat milk from pregnant-cows, microwaving plastics, and yes, some men just naturally convert more of their testosterone to estrogen, as they’re “high aromatizers”.

How can you combat this and balance your levels?

Obviously, being lean, using natural personal care items, drinking less alcohol, not using too much plastic products, and switching to skimmed-milk can work wonders, but there are also some supplements that can be used in estrogen removal (you do need some estrogen for joint health etc, use the stack below if you have too much of it).

These supplements include;



45. Tongkat Ali

tongkat ali increases testosterone levelsTongkat Ali (Pasak Bumi, Eurycoma Longifolia) is a Malaysian herb with a massive reputation as a pro-erectile testosterone booster.

Some research suggests that it can lower SHBG levels, increase testosterone, block estrogen, and act as a powerful libido booster. Most of the studies are legit, but there’s also a bunch of studies and weird patents by a guy named Dr. Tambi, which are often cited, but are really hard to find online.

Taking a look at some of the research, we can see that there are several animal studies where Tongkat Ali has increased libido, erection quality, and even delayed ejaculations (study, study, study). In a test-tube study, Tongkat Ali has been shown to block estrogen similarly to Tamoxifen (popular synthetic estrogen blocker).

Looking at this patent application, there’s a citation where its claimed that Tongkat Ali works by stimulating the CYP17 enzyme in testicles. According to a rodent study, the active ingredients from the herb do make their way to the testicles, so it’s plausible that this mechanism could work.

The available human data is pretty interesting. In a study of 109 men, 300mg’s of Tongkat Ali for 12-weeks was able to improve semen mobility by 44% and volume by 18% when compared to placebo. According to a questionnaire that the subjects had to fill during the study, the Tongkat Ali group also noted significant improvements in libido and erection quality, sadly hormones weren’t measured in this trial.

The only study that tested hormonal effects, was this human study where “moderately stressed” subjects took 200mg’s of Tongkat Ali for 4-weeks. When compared to placebo, the TA group had 37% higher testosterone and 16% lower cortisol levels than the placebo group.

 Tongkat Ali has some good research behind its back, would have even more so if that Dr. Tambi guy would publish his studies online. Also if you’re going to get a Tongkat Ali supplement, consider purchasing the original Malaysian 200:1 water extract. 


46. Carnitine

carnitine to boost natural test productionL-Carnitine is a naturally occurring amino-acid (protein) found in meat. It’s usually used in supplemental form to either improve cognitive abilities or as a fat-burner.

Carnitine works by shuttling fat into the mitochondria for it to use as energy, this theoretically should improve your body’s ability to burn fat (although research on this isn’t too legit) and give your some extra energy.

The reason why carnitine is perfect for everyone interested in natural testosterone optimization, is that when carnitine shuttles the fat to the mitochondria, it also upregulates androgen receptor activity at the same time. This in turn leading to better androgen utilization by the body.

This effect has been shown in a study where 3-weeks of L-carnitine L-tartrate supplementation at 2g/day was able to significantly increase the amount of active androgen receptors in exercising human subjects. The researchers actually took muscle biopsies to be sure. In a previous study by the same researchers it was noted that even without exercise, carnitine is able to upregulate AR activity.

Since carnitine increases AR activity and also luteinizing hormone pulsation rate, it’s not a big surprise to see that it can very reliably increase sperm quality in human subjects (study, study, study, study).

Bottom line: If you want to maximize your tissue uptake of testosterone, consider adding carnitine to your supplement cabin. According to the studies you’ll get even more out of it if you exercise and take it immediately after training.


47. Royal Jelly

royal jelly increase testosterone levels naturally and safelyRoyal Jelly (RJ) is an anabolic porridge like liquid extracted from the hypophranyx glands of the worker bees.

Its the RJ fed to a small larvae which eventually makes it grow 60x bigger and live for 40x longer than the other bees in the hive. Basically Royal jelly is the food that makes the queen bee become queen bee.

Royal jelly is a nutrient bomb containing pretty balanced ratio of carbs (15%), protein (12%), and fat (5%), while also supplying vitamins: B1, B2, B3, B5, B6, biotin, and folic acid. RJ also contains the minerals: calcium, copper, iron, phosphorus, potassium, silica, and sulfur.

Rest of the ‘anabolic goo’ contains naturally occurring hormones, nucleic acid, sugars, gamma globulin, and ~3% compounds still unidentified by modern day science.

What does it do to testosterone levels? Here’s a quote from my older RJ article:

Royal jelly seems to be effective against infertility, as in this study, 25 mg’s of RJ taken for 3 months, was able to increase testosterone levels by 20% on infertile men. In another study where the subjects were healthy, a larger dose (3,000 mg’s) was given for the duration of 6 months. As a result, the RJ group increased their testosterone levels by 14% when compared to placebo. Albeit this isn’t a huge increase, there’s still one interesting factor in the study desing: the placebo group received a liquid control substance, which was similar to royal jelly in terms of vitamins and minerals, yet there was something in RJ that still managed to boost the test groups T by 14%. There’s also plenty of animal studies which also support the evidence that royal jelly has a testosterone boosting effect (study, study, study).


48. Shilajit

shilajit can raise androgen levels in menShilajit is a tar like resin collected from the deep rocks of Himalayan mountains.

No one seems to be entirely sure how it was formed, but I guess the most accurate theory is that it would be the end result of thousands of years worth of composed plant microbial metabolites, because of this its claimed that authentic shilajit can contain up to 85 minerals in their ionic form.

The research on shilajit is still in baby shoes, but one interesting study has been made about its effects on testosterone levels.

In the study, 60 infertile male subjects consumed 200mg/day of shilajit for a total of 90 days…

…After the three months had passed the shilajit treated group were found to have;

  • 37% higher sperm quality
  • 61% better sperm volume
  • 17% better sperm motility
  • 23% higher testosterone

NOTE: over 90% of the shilajit in the market is not authentic, and highly uneffective. True shilajit is always in its pure resin form and black.


49. Ginger Root

ginger to raise t levelsI think I mentioned ginger earlier in the nutrition part, but its worth to mention again as some might use it as a supplement too.

Ginger is generally hailed for its anti-inflammatory benefits, but its rare to hear anything about the fact that it can possibly increase testosterone levels.

Many animal studies have noted that ginger contains androgenic compounds, and could be used as an aphrodisiac in men (study, study, study). And yes, there is a human study on gingers effects for testosterone levels, which saw that an undisclosed amount of ginger administered daily for 90-days was able to increase LH (43%), FSH (17%), and testosterone (17%) levels in infertile men.

Whether ginger is able to do this on non-infertile men is a question we’re unable to answer yet, but due to its multiple health benefits and very low price, it’s not a big deal to try it out.



50. Horny Goat Weed

horny goat weed or epimedium in boosting t levelsHorny goat weed (Epimedium) is a flowering plant, native to the Mediterranean region of Asia.

For centuries, it has been used as a powerful aphrodisiac in Chinese medicine and due to its high levels of the compound called icariin, it might actually work to increase testosterone levels too.

Currently no human data exists, but many in-vitro and animal-studies have shown interesting effects with standardized icariin.

Here’s a quote from one of my older articles:

In this in-vitro study, icariin was found to be a natural PDE-5 and PDE-4 inhibitor (ED drugs like Viagra and Cialis work through PDE-5 inhibition). Even though icariin is not nearly as effective as the blue pill is, this could still explain some of the claimed aphrodisiac effects of horny goat weed. In the same study, it was noted that icariin activates the cAMP enzyme (due to PDE-4 inhibition), which is positively associated with increased testosterone production.

This rat study found out that at the dose of 80mg/kg icariin is able to triple testosterone levels, without changing the levels of gonadotropins (LH and FSH). The researchers claim that icariin acts as a testosterone mimetic in the body, and doesn’t stimulate the hypothalamus-pituiary-testicles axis like many other herbal T boosters do.

In few animal studies, icariin has suppressed the levels of the stress hormone; cortisol (study, study). As you might already know, elevated cortisol levels will suppress testosterone synthesis, due to the facts that elevated production of cortisol “robs” the cholesterol needed for testosterone synthesis, and high cortisol directly suppresses testosterone production inside the gonads.

Icariin is also very potent nitric oxide (NO) booster (study, study). Increased NO production will relax blood vessels and increase blood flow, and this might be one of the reasons why HGW is primarily considered to be an aphrodisiac (libido booster).


51. Mucuna Pruriens

mucuna pruriens to increase testosterone levels naturally in menMucuna pruriens (velvet bean) is an Indian herb commonly consumed in their herbal medicine; Ayurveda, as an aphrodisiac. M. pruriens has been widely studied in Western medicine and it is currently used in many medications to relieve the effects of Parkinson’s disease.

One of the claims that you will almost instantly stumble upon in the internet, is that mucuna supplementation would be able increase testicular size, and due to its possible effect in boosting testosterone production, this claim might actually hold some water.

The reason why mucuna would work to boost the big T, is that its chock-full of a compound called L-Dopa (levadopa), which is a precursor to the hormone/neurotransmitter; dopamine. Since increased dopamine secretion is linked to increased testosterone production, one could easily imagine that M. pruriens could stimulate T-production.

According to a bunch of studies, this seems to happen in subjects who consume the herb:

First of, there are several animal studies where Mucuna Pruriens has been able to increase testosterone levels and sperm parameters (study, study, study). Then came a human study where M. Pruriens was able to significantly increase sperm concentration on infertile and healthy men. (this could explain the proclaimed testicle size boosting effects).

Another human study followed, where 75 healthy and 75 infertile men, were given 5 grams of ground up Mucuna Pruriens for 90 consecutive days. The results showed that testosterone levels increased significantly (38% in infertile men and 27% in healthy men). Luteinizing hormone (LH) also increased (41% in infertile males and by 23% in healthy males). And prolactin decreased (-32% in infertile group and -19% in healthy group). Similar results were seen in this study, where Mucuna increased testosterone levels by 38% in infertile men (this study had no healthy men as subjects though).

NOTE: We recently added high quality mucuna extract to the marketplace!


52. Additional Resources for the Testosterone-Oriented

testosterone resourcesSince you made it down here, you must be pretty interested in natural testosterone optimization and no-BS evidence-based men’s health in general.

Even though this article is probably the best free resource for natural T-optimization, I have compiled below a bunch of additional resources for the four main categories…

…That is; lifestyle, nutrition, training, and supplementation advice which will help you become a superhuman (well at least kind of).

    #17 is hilarious and discredits a lot of your rational thinking and ability to check facts. This makes we want to go through all the studies you’ve mentioned on other points just to see whether you even know how to read them…

    1. Sugar IS toxic. Proven. Check studies.

    2. Sugar IS fairly demonized. There’s absolutely NO reason – not a single one – to have it in your diet. Proven. Check studies.

    3. Sugar DOES affect your body in many negative ways. Proven. Check studies.

    4. Sugar is at least as addictive as heroin, with some research pointing that it may be even MORE addictive than heroin. Check studies.

    Decent article overall, but some of the stuff coming from your personal biases is simply ludicrous.

    Thanks a lot Ali this is a great help, one question -I’ve taken ashmagwanda and though I’ve found it defiantly works i find that its effects wears off after about a month/6 weeks and I have to cycle it! What of the herb that you mentioned would be the best to cycle it with + from a t boosting perspective is a here any herbal supplement that I can take year round without having to cycle?

  11. Nils Salzgeber on 17/03/2016 at 18:19

        • Amar on 20/04/2016 at 19:18

          alcohol is a agonist for GABA meaning in acts as GABA in the brain. You are essentially consuming high amounts of the active chemical in alcohol without drinking. Doesn’t seem healthy in my opinion.

          • kyle893 on 23/04/2016 at 21:03

            Hmmmm interesting. Funny you mention it because I was taking gaba not too long ago and it was in a mixture with some other stuff. Anyways, I think it was causing me to wake up kind of uncoordinated and feeling just kind of weird. Dissociative I guess you could say, which makes sense because it’s related to the NMDA receptors somehow I think. It supposedly “can’t” cross the blood brain barrier, at least this is repeated despite the fact that it can and does, it’s just an unreliable mechanism in which it does. Low levels of gaba were insinuated to absorb more in the brain also. I didn’t have this issue as if I took the full 750 mg I felt very strange consistently and none of the other supplements in the mixture would seem to do this.

          • Amar on 23/04/2016 at 23:14

            Yea I wouldn’t take it anymore. Not worth the minor testosterone boost. If you are still considering taking it you should look for studies of its safety on pubmed and contact your physician.
