The biologically available part of total testosterone is called free testosterone, and it’s readily available to the cells. Almost every lab has a blood test to measure free testosterone. Even though it’s only a small fraction of the total, the free testosterone level is a pretty good indicator of low testosterone. It’s not perfect, but the correlation is greater than with total testosterone.
This post can absolutely change your life, and probably help you avoid some pitfalls. Like shrunken balls. (I am not an expert in the synthetic anabolic testosterone drugs used by bodybuilders — they carry lots of risks but pack a big punch if you want to get swole. Bulletproof is all about having massive clean energy, looking good, and living a very long time…so anabolic steroids aren’t on my roadmap.)
We start with plastic. A lot of plastic contains bisphenol A (BPA); BPA is a weak synthetic estrogen. Like many other chemicals used in making plastics, BPA is a hormone disruptor and can block or mimic hormones and how they act in the body (34). If you think you’re safe with BPA plastic, think again. Research shows that BPA free plastic has similar estrogen-like effects on the body.
A study out of the University of Mary Hardin-Baylor in Belton, Texas, examined the effects of fenugreek supplementation on strength and body composition in resistance-trained men. Researchers found that while both the placebo and fenugreek groups significantly increased their strength during the first four weeks, only the fenugreek group saw significant increases in strength after eight weeks of training and supplementation.[5]
Vitamin D: Recent research suggests a strong link between vitamin D and hormone function—but as much as 40 percent of Americans are estimated to be deficient. That’s where supplements come in: According to a study published in the journal Hormone and Metabolic Research, vitamin D-deficient men who also had low T experienced a roughly 25 percent increase in T levels after supplementing with 3,000 IU of vitamin D3 for one year.
Shilajit in its natural state has no chemical definition. In order to yield a consistent and efficacious form of shilajit, the shilajit is obtained from carefully selected rocks and is put through a patented technology where it is purified and standardized. This form of shilajit is now assured of optimal levels of bioactive components such as fulvic acid and dibenzo-pyrones, and is known as the patented PrimaVie.
For men with low blood testosterone levels, the benefits of hormone replacement therapy usually outweigh potential risks. However, for most other men it's a shared decision with your doctor. It offers men who feel lousy a chance to feel better, but that quick fix could distract attention from unknown long-term hazards. "I can't tell you for certain that this raises your personal risk of heart problems and prostate cancer, or that it doesn't," Dr. Pallais says.
Now, many men bypass the natty test booster category altogether, head straight for designer anabolic steroids, and start injecting testosterone (among other things). And, while exogenous testosterone administration will always trump the effects of natural testosterone boosters, that instant gratification does not come without a long, dreadful list of unwanted consequences.
Use natural grooming products. Most grooming products these days contain parabens, another type of xenoestrogen. And by most, I mean more than 75% of all products. To reduce my exposure as much as possible, I became a hippy during my experiment and started using all natural, paraben-free grooming products. You can find most of these items at most health food stores:
The changes in average serum testosterone levels with aging mean that the proportion of men fulfilling a biochemically defined diagnosis of hypogonadism increases with aging. Twenty percent of men aged over 60 have total testosterone levels below the normal range and the figure rises to 50% in those aged over 80. The figures concerning free testosterone are even higher as would be expected in view of the concurrent decrease in SHBG levels (Harman et al 2001).
A large number of side-effects have been attributed to testosterone. In our clinical experience, the incidence of significant adverse effects with treatment producing physiological testosterone levels is low, and many side effects attributed to testosterone are mainly relevant to supraphysiological replacement. Some adverse effects are specific to a given mode of delivery and have already been described. Potential adverse effects concerning the prostate have also been discussed and require appropriate monitoring of symptoms, PSA and digital rectal examination. Other tumors which may be androgen responsive include cancer of the breast and primary liver tumors, and these are both contraindications to testosterone treatment
There is a dirty little secret about testosterone cream that almost no one knows, and I’m going to share it here. Please don’t abuse it. If you take a vanishingly small dose of testosterone cream and apply it to your labia and the vulva (or your partner’s), you will witness a form of vasodilation rarely seen no matter how good you are in bed. It has a profound local effect and will produce a night you won’t forget for years.
Looking for ingredients that work in the realm of supplements can be like finding a needle in a haystack. Testosterone boosters, like all dietary supplements, are not approved by the Food and Drug Administration prior to marketing. This lack of oversight dates back to the 1994 Dietary Supplement Health and Education Act (DSHEA), which stipulated that purveyors of supplements weren’t required to prove the safety of their products or the veracity of what’s on the labels to the FDA before listing them for sale. Often, there isn’t a lot of scientific backing behind an ingredient, or research has been done solely on animals, not humans.

Rest and recovery is just as important as exercise, if not more so. Every time you do an intense workout, give yourself a minimum of 2 days to recuperate afterward, if not more. And don’t mix exercise with sleep hacking. If you’re exercising, get at least 8 hours of sleep every night. Your body uses it to rebuild, and you can throw your hormones out of whack if you don’t rest up properly. Here’s a more in-depth guide to Bulletproof weight training, complete with sample workouts.

61y/o with 18month progressive lethargy, depressed mood, no sex drive, no erections. Doc put me on cymbalta (slept even more than 14hrs daily) then on Wellbutrin. All the time I was pushing for T testing. Came back low in March of this year and put on IM cypionate 100mg q3 weeks. Even I knew that was too low and infrequent. Nonetheless, that how it’s been since April. Finally got urology consult in Shreveport and got a level done at that time. Was 127 just two weeks after last injection. He is going to bump me up to 300mg q2 weeks and do a level 2 days after first injection and 1 day before next shot. Since I’m getting care thru VA, it’s a waiting game. Saw urologist last week. Prob won’t see testostosterone in mail for another week or two. I’m excited to feel like living again, not sleeping all the time, and perhaps some nooky now and then . Appreciated this article arm subsequent posts and personal trials. Would love to find a competent and assertive urologist in my area of Louisiana. I’m around Monroe….so if you know one, let me know!


The oldest form is an injection, which we still use because it’s inexpensive and because we reliably get good testosterone levels in nearly everybody. The disadvantage is that a man needs to come in every few weeks to get a shot. A roller-coaster effect can also occur as blood testosterone levels peak and then return to baseline. [See “Exogenous vs. endogenous testosterone,” above.]

When the body cannot produce enough testosterone on its own, the term is called hypogonadism.  Testosterone boosters do not give the user actual testosterone (like with steroids), rather, they kickstart the production of this very important hormone.  For that reason, it’s important to find a potent formulation that has one or multiple key ingredients in it.


Testosterone is an anabolic steroid hormone that plays a critical role in metabolism, sex drive, muscle building, mood regulation, memory & cognitive function.  Normal testosterone levels play a huge role in maintaining optimal weight as well as reducing risk of degenerative diseases such as osteoporosis, heart disease, diabetes, & certain cancers (1, 2, 3).
Results from the clinical trial demonstrated that there were significant increases in hemoglobin in both men with unexplained anemia as well as men with anemia from known causes who used the testosterone gel. These results may be of clinical value, and testosterone treatment could be used to boost hemoglobin levels in men more than 65 who have unexplained anemia and low testosterone. However, more research needs to be done.
Ok. So this product is meant to be taken continuously and without side-effects. But my question is, will there be replenishment from this product in aiding the body's natural ability to produce testosterone? In other words, will there ever be a time when I can say well I don't have to take this any more as my body is producing testosterone again on it's own and my muscle mass has been enhanced?

According to studies by Srivastava [15] and Thomson et al. [21] ginger can be used as natural antithrombotic agent. Ginger has also been recorded as useful remedy in preventing post-operative nausea and vomiting in humans [13] as well as preventing morning sickness during pregnancy [16]. At high doses (500 mg/kg) aqueous extract of ginger exhibits cholesterol-lowering effect [21].

For example, testosterone can increase the hematocrit, the percentage of red blood cells in the bloodstream. If the hematocrit goes up too high, we worry about the blood becoming too viscous or thick, possibly predisposing someone to stroke or clotting events. Although, frankly, in a review that I wrote in the New England Journal of Medicine* where we reviewed as much of this as we could, we found no cases of stroke or severe clotting related to testosterone therapy. Nevertheless, the risk exists, so we want to be careful about giving testosterone to men who already have a high hematocrit, such as those with chronic obstructive pulmonary disease, or those who have a red-blood-cell disorder.
Next, while testosterone levels do decline with age, this may simply be because the older that men get, the less they take care of themselves – they stop exercising, start putting on weight, and don’t pay as much attention to their diet. A recent study suggests that age-related T decline is not inevitable, and that if you keep living a healthy lifestyle, you can maintain healthy testosterone levels. So if you’re an older guy, try to do all you can as far as lifestyle changes before you get on the prescription T. I don’t mean doing a little cardio a few times a week, using the machines at the gym, and eating “pretty” healthy. Follow the guidelines above, and see what happens first.

In non-human primates, it may be that testosterone in puberty stimulates sexual arousal, which allows the primate to increasingly seek out sexual experiences with females and thus creates a sexual preference for females.[39] Some research has also indicated that if testosterone is eliminated in an adult male human or other adult male primate's system, its sexual motivation decreases, but there is no corresponding decrease in ability to engage in sexual activity (mounting, ejaculating, etc.).[39]

The authors reported statistically significant increases in both noncalcified and total coronary artery plaque in patients receiving testosterone treatment. Participants’ coronary artery calcium scores, another measure of calcified plaque, were not significantly affected by testosterone treatment. Although these results are potentially a cause for concern, additional studies are required to determine the clinical relevance of this increase in plaque volume.
Testosterone is observed in most vertebrates. Testosterone and the classical nuclear androgen receptor first appeared in gnathostomes (jawed vertebrates).[193] Agnathans (jawless vertebrates) such as lampreys do not produce testosterone but instead use androstenedione as a male sex hormone.[194] Fish make a slightly different form called 11-ketotestosterone.[195] Its counterpart in insects is ecdysone.[196] The presence of these ubiquitous steroids in a wide range of animals suggest that sex hormones have an ancient evolutionary history.[197]
Other stereotypical "macho" behaviors can affect testosterone in women, according to a 2015 report in the Proceedings of the National Academy of Sciences. For example, posing in a powerful way increases testosterone in both women and men. The 2015 report showed that having women role-play a position of power — acting like a boss — had the same effect.
MuscleTech Pro Series Alpha Test claims you’ll be able to see increases in free testosterone levels in as few as seven days. Its formula is supported by potent ingredients such as Fenugreek, Shilajit, and Boron Citrate. The formulation can also help increase lean muscle mass, strength, as well as overall performance and maintains a peak testosterone-to-cortisol ratio.

Zinc is an essential mineral that plays an important role in improving testosterone levels as well as sperm production. Oysters are rich sources of this mineral. An increase in testosterone levels also helps improve your sexual desire and energy, which means that you are going to derive more pleasure from your sexual encounters besides having higher chances of conceiving.
“I'm 55 years old and hitting the ball further than I've ever hit, and I'm not getting tired going 18 holes! And when I play softball I'm hitting the ball further. I work for the DWP in LA and it's a very physically demanding job. Andro400 really helps because we work 16 hour days a lot. I was turning down a lot of overtime, but when I started taking Andro400, it got me through the day. I really notice a difference – even my wife did. It really works!”
As you can see, the entire workout is only 20 minutes. Twenty minutes! That really is a beautiful thing. And within those 20 minutes, 75 percent of that time is warming up, recovering or cooling down. You're really only working out intensely for four minutes. It's hard to believe if you have never done this that you can actually get that much benefit from four minutes of exercise. That's all it is.
Although it’s rare to see swelling caused by fluid retention, physicians need to be careful when prescribing testosterone to men with compromised kidney or liver function, or some degree of congestive heart failure. It can also increase the oiliness of the skin, so that some men get acne or pimples, but that’s quite uncommon, as are sleep apnea and gynecomastia (breast enlargement).
Today we take a look at some of the physical and psychological benefits that come with having optimal testosterone levels (I’ll talk about what “optimal” means regarding T later this week). You probably know about some of the benefits already, but some of the ones I discuss may surprise you. When appropriate, I’ll report any health benefits that I experienced during my own 90-day testosterone boosting experiment.
It doesn’t get more natural than getting a good night’s sleep. Research published in the Journal of the American Medical Association showed that lack of sleep can greatly reduce a healthy young man’s testosterone levels. That effect is clear after only one week of reduced sleep. Testosterone levels were particularly low between 2 and 10 p.m. on sleep-restricted days. Study participants also reported a decreased sense of wellbeing as their blood testosterone levels dropped.

Let me start out by saying that I didn't notice anything for about the first 10 days. After week 2, I had moderate energy increases buy by far the most noticeable difference for me was in the bedroom. After using this product for over a moth now, I normally run out of energy before I run out of "stamina". This will be a permanent regimen for my daily supplements from now on. I take 4 a day. 2 in the morning and 2 about 5pm. I thought about lowering the dosage to see if it had the same effect, but for the price, why? LOL.
Elevated testosterone levels have been demonstrated to increase the growth of body muscles and contribute to better activation of the nervous system, resulting in more power and strength, a better mood, enhanced libido, and many other benefits.[3] Previous researches done on the anabolic role of testosterone and its impact on muscular strength in training-induced adaptations has provided rather conflicting findings, and a positive correlation between testosterone-mediated responses and both functional performance and body composition was found.[4,5] There are a number of naturally occurring substances that can boost testosterone levels in the body. Foods containing such substances are known as testosterone-foods; and they tend to be rich in vitamins, antioxidants, and minerals like zinc, which plays a key role in testosterone production.[2,6-8]

Andy – If you take testosterone, your hypothalamus will notice an abundance of testosterone in your system and will instruct your pituitary gland not to send LH and FSH to your testicles. If you’re testicles are not receiving these two hormones, they will stop making testosterone. If you quit testosterone call turkey, you will likely fall back to your baseline level fairly quickly. There is a protocol however to get back to your normal production much quicker should you choose to quit therapy.

In addition to its role as a natural hormone, testosterone is used as a medication, for instance in the treatment of low testosterone levels in men and breast cancer in women.[10] Since testosterone levels decrease as men age, testosterone is sometimes used in older men to counteract this deficiency. It is also used illicitly to enhance physique and performance, for instance in athletes.

Studies conducted in rats have indicated that their degree of sexual arousal is sensitive to reductions in testosterone. When testosterone-deprived rats were given medium levels of testosterone, their sexual behaviors (copulation, partner preference, etc.) resumed, but not when given low amounts of the same hormone. Therefore, these mammals may provide a model for studying clinical populations among humans suffering from sexual arousal deficits such as hypoactive sexual desire disorder.[37]

Since then, multiple studies have found no link between high testosterone levels and increasing your chances of developing prostate cancer. However — and this is a BIG however — if you already have prostate cancer, increased levels of testosterone may exacerbate the problem. It’s best to wait until after you treat your prostate cancer before you begin any T-boosting regimens. Tread carefully and talk with your doctor.
I read several comments about blood clots. The issue was more than likely caused by estrogen overload and the measurement of ultra sensitive estradiol would prove it. I would wager that given T without anastrozole and having belly fat, that aromatase enzyme converted T to estrogen and that is why clots developed and why they felt worse instead of better. That is my opinion.

Caffeine. Use caffeine moderately. Too much of the jittery juice increases cortisol, which decreases testosterone. Moreover, consuming caffeine late in the day hurts sleep, which lowers testosterone production. But one recent study indicates that caffeine consumed before working out may boost testosterone levels and help you exercise more efficiently. During my experiment I popped a piece of caffeinated gum five minutes before my workouts. Each piece had 100 mg of caffeine, about the same amount in a cup of coffee. That was usually it for my caffeine intake that day.

The rise in testosterone levels during competition predicted aggression in males but not in females.[90] Subjects who interacted with hand guns and an experimental game showed rise in testosterone and aggression.[91] Natural selection might have evolved males to be more sensitive to competitive and status challenge situations and that the interacting roles of testosterone are the essential ingredient for aggressive behaviour in these situations.[92] Testosterone produces aggression by activating subcortical areas in the brain, which may also be inhibited or suppressed by social norms or familial situations while still manifesting in diverse intensities and ways through thoughts, anger, verbal aggression, competition, dominance and physical violence.[93] Testosterone mediates attraction to cruel and violent cues in men by promoting extended viewing of violent stimuli.[94] Testosterone specific structural brain characteristic can predict aggressive behaviour in individuals.[95]
A number of epidemiological studies have found that bone mineral density in the aging male population is positively associated with endogenous androgen levels (Murphy et al 1993; Ongphiphadhanakul et al 1995; Rucker et al 2004). Testosterone levels in young men have been shown to correlate with bone size, indicating a role in determination of peak bone mass and protection from future osteoporosis (Lorentzon et al 2005). Male hypogonadism has been shown to be a risk factor for hip fracture (Jackson et al 1992) and a recent study showed a high prevalence of hypogonadism in a group of male patients with average age 75 years presenting with minimal trauma fractures compared to stroke victims who acted as controls (Leifke et al 2005). Estrogen is a well known determinant of bone density in women and some investigators have found serum estrogen to be a strong determinant of male bone density (Khosla et al 1998; Khosla et al 2001). Serum estrogen was also found to correlate better than testosterone with peak bone mass (Khosla et al 2001) but this is in contradiction of a more recent study showing a negative correlation of estrogen with peak bone size (Lorentzon et al 2005). Men with aromatase deficiency (Carani et al 1997) or defunctioning estrogen receptor mutations (Smith et al 1994) have been found to have abnormally low bone density despite normal or high testosterone levels which further emphasizes the important influence of estrogen on male bone density.
I am a 67 yo male diagnosed with prostate cancer gleason 6. I have a prescription on bicalutamide 50 mg a day since Nov 2016 and leuprolide 11,5 mg every 3 months. My testicles reduced their size to half it´s original size, my libido is almost zero. I went through a radiotherapy of 45 sessions; my PSA level went from 11.2 to 0.13 on my last test from Sept 2017 and the leuprolide injections are taken away from my prescription by my urologist. I am planning to take TRT with Testosterone mix called SUSTANON 250 mg per week and HCG 5000 IUs twice a month. Give me your thoughts please
How alpha are you? Well, how many shakes of hot sauce can you handle? A recent study from France found men who have a taste for spicy foods tend to have higher testosterone levels than those who can’t handle the heat. Of the 114 male participants surveyed, researchers saw a clear correlation between frequent hot-sauce usage and higher T-levels. Study authors suggest the findings may be due in part to capsaicin—the fiery compound in chili pepper that previous studies have associated with increased testosterone levels. In animal studies, capsaicin has also shown to increase the size of sex organs, while simultaneously decreasing belly fatbelly fat. Yowza!

Pine Pollen is an androgen, meaning in theory it can raise testosterone levels – effectively making it a naturally derived source of testosterone. Read more about this on the links below. But like I said I started taking it for a few weeks and did notice a bit more ‘up and go’ so to speak, but it did only last a few weeks. I have tried cycling it but haven’t noticed the same effects as I had when I initially started with it. I’m still experimenting and will keep this page updated. Therefore I recommend doing your own research.
What are the side effects of testosterone pellets? Testosterone is the male sex hormone, and its levels in the body decline steadily with age. Many people wish to supplement it when they are deficient. Testosterone pellets can be a convenient form of testosterone replacement therapy, but they can cause side effects, such as fluid retention and acne. Learn more here. Read now
‘Testosterone boosting’ products  - found online, or in health food or body-building shops, these products claim to boost testosterone levels if you buy them. The majority of these products will not have the effect you want and are not worth spending money on. Any of these products that do have a real effect may have a form of prescription medication in which is both dangerous and illegal.

More recently, a study from 2015 noted that consuming 600mg daily of standardized fenugreek extract for eight weeks increased free testosterone levels compared to placebo. The test group also experience an increase the the number of repetitions the could perform in the leg press before reaching failure. And, to top it off, subjects receiving the fenugreek supplement dropped body fat without losing strength.


Testosterone replacement therapy is currently only FDA approved for men who have been diagnosed with hypogonadism, but it’s also prescribed off-label for older men who take it in hopes that it will improve their libido. The use of testosterone therapy is increasingly common in the United States, with more than 2 million men receiving the therapy. Not every man benefits from taking testosterone supplements. Testosterone is available in different forms, including topicals such as gels, creams, and patches; injections; and pellets that are surgically placed directly beneath the skin. (7)
