If you do take DAA I recommend cycling it (i.e. 5 days on, 2 off, over 4 weeks then 4 weeks off). And taking it with an aromatase inhibitor (which ensures the aspartic acid doesn’t get converted to estrogen). Especially as more studies are coming out showing the increase in testosterone is limited to a week or two before it drops back to normal levels.

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.
Statins are some of the most prescribed drugs in the world for reducing cholesterol levels and preventing heart disease. Various studies in the 1990s, including a study published in the ‘European Journal of Clinical Nutrition,’ supported the claim that Fenugreek could help reduce cholesterol levels[2]. One possible explanation is the high fiber content in fenugreek.  A fiber-rich diet has been shown to help reduce the levels of LDL (‘bad’ cholesterol) in your blood. (Note: The validity of the various studies from the 1990s have been questioned though because of small sample sizes[3])
“I see people who've been doing things in the gym and they've never been told that it can shut off your own production and it can also irreversibly lower your sperm count,” says Roked. “These are all quite serious issues that even though they may be rare if it happened to you it would cause a big impact on your life, so I'd say it's always best to do things with a specialist, but also for anyone it's not a great idea to take things that aren't needed."
Research shows that bone density increases with testosterone treatment as long as the dose is high enough. on the effect of testosterone on bone density found increases in spinal and hip bone density. Another of females transitioning into males found that testosterone increased bone mineral density. But it’s unknown if testosterone can help with reducing fracture risk.

Before assessing the evidence of testosterone’s action in the aging male it is important to note certain methodological considerations which are common to the interpretation of any clinical trial of testosterone replacement. Many interventional trials of the effects of testosterone on human health and disease have been conducted. There is considerable heterogenicity in terms of study design and these differences have a potential to significantly affect the results seen in various studies. Gonadal status at baseline and the testosterone level produced by testosterone treatment in the study are of particular importance because the effects of altering testosterone from subphysiological to physiological levels may be different from those of altering physiological levels to supraphysiological. Another important factor is the length of treatment. Randomised controlled trials of testosterone have ranged from one to thirty-six months in duration (Isidori et al 2005) although some uncontrolled studies have lasted up to 42 months. Many effects of testosterone are thought to fully develop in the first few months of treatment but effects on bone, for example, have been shown to continue over two years or more (Snyder et al 2000; Wang, Cunningham et al 2004).


Get out of here with your quackery nonsense. No one likes trolls that want to push diet and weight loss pills as a serious solution to low t and ED. Anyone who reads your comment will waste at least 20 seconds of their life. What’s worse, they might listen to you instead of getting real medical advice that might actually help with an issue that is devastating to their lifestyle. And btw, before you decide to respond to this with more quackery, testimonials or fake research, know that I am a pharmaceutical scientist and won’t fall for your bogus statements
What are the health benefits of kale? Kale is a leafy green vegetable featured in a variety of meals. With more nutritional value than spinach, kale may help to improve blood glucose, lower the risk of cancer, reduce blood pressure, and prevent asthma. Here, learn about the benefits and risks of consuming kale. We also feature tasty serving suggestions. Read now

Testosterone is responsible for increased muscle mass. Leaner body mass helps control weight and increases energy. For men with low testosterone, studies that treatment can decrease fat mass and increase muscle size and strength. Some men reported a change in lean body mass but no increase in strength. It’s likely you’ll see the most benefits when you combine testosterone therapy with strength training and exercise.
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]
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.

In fact, there is increasing evidence of the potential benefits of testosterone replacement therapy on multiple cardiovascular risk factors. This evidence recently has been comprehensively reviewed by Traish et al. in the Journal of Andrology.16 Although the full effects of testosterone replacement therapy on cardiovascular risk are yet to be established, the balance of emerging evidence from clinical studies suggests that testosterone replacement therapy in hypogonadal men may improve endothelial function, reduce proinflammatory factors, reduce hypertension, and improve the lipid profile.

The final two studies looked directly at soy vs testosterone levels. The first looked at introducing consumption of soya flour on testosterone levels. They found that those who ate the Soy flour lowered their T levels during the study (43). And the second study looked at the consumption of soy protein isolates (powder) in healthy men. They found that testosterone levels decreased upon consumption of soy powder (45).


Like other steroid hormones, testosterone is derived from cholesterol (see figure).[128] The first step in the biosynthesis involves the oxidative cleavage of the side-chain of cholesterol by cholesterol side-chain cleavage enzyme (P450scc, CYP11A1), a mitochondrial cytochrome P450 oxidase with the loss of six carbon atoms to give pregnenolone. In the next step, two additional carbon atoms are removed by the CYP17A1 (17α-hydroxylase/17,20-lyase) enzyme in the endoplasmic reticulum to yield a variety of C19 steroids.[129] In addition, the 3β-hydroxyl group is oxidized by 3β-hydroxysteroid dehydrogenase to produce androstenedione. In the final and rate limiting step, the C17 keto group androstenedione is reduced by 17β-hydroxysteroid dehydrogenase to yield testosterone.
However, if you have normal testosterone levels and are looking for a boost, for strength gaining purposes, then D-Aspartic acid use may prove less fruitful. A study published in Nutrition Research showed that when the booster was given to men who resistance trained four times a week, their body composition and muscle strength was no different to men who took part in resistance training without the aid of D-Aspartic acid.
Thus, alcohol metabolism destroys the essential coenzyme required for T synthesis. Alcohol also contributes to the release of special endorphins which inhibit hormone production. In addition, drinking too much alcohol leads to the elevation of estrogen levels in men because of the conversion of testosterone in estrogen. It means that T levels come down with a run.
If low T is your initial concern, lifestyle changes may help. “Dietary and exercise changes, particularly limiting sugars, especially fructose, eating healthy saturated fats, and engaging in high-intensity exercises may relieve symptoms of low testosterone," Lucille says. "Strength training, reducing stress, and optimizing vitamin D levels can also be very effective at boosting testosterone levels naturally."

It may also become a treatment for anemia, bone density and strength problems. In a 2017 study published in the journal of the American Medical Association (JAMA), testosterone treatments corrected anemia in older men with low testosterone levels better than a placebo. Another 2017 study published in JAMA found that older men with low testosterone had increased bone strength and density after treatment when compared with a placebo. 
Another study in 2015 by Melville and friends gave subjects either three or six grams of DAA per day for a 14 days (2 weeks). Researchers noted that the 3g dose of D-aspartic acid did not result in any meaningful changes in testosterone levels (or any other anabolic hormones for that matter).[3] However, the group of men receiving 6g per day experienced a significant reduction in both total testosterone and free testosterone levels, with no concurrent change in other hormones tested.[3]

Studies have demonstrated reduced testosterone levels in men with heart failure as well as other endocrine changes (Tappler and Katz 1979; Kontoleon et al 2003). Treatment of cardiac failure with chronic mechanical circulatory support normalizes many of these changes, including testosterone levels (Noirhomme et al 1999). More recently, two double-blind randomized controlled trials of testosterone treatment for men with low or low-normal serum testosterone levels and heart failure have shown improvements in exercise capacity and symptoms (Pugh et al 2004; Malkin et al 2006). The mechanism of these benefits is currently unclear, although a study of the acute effects of buccal testosterone given to men with chronic cardiac failure under invasive monitoring showed that testosterone increased cardiac index and reduced systemic vascular resistance (Pugh et al 2003). Testosterone may prove useful in the management of cardiac failure but further research is needed.
One study showed that six months of zinc supplementation among slightly zinc-deficient elderly men doubled serum levels of testosterone. And another eight-week trial found that college football players who took a nightly zinc supplement showed increased T-levels and increased leg strength that was 250 percent greater than a placebo! Holy quads, Batman! Research has also shown deficiencies in zinc to be a risk factor for infertility caused by low testosterone levels.
We scoured the database of the National Center for Biotechnology Information (part of the U.S. National Library of Science) for articles. Of the many ingredients marketed as boosting testosterone levels, we only found four backed by multiple articles based on human testing. For the best chance of boosting testosterone levels, a supplement needs to contain magnesium, fenugreek, and longjack — and some zinc wouldn’t go astray, either.
TestoGen USA stood head and shoulders above the rest, which is why it earned the top spot on our list. This testosterone supplement will help keep men on a more even keel when it comes to both stamina and temperament. You won’t feel wiped out at the end of the day and you’ll be less likely to feel your tension levels rising as you deal with everyday annoyances. In addition, it will stimulate your libido and can even help you lose excess body fat.
Keep in mind that you can use virtually any type of equipment you want for this – an elliptical machine, a treadmill, swimming, even sprinting outdoors (although you will need to do this very carefully to avoid injury) -- as long as you're pushing yourself as hard as you can for 30 seconds. But do be sure to stretch properly and start slowly to avoid injury. Start with two or three repetitions and work your way up, don't expect to do all eight repetitions the first time you try this, especially if you are out of shape.
Our bodies need zinc to make testosterone. Zinc also blocks the action of aromatase, the enzyme that converts testosterone to estrogen. Oysters offer the highest amount of zinc per serving of any food. Just six oysters contain about 500 percent of the mineral’s recommended daily allowance (RDA). Other zinc-rich foods include lean meats and spinach.

I am still on T therapy. But here’s what pisses me off: No one tells you that you will be hooked on the drug virtually forever! Don’t ever stop it abruptly! I did and I had a major crash: physically and emotionally. I went into the darkest depression ever…and I was lacking in energy so much that I had to have 4 naps a day…just to get through the day. I was also robbed of any initiative to do anything.
Cholesterol is the building block of testosterone, and eating healthy fats, including saturated fats, helps your body make “good” cholesterol while also supporting healthy hormone balance. Give your body a dose of healthy fats and proteins by consuming moderate amounts of meats from hormone-free animals, grassfed cattle, and wild-caught fish. Nosh on healthy-fat sources such as olives, nuts, seeds, avocados, and coconut oil.

Whether you are currently on a plateau or you are looking to obtain more energy in life and in the gym this test booster and its full coverage blend of natural extracts is designed to support your body’s anabolic potential without compromising natural production. Test Booster 1.0 works with your body to promote elevations in natural test levels; helping to support muscle density, a balanced metabolism, and insane natural energy levels.
As mentioned earlier, too much protein can negate testosterone production quite a bit. If your protein intake is over 0.85g/lb of body weight a day, then you may not be making full use of each of the nutrients. Consuming these high amounts of protein can cause your cortisol and SHBG levels to increase, which in turn lowers testosterone production. What do you get out of this deal? Increased fat gain and lower testosterone levels.
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].

Mood disturbance and dysthymia are part of the clinical syndrome of hypogonadism. Epidemiological studies have found a positive association between testosterone levels and mood, and depressed aging males have lower testosterone levels than controls (Barrett-Connor, Von Muhlen et al 1999). Furthermore, induction of a hypogonadal state during treatment of men for prostate cancer leads to an increase in depression scores (Almeida et al 2004). Trials of testosterone treatment effects on mood have varied in outcome. Data on the effects on men with depression are conflicting (Seidman et al 2001; Pope et al 2003) but there is evidence that testosterone treatment of older hypogonadal men does result in improvements in mood (Wang et al 1996) and that this may occur through changes in regional brain perfusion (Azad et al 2003).
Herbalists have used _Trifolium pratense_, red clover, to treat menopausal symptoms like hot flashes. The mechanisms underlying these effects remain unknown. Testosterone decreases hot flashes in some postmenopausal women, so red clover may work in this way. A 2015 paper in the Avicenna Journal of Phytomedicine reviewed the literature testing this idea.

I’m a 70 year old male. Here’s my brief story, I was exhausted all the time after an encounter with H-Py-Lori. After may tests it was found out that my T-count was at about 250. I was put on a testosterone cream replacement therapy. Before I knew it, at about month I was at 1500 count. This was at 4 cream applications a day. The doctor took me down to twice/two applications a day, now I was at 600. I felt great at both levels.
Are you getting enough vitamin D? Vitamin D is an essential nutrient, but it can be difficult for people to know if they are getting the right amount. Some people will be able to get enough vitamin D from sunlight. Others may need to make dietary changes or take supplements. Here, we explain how to get vitamin D from sunlight, food, and supplements. Read now
BCAA peptides are the building blocks of muscle.  Your body cannot make BCAA’s.  You have to eat them.  One easy way of course is food and things like whey protein powder.  That is why whey protein works so well because it contains BCAA’s at high levels.  Advanced BCAA is 50% BCAA in peptide form!!  Peptides are digested faster and more efficiently than whole foods and normal protein powders.  This means more muscle building and recovery support!!
Such sort of injuries varies in severity and extent of damage markedly from one person to the other and withdrawal of the drug/supplement coupled with proper medical attention suffice in terms of alleviating the symptoms.[8,12] This was observed in the present case. However, the liver injury observed here may not be confidently linked to product consumption as the subject later reported that the following recovery he consumed two more courses of the booster with no side effects. Tests performed following hospital discharge, and repeated use of the product showed AST and ALT to be slightly high, whereas the rest of the blood parameters tested appeared to be normal. The AST/ALT ratio is considered to be a very important parameter for the evaluation of liver diseases, such as non-alcoholic fatty liver disease,[13] though it is rarely considered alone. Overall, the evidence was inconclusive in the present work in terms of linking the use of a testosterone booster with liver injury. However, even though a single case report cannot establish causality with statistical power.[13] Further research on the usage of a commercial testosterone booster within large populations for a long period is necessary to investigate whether the symptoms shown in the present case were significantly present in other athletes consuming the same commercial product or not. To guarantee an optimal outcome with no severe side effects, further research is warranted to confirm the present findings and determine whether the effects observed in this case report would be statistically significant in larger samples.

There’s a significant failure rate of the PDE5 inhibitors for erectile dysfunction, something on the order of 25% to 50%, depending on the underlying condition. It turns out that a third of those men will have adequate erections with testosterone-replacement therapy alone and another third will have adequate erections with the pills and testosterone combined. There’s still a third who don’t respond, but normalizing their testosterone level has definitely rescued many men who had failed on PDE5 inhibitors.


Hi Douglas, this is a great question, thanks for reaching out. Apart from having a solid training plan that’s suited to your current level of fitness, and goals, you can also use a quality Testosterone Booster which could give you the lift you need to get back into the gym. If you find it difficult to swallow tablets, you can always empty the capsule into a glass of water, juice, or coffee to make it easier to take.
Despite all the wonderful benefits of testosterone boosters, it will only work as well as you are able to make it work. This means that if you’re living a sloppy lifestyle, then your testosterone booster will produce poor results. Testosterone boosters work best when you make small, healthy changes to your lifestyle and diet that will allow your T-booster to give you its full benefits.
Because clomiphene citrate is not approved by the FDA for use in men, little information exists about the long-term effects of taking it (including the risk of developing prostate cancer) or whether it is more effective at boosting testosterone than exogenous formulations. But unlike exogenous testosterone, clomiphene citrate preserves — and possibly enhances — sperm production. That makes drugs like clomiphene citrate one of only a few choices for men with low testosterone who want to father children.
There are a lot of test booster blends out there. A lot of them are junk. I have tried to cover the most effective herbs above. As always, I recommend doing your own research and experiment to see if you notice an effect. If you would like one easy herbal solution I recommend starting with Mike Mahlers Aggressive Strength product purely because I have solid anecdotal evidence of its effectiveness. But again, supplements should be seen purely as that - a supplement to a healthy diet, plenty of sleep, hard training with adequate rest.
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.]
You may be interested in boosting your testosterone levels if your doctor says you have low levels, or hypogonadism, or need testosterone replacement therapy for other conditions. If you have normal testosterone levels, increasing your testosterone levels may not give any additional benefits. The increased benefits mentioned below have only been researched in people with low testosterone levels.

Before a boy is even born, testosterone is working to form male genitals. During puberty, testosterone is responsible for the development of male attributes like a deeper voice, beard, and body hair. It also promotes muscle mass and sex drive. Testosterone production surges during adolescence and peaks in the late teens or early 20s. After age 30, it’s natural for testosterone levels to drop by about one percent each year.
Watch out for ingredients that interfere with blood clotting If you are taking any kind of blood medication, take aspirin or ibuprofen, or have any kind of blood-related condition, you’ll want to consult your doctor before taking any of these supplements. Fenugreek, Forskolin, and Acetyl-L-carnitine are just a few of the ingredients that can make these situations worse and increase your chances of bruising and bleeding.
Thomas M. Gill, MD, Humana Foundation Professor of Medicine at Yale University School of Medicine in New Haven, CT, told EndocrineWeb that these trials were needed because “the pharmaceutical industry did a very good job of promoting testosterone, and there have been suggestions of parallels between age-related decreases in testosterone levels in men, and menopause in older women.”
Hello everyone. First off, thank you Dr. Abraham Morgentaler, for the excellent and refreshing article. I do not intend to spill my guts about symptoms or values on here as it has already been done so many times over. I will say that I am an RN BSN and have been on HRT for going on 6 yrs. I live in Oklahoma and when I first started noticing symptoms I knew something was wrong and began to do research myself. With an initial level of 241 no doctor here at that time, would even consider HRT as I was only 35ish at the time.
My entire presentation was focused on 32 different ways to increase testosterone naturally, with no injections or hormone replacement protocols required. I'm not against bioidentical hormone replacement therapy (BHRT), but I do think one should explore as many natural alternatives as possible first. Or, for even more bang for the buck, pair BHRT with the tactics you'll discover in this episode.

Another study in 2015 by Melville and friends gave subjects either three or six grams of DAA per day for a 14 days (2 weeks). Researchers noted that the 3g dose of D-aspartic acid did not result in any meaningful changes in testosterone levels (or any other anabolic hormones for that matter).[3] However, the group of men receiving 6g per day experienced a significant reduction in both total testosterone and free testosterone levels, with no concurrent change in other hormones tested.[3]

Men who produce more testosterone are more likely to engage in extramarital sex.[55] Testosterone levels do not rely on physical presence of a partner; testosterone levels of men engaging in same-city and long-distance relationships are similar.[54] Physical presence may be required for women who are in relationships for the testosterone–partner interaction, where same-city partnered women have lower testosterone levels than long-distance partnered women.[59]
A4M, which stands for “The American Academy of Anti-Aging Medicine” is dedicated to the advancement of tools, technology, and transformations in healthcare that can detect, treat, and prevent diseases associated with aging. They promote the research of practices and protocols that have the potential to optimize the human aging process. The organization is also dedicated to educating healthcare professionals and practitioners, scientists, and members of the public on biomedical sciences, breakthrough technologies, and medical protocols through our advanced education entity: Metabolic Medical Institute (MMI). Their event in Vegas each year is, in my opinion, well worth checking out.
Testosterone booster supplements are supplements that are used to either increase the amount of testosterone in someone’s body or increase the amount that can be used by the body without being converted into a different type of hormone. While it is a male sex hormone, women also produce some testosterone. People with low testosterone levels and some athletes choose to use testosterone booster supplements to increase their muscle mass, reduce their fat stores, strengthen their bones, and improve their sex drives, particularly as they approach middle age.
Amazing this thread is going after 3 years. Very good indeed. I have low cortisol and my doctor decided to check testosterone. It came back at 5! Not 500, but 5! My doctor did not believe this to be correct. She indicated I would not be able to grow facial hair and that my arm hair would have fell out. She retested. It came back at 23. WTH. So she wanted to start me on Clomid. Well of course my insurance would not cover this. Most pharmacies wanted $300-400 for a 30 day supply. Can’t afford that! The 2 pharmacies that were reasonable cannot get it from their suppliers at this time. So my doctor wants to start weekly injections. I do not know what to think but am trying to find all the information I can on the subject as I am quite nervous. So if anyone else is still reading or comes across this please let me know what you think or your story. it would very much be appreciated. i will be 38 next month and am a little “lost” about all of this. Many thanks! 🙂
   The International Journal of Sports Physiology and Performance recently studied tennis players, rugby teams, and wrestlers to find a link between testosterone and competitive outcome. They found that the difference between winning and losing was reflected in testosterone levels! The athletes' own natural testosterone prior to the game was directly related to the outcome after the game -- the higher the testosterone, the more frequently the athlete won.6
In order to discuss the biochemical diagnosis of hypogonadism it is necessary to outline the usual carriage of testosterone in the blood. Total serum testosterone consists of free testosterone (2%–3%), testosterone bound to sex hormone binding globulin (SHBG) (45%) and testosterone bound to other proteins (mainly albumin −50%) (Dunn et al 1981). Testosterone binds only loosely to albumin and so this testosterone as well as free testosterone is available to tissues and is termed bioavailable testosterone. Testosterone bound to SHBG is tightly bound and is biologically inactive. Bioavailable and free testosterone are known to correlate better than total testosterone with clinical sequelae of androgenization such as bone mineral density and muscle strength (Khosla et al 1998; Roy et al 2002). There is diurnal variation in serum testosterone levels with peak levels seen in the morning following sleep, which can be maintained into the seventh decade (Diver et al 2003). Samples should always be taken in the morning before 11 am to allow for standardization.
