Alterations in mood and depression are a symptom of, but not confined to, hypogonadism.1,6 Outcomes in clinical trials of the effect of testosterone treatment on mood have varied. However, there is evidence that testosterone treatment results in improvements in mood, particularly in older men with hypogonadism.7,8Similarly, although there is an established association between measures of cognitive ability and serum levels of testosterone, the benefits of testosterone treatment on cognition are less clearly established, with some studies reporting improvements in some measures of cognitive function and others failing to detect benefits.6,9-11 Although a potential role for testosterone in protecting cognitive function and preventing Alzheimer’s disease has been proposed by some researchers, confirmation from appropriately-designed clinical trials is awaited.
Bikinis, models, nuts … Is there anything Brazilian that’s not sexy? Selenium is a trace mineral found in Brazil nuts that plays an important role in hormone health. You only need a tiny bit for healthy sperm, but a tiny deficiency can be catastrophic for reproductive health. In one study, men who had lower testosterone and were infertile also had significantly lower selenium levels than the fertile group. Supplementing with the mineral improved chances of successful conception by 56 percent. And a second study that included 69 infertile men with low levels of the mineral, found selenium supplementation could significantly improve sub-par sperm motility associated with testosterone deficiency. Moreover, 11 percent of the men successfully impregnated their partners during the trial!

I think that the importance of testosterone for cardiovascular health is going to be increasingly recognized. In the past, because men die of heart attacks more often than women and men have more testosterone, the fear has been that testosterone causes heart problems. But every single study of whether testosterone is bad for the heart has been negative, and what people haven’t pointed out in most of those negative studies is that there may be a beneficial effect.
Important future developments will include selective androgen receptor modulators (SARMs). These drugs will be able to produce isolated effects of testosterone at androgen receptors. They are likely to become useful clinical drugs, but their initial worth may lie in facilitating research into the relative importance of testosterone’s action at the androgen receptor compared to at other sites or after conversion to other hormones. Testosterone will remain the treatment of choice for late onset hypogonadism for some time to come.
Sergeant Steel is arguably the strongest testosterone booster on the market as it combines 16 effectively dosed ingredients that support testosterone increases and estrogen reduction. It’s not often that you come across a product that combines all of the top ingredients and provides you with their proper dosages. Users have been reporting strong increases in libido, strength, sense of well being, muscle hardness, and improved recovery. If you are looking for a no-holds barred test booster, look no further than Sergeant Steel.

But when a premenopausal woman’s testosterone levels are too high, it can lead to polycystic ovary syndrome (PCOS), a condition that increases the risk of irregular or absent menstrual cycles, infertility, excess hair growth, skin problems, and miscarriage. High levels of testosterone in women, whether caused by PCOS or by another condition, can cause serious health conditions such as insulin resistance, diabetes, high cholesterol, high blood pressure, and heart disease.

Why the difference? The discrepancy in findings between these studies is likely due to the initial training status and base testosterone levels of the subjects. While more research is warranted on this ingredient, D-AA is one of several ingredients suggested to be effective in boosting test levels, especially for older men whose natural testosterone levels have declined due to the natural course of aging.
Ashwagandha: One of the hottest herbs out there right now, this adaptogen packs a one-two punch. First, it helps the body fight off stress: According to one Indian Journal of Psychological Medicine study, ashwagandha has a cortisol-lowering effect—a major benefit to anyone who wants their body to be more T-friendly. And, second, it can also support your T-boosting training efforts. One Journal of the International Society of Sports Nutrition study, for example, found that men who supplemented with ashwagandha saw significantly greater strength and T gains after eight weeks of resistance training than those who took a placebo.
So much to say, take a look at excelmale.com. it is a resource for men like us that give answers, science and dialogue which addresses our questions. It’s a great resource for men like us. Also, I would say to eliminate blue light before bed from tv and pc screens. Simply use blue light blocking glasses or F.lux from the play store. Also get outside in the sun in the AM. The goal is to restore the circadian rhythm which impacts hormone productiion.
I think that the biggest hurdle for most physicians prescribing testosterone is the fear that they’re going to promote prostate cancer. [See “Incongruous findings,” below.] That’s because more than six decades ago, it was shown that if you lowered testosterone in men whose prostate cancer had metastasized, their condition improved. (It became a standard therapy that we still use today for men with advanced prostate cancer. We call it androgen deprivation or androgen-suppressive therapy.) The thinking became that if lowering testosterone makes prostate cancer disappear, at least for a while, then raising it must make prostate cancer grow. But even though it’s been a widely held belief for six decades, no one has found any additional evidence to support the theory.
For the 3rd year in a row, DAA Max claims the #1 spot in the Top 10. A product that stands out in all categories with a formula that has been shown in studies to increase free testosterone levels after just 12 days of consistent use. DAA Max’s feedback over the years has shown that this product is not only potent in terms of elevating testosterone and boosting one’s libido, but at its low price it just can’t be beaten.
Sexual arousal - boosting testosterone can improve sexual arousal, even if you have normal testosterone levels. Higher levels of testosterone can make it easier for you to get aroused and can boost your sex drive generally. While this doesn’t affect the physical action of your erections, if you are not getting hard because you’re not aroused then boosting testosterone could help.
Tongkat ali (a.k.a. Longjack, a.k.a. Eurycoma Longifolia) is a foundational compound of Ayurveda, commonly used as an aphrodisiac. Similar to DHEA, longjack has been found to be effective in both men and women for improving libido, total and free testosterone concentrations as well as muscle mass and strength in men and women! And, unlike many of the other old world herbs commonly touted as natural testosterone boosters, longjack actually has a fair amount of human research denoting its benefits.
The researchers found that men who received hormone treatment experienced an increase in bone strength and density. Strength increases were greater in the spine than they were in the hip. However, as with other T Trials, more research needs to be done. A larger study over many years would need to be performed to determine whether testosterone could decrease risk of bone fracture.
Male sex characteristics greatly depend on testosterone synthesis in your body. If you keep the levels of this hormone normal, you will prevent sexual potency issues. Accordingly, the elevation of testosterone levels helps combat the impairment of erectile function. The levels of this hormone also affect male fertility. If these levels grow, fertility improves. Aging has a negative impact on testosterone secretion. Such hormonal imbalance is inevitable and permanent. But it’s still possible to positively change the situation and stimulate hormone production by using the high-quality testosterone boosters.
The results of these studies indicate that testosterone treatment in older men with low testosterone may proffer some benefits. However, testosterone treatments may also entail risks. The exact trade-off is unknown. Larger and longer studies need to be performed to clarify the effects of testosterone on heart health, bone health, disability, and more.
I think we’ll also find out in five years that there very well may be general health benefits of having normal testosterone compared to low testosterone. There are growing data for all-cause mortality that men who have low testosterone die earlier than those who have normal testosterone. A study by the Veterans Administration reported about a year ago showed low testosterone levels were associated with a dramatically increased mortality rate. It’s hard to know why that is, but I think we’ll be focused on that in the coming years.
“However, the parallels don’t necessarily follow logically, creating a real need to bring more evidence to this area so that physicians and patients would be able to make more  informed decisions based on the best possible evidence,” said Dr. Gill, a professor of medicine and the lead investigator at the Yale study site, the largest site participating in the TTrials, and coauthor of all 4 TTrials. 

This has become a common practice despite an Institute of Medicine (IOM) report issued in 2003, indicating insufficient evidence of any benefit derived from testosterone hormone therapy to address expected symptoms of male aging.4  These studies, and 2 others (to be presented in a separate EW research brief) come on the heels of research on the efficacy of prescribing testosterone5 that appeared in the NEJM last year.

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.)
Why do we need magnesium? Magnesium is an essential nutrient in the body that can help decrease the risk of developing osteoporosis, improve insulin sensitivity, and lower the risk of hypertension. This article looks at other health benefits of magnesium, what happens if a person has a deficiency, supplements, and how to include it in the diet. Read now
This study [9] also reported significantly increased glutathione levels. Glutathion has been shown to have a synergetic effect with l-citrulline as their combination further increases nitrate and nitrite levels and contributes to the sustained release of NO. While some previous studies have indicated that glutathione stimulates L-arginine turnover and increases nitric oxide synthase (NOS).
Other side effects include increased risk of heart problems in older men with poor mobility, according to a 2009 study at Boston Medical Center. A 2017 study published in JAMA found that treatments increase coronary artery plaque volume. Additionally, the Food and Drug Administration (FDA) requires manufactures to include a notice on the labeling that states taking testosterone treatments can lead to possible increased risk of heart attacks and strokes. The FDA recommends that patients using testosterone should seek medical attention right away if they have these symptoms:
Men who take Testosterone report a surge in their sex drive and frequency of sex. They are better able to work out, build muscle mass and strength. The fat around their belly melts away as they lose weight and trim their waists. Men who enroll in a comprehensive Testosterone Replacement program which includes diet, nutrition and exercise - feel better, sleep better and look better. They have their edge back along with a restored enthusiasm for daily living, pursuing relationships and living life.
Mental status changes including excess aggression are a well known phenomenon in the context of anabolic steroid abuse (Perry et al 1990). An increase in self-reported aggressive behaviors have also been reported in one double blind placebo controlled trial of testosterone in young hypogonadal men (Finkelstein et al 1997), but this has not been confirmed in other studies (Skakkebaek et al 1981; O’Connor et al 2002). Aggression should therefore be monitored but in our experience is rarely a significant problem during testosterone replacement producing physiological levels.

Aromatase inhibitors can boost testosterone on their own, but they can also complement other testosterone boosters. If you take a supplement that increases testosterone without inhibiting the aromatase enzyme (through hypothalamic stimulation, for instance), you may find yourself with more estradiol than you need, a situation that taking an aromatase inhibitor may remedy.

Magnesium comes with a strict upper cap. Excess magnesium is hard on your kidneys, and can lead to kidney failure. The NIH recommends that men consume 400-420 mg of magnesium daily, but that they should not exceed 350 mg of supplemental magnesium per day. Because while it’s rare for people to chronically overdose on magnesium through diet (you’d have to eat a lot of almonds and spinach, for example), overdose by supplement is far more common.

A sedentary lifestyle is another scourge for modern civilization. And this is a serious danger for men. After all, if physical activity is minimal, the testosterone levels will decrease steadily. And in this situation, strength training exercises are a proven method for raising testosterone. Thus, sports exercises always helped raise the levels of male sex hormone. As a result, the testosterone levels elevate after every workout.


Grape seed extract is another ingredient with not enough research to suggest a dosage. Grape seed extract can interact with drugs like “blood thinners, NSAID painkillers (like aspirin, Advil, and Aleve), certain heart medicines, cancer treatments, and others.” If this sounds like you (or if you ever pop an Advil to clear off a headache), you’ll need to speak with a doctor to make sure this supplement is safe to take.
“Poor lifestyle can mimic the symptoms of low testosterone and can actually cause low testosterone as well,” says Hodzovic. “The main culprits include lack of sleep, excessive stress, too little or too much exercise and too little or too much body fat. Getting healthy and active and eating a balanced nutritious diet along with enough sleep are the most important things to do.
Low testosterone levels may contribute to decreased sex drive, erectile dysfunction, fragile bones, and other health issues. Having low testosterone levels may also indicate an underlying medical condition. See your doctor if you suspect you have low testosterone. A simple blood test is all it takes to check if your testosterone falls within the normal range.
The regular intake of testosterone boosters is known for the high level of safety comparing to the hormone injections and the use of illegal steroids. But still to protect yourself against any possible adverse reactions, you should remember that the supplementation can’t be continuous. The breaks from time to time are required. Such an approach to the use of boosters is healthy and best-working if you aspire to enhance own hormone production without any harm.
Every vitamin, mineral, and ingredient that affects the human body can be taken in enough quantities that they are harmful, or toxic, even the ones that — at lower levels — are beneficial or necessary. Unfortunately, testosterone boosters contain a lot of ingredients that are not well understood. This means in addition to not being able to confirm whether certain ingredients increase testosterone, the scientific and medical communities also don’t know at what levels many ingredients become toxic. On the up side, you might need to eat several pounds of a particular leafy plant before it becomes harmful. On the down side, it could be significantly less that pushes you over your body’s limit. We simply don’t know how little or how much the human body can tolerate. We recommend keeping your doctor in the loop when you add any supplement with unproven ingredients into your diet — they’ll be able to help you find and track any undesired side-effects that these ingredients might cause.
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.

Zinc deficiency also negatively affects testosterone levels, according a 2014 article in the Journal of Plant Biochemistry and Physiology. The authors of this review note that zinc supplementation can increase circulating testosterone in some populations. In fact, daily supplementation with typical doses may double testosterone within a few months.
My favorite overall tool to manage stress is EFT (Emotional Freedom Technique), which is like acupuncture without the needles. It's a handy, free tool for unloading emotional baggage quickly and painlessly, and so easy that even children can learn it. Other common stress-reduction tools with a high success rate include prayer, meditation, laughter and yoga, for example. Learning relaxation skills, such as deep breathing and positive visualization, which is the "language" of the subconscious.

If you’re an older man with low testosterone and interested in taking testosterone, this decision should be carefully considered with your physician. Your physician will be able to better assess the balance of your conditions and whether hormone replacement could put you at potential risk. It's a bad idea for anybody to engage in hormone supplementation without the supervision of a physician. Just because hormones occur naturally in the body does not mean that they can be taken without negative effects.

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.
55+ million men in america between 40 and 70 years of age is a large enough group to warrant interest in a thorough study of the aged male delivery system and other sex related issues. There is a good chance there are 55 million women out there wishing for some kind of help also. Those are significant numbers, about 1/3 of the total population and the lions share of the income producers. And the best the medical community can do is speculate at the real cause for a significant cancer? Perhaps prostate cancer is the real cause of global warming, there is no real science unless there is a real paycheck?
Bisphenol-A also known under the name of BPA is a chemical compound which is very widespread for manufacturing a wide spectrum of plastic items and aluminum cans. Many studies have already proven the fact that even the smallest amount of BPA is very harmful to the human health. This compound causes hormonal imbalance and even may lead to prostate cancer.
Benefits: Maca roots originates from the mountains of Peru. For a long time, natives have been using Maca roots as not only a food supply but for it’s properties for increasing sexual potency. It has been prove to improve erectile dysfunctions, libido and sperm production. Maca roots stimulate semen volume, sperm count and sperm motility, which makes Maca a powerful Aphrodisiac.

Two of the immediate metabolites of testosterone, 5α-DHT and estradiol, are biologically important and can be formed both in the liver and in extrahepatic tissues.[155] Approximately 5 to 7% of testosterone is converted by 5α-reductase into 5α-DHT, with circulating levels of 5α-DHT about 10% of those of testosterone, and approximately 0.3% of testosterone is converted into estradiol by aromatase.[2][155][161][162] 5α-Reductase is highly expressed in the male reproductive organs (including the prostate gland, seminal vesicles, and epididymides),[163] skin, hair follicles, and brain[164] and aromatase is highly expressed in adipose tissue, bone, and the brain.[165][166] As much as 90% of testosterone is converted into 5α-DHT in so-called androgenic tissues with high 5α-reductase expression,[156] and due to the several-fold greater potency of 5α-DHT as an AR agonist relative to testosterone,[167] it has been estimated that the effects of testosterone are potentiated 2- to 3-fold in such tissues.[168]


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.
There are studies that show Soy consumption in humans leads to lower sperm count, but unfortunately they did not look at testosterone levels in the study (40). This (41) particular study compared the estrogen production of men drinking soy protein to those drinking whey. After two weeks they found the estradiol levels were equal, however soy drinkers had LOWER Testosterone levels and HIGHER cortisol levels (both bad).
Hypogonadism is highly prevalent amongst men with diabetes mellitus type 2 or symptoms of the metabolic syndrome, including insulin resistance, impaired glucose regulation, obesity, and hypertension.1,6,13,14,17,18 Low testosterone in many men with diabetes remains undiagnosed and untreated, and current guidelines recommend measurement of testosterone levels in such patients and, equally, that such chronic diseases should be investigated and treated in men with hypogonadism.1,6 It is not yet fully known whether diabetes is a cause or a consequence of low testosterone, and the full effects of testosterone administration on glycemic control in hypogonadal men with diabetes are unclear. However, there are indications that treating hypogonadism may have benefits on metabolic status in men with diabetes, and there is evidence that testosterone replacement therapy has a beneficial effect on risk factors for diabetes such as central obesity, insulin sensitivity, glucose control and blood lipid profiles in hypogonadal men with type 2 diabetes.14,19,20
Testosterone fluctuates according to age and life circumstance, often plummeting at the onset of parenthood, and spiking (for some) during moments of triumph. Romantic relationships, too, can impact a person’s testosterone production; though the reasons are still not fully understood, entering a relationship tends to increase women’s testosterone levels, while decreasing men’s. Since males produce significantly more testosterone than females—about 20 times more each day—females can be more sensitive to these fluctuations. High levels of testosterone, particularly in men, have been correlated with a greater likelihood of getting divorced or engaging in extramarital affairs, though a causal link has not been established.
Testosterone may strengthen your heart. Research on testosterone’s relation to heart health is split. Some scientists have found that men with higher testosterone levels have an increased risk of heart disease, while recent studies have shown that men with below-normal T levels are more at risk for heart problems. The research is still on-going, but many doctors find the evidence compelling that optimal testosterone levels can help prevent cardiovascular disease.
Hypogonadism is highly prevalent amongst men with diabetes mellitus type 2 or symptoms of the metabolic syndrome, including insulin resistance, impaired glucose regulation, obesity, and hypertension.1,6,13,14,17,18 Low testosterone in many men with diabetes remains undiagnosed and untreated, and current guidelines recommend measurement of testosterone levels in such patients and, equally, that such chronic diseases should be investigated and treated in men with hypogonadism.1,6 It is not yet fully known whether diabetes is a cause or a consequence of low testosterone, and the full effects of testosterone administration on glycemic control in hypogonadal men with diabetes are unclear.

If a man's testosterone looks below the normal range, there is a good chance he could end up on hormone supplements—often indefinitely. "There is a bit of a testosterone trap," Dr. Pallais says. "Men get started on testosterone replacement and they feel better, but then it's hard to come off of it. On treatment, the body stops making testosterone. Men can often feel a big difference when they stop therapy because their body's testosterone production has not yet recovered."
