Dr. Fugh-Berman said these campaigns encourage men to "ask your doctor" whether their weight gain, falling asleep after dinner, reduced energy, and diminished sex drive are due to "Low T." At the same time, the companies are working other angles to influence doctors' prescribing practices through industry-sponsored continuing medical education (CME) courses and sponsored medical journal articles. They have even created a respectable-sounding journal called The Aging Male. Fugh-Berman said all these channels "are being used to persuade doctors they should be treating this."

So if you’re intent on maximizing your testosterone levels, and/or you have applied all of the above and you’re still not satisfied with your results (which would be surprising) then you could try the below. I will point out that some of these tips may not have the scientific evidence to back them up like the previous points, but I can assure you that either I have or do use them (and have positive results), or a client has used them with pleasing results, or finally it is such a new conception that there isn’t enough evidence to prove it one way or another.


The participants were seen every 4 weeks. Blood was taken to measure hormone levels, and questionnaires were given to assess physical function, health status, vitality, and sexual function. Body fat and muscle measurements were also taken at the beginning and end of the 16 weeks. The study was funded in part by NIH’s National Institute on Aging (NIA) and National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK). Results appeared in the September 12, 2013, issue of the New England Journal of Medicine.
However, testosterone is only one of many factors that aid in adequate erections. Research is inconclusive regarding the role of testosterone replacement in the treatment of erectile dysfunction. In a review of studies that looked at the benefit of testosterone in men with erection difficulties, showed no improvement with testosterone treatment. Many times, other health problems play a role in erectile difficulties. These can include:
Before taking any supplements, at either end of the spectrum, you need to check whether it’s low testosterone that is actually causing the problem. Taking something that you don’t need could potentially cause irreversible issues. For that reason, steroid hormones like DHEA should never be prescribed without having blood tests first. Roked also recommends regular blood monitoring to make sure you’re taking the correct dosage.

Testosterone insufficiency has been associated with HIV infection in men (Dobs et al 1988). Early reports suggested that testosterone therapy may have an ameliorating effect on both depression and decreased energy in HIV infected men, even if testosterone levels were not reduced (Rabkin et al 1999; Grinspoon et al 2000; Rabkin et al 2000). Both depression and fatigue, however, are common features of HIV-positive men and may be associated with factors other than reduced levels of testosterone. The disease itself may induce depression and fatigue may be a consequence of the disease, per se, or of some of the medications used to control HIV.
On review of the patient’s history, he was found to have undergone laboratory tests before starting to use the aforementioned testosterone booster product. All blood parameters (testosterone hormone and full chemical profile) before product intake were in the normal range. A physical examination that included blood pressure and pulse assessments showed nothing out of the ordinary, and the man appeared to be in good condition before product consumption. After that medical checkup, the athlete began to consume the product for 42 continuous days divided into 2 cycles (each cycle comprised 24 days). The daily dose was a single pack of Universal Nutrition Animal Stak (ingredients are listed in Table 1), following the exact direction of the manufacturing company hoping to get the best results.
Testosterone is significantly correlated with aggression and competitive behaviour and is directly facilitated by the latter. There are two theories on the role of testosterone in aggression and competition.[77] The first one is the challenge hypothesis which states that testosterone would increase during puberty thus facilitating reproductive and competitive behaviour which would include aggression.[77] Thus it is the challenge of competition among males of the species that facilitates aggression and violence.[77] Studies conducted have found direct correlation between testosterone and dominance especially among the most violent criminals in prison who had the highest testosterone levels.[77] The same research also found fathers (those outside competitive environments) had the lowest testosterone levels compared to other males.[77]
Do low levels of testosterone produce symptoms in middle-aged men? Absolutely. In fact, the classic symptoms were first recognized more than 70 years ago when two American physicians, Carl Heller, MD, and Gordon Myers, MD, showed the effectiveness of testosterone treatment for symptoms of fatigue, depression, irritability, low sex drive, erectile dysfunction, night sweats, and hot flashes in men. Over the years, subsequent studies have found that some—but not all—men with low, age-adjusted testosterone levels exhibit symptoms consistent with andropause. All experience improvement with testosterone therapy.

You should also know that a lot of people are deficient in Vitamin D. In the USA & many other western regions in the world, vitamin D deficiency is at epidemic proportions. The best way to increase your D levels is sun exposure. You only need 20-30 minutes of exposure to a large amount of skin (i.e., take your shirt off and go for a walk during the day).
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.
Dr. Wassersug, whose background is in evolutionary biology, also noted that lower testosterone in older men may be adaptive, a positive benefit, as our bodies age and become increasingly frail. "The argument can be made," he said, "that it's not beneficial to have the mindset of a 19-year-old when you are 49-years-old, because if you are aggressive enough to get into a conflict with an actual 19-year-old, you are going to get killed."
Testosterone makes a contribution to nitric oxide formation. Nitric oxide, released from penile nerves stimulates guanylate cyclase which catalyzes the transformation of guanosine-5-triphosphate into 3′,5′-cyclic, guanosine monophosphate (cyclic GMP). Gyclic GMP causes vasodilatation and hence erection formation (Morelli et al 2005). The breakdown of cyclic GMP to GMP is mediated by the enzyme, phosphodiesterase type-5, the inhibitors of which (eg, sildenafil citrate) enhance erection formation and maintanence (Carson and Lue 2005).
All the active substances available in TestoGen are fully natural. And their efficacy and safety is science-backed. So, if you don’t have individual sensitivity to the supplement ingredients and purchase the product directly from the manufacturer instead of purchasing from unknown suppliers, the likelihood of side effects during the supplementation is minimal. And the customer feedback proves this.
These results have been echoed in clinical trials. A meta-analysis of 24 RCTs looked at weight loss caused by diet or bariatric surgery:[22] In the diet studies, the average 9.8% weight loss was linked to a testosterone increase of 2.9 nmol/L (84 ng/dL). In the bariatric-surgery studies, the average 32% weight loss was linked to a testosterone increase of 8.7 nmol/L (251 ng/dL).
Research is always highlighting the dangers of long-term stress, which can elevate levels of the hormone cortisol. Unnatural elevations in cortisol can quickly reduce testosterone. These hormones work in a seesaw-like manner: as one goes up, the other comes down. Stress and high cortisol can also increase food intake, weight gain and the storage of harmful body fat around your organs. In turn, these changes may negatively impact your testosterone levels. For both optimal health and hormone levels, you should try to reduce repetitive stressful situations in your life. Focus on a diet based on whole foods, regular exercise, good sleep, laughter and a balanced lifestyle, all of which can reduce stress and improve your health and testosterone levels.
It is now well-established that elderly men with type 2 diabetes mellitus have reduced levels of testosterone (Barrett-Connor 1992; Betancourt-Albrecht and Cunningham 2003). It is known, however, that obese men and diabetic men have reduced levels of SHBG (Barrett-Connor 1990) which could account for the lower total testosterone levels found in diabetic men. Dhindsa et al (2004) studied 103 male patients who had type 2 diabetes mellitus using free testosterone (done by equilibrium dialysis) or calculated free testosterone which takes SHBG levels into account. Of the 103 patients, 57 had free testosterone by equilibrium dialysis and of these, 14 (25%) had a free T below 0.174 nmol/L and were considered hypogonadal. Using a total testosterone of 10.4 nmol/L (300ng/dl) as the lower limit of normal 45 patients (43%) were in the hypogonadal range. They also found that LH and FSH concentrations were significantly lower in the hypogonadal group. The authors thus concluded that hypogonadotropic hypogonadism was a common finding in type 2 diabetes irrespective of glycemic control, duration of disease or the presence of complications of diabetes or obesity.
We’ll be honest. Testosterone boosters don’t really boost. The best testosterone booster is like taking a multivitamin with extra herbs that might slightly and temporarily increase your testosterone levels. Like all supplements, finding the right testosterone booster means wading into a sea of ingredients, all promising to help. Of 133 testosterone boosters, we found only one with the right ingredients to help raise your testosterone levels: Beast Sports Nutrition - Super Test ($45.88 for 180 capsules, or $2.04 per day).

Remember that each person is unique, and each body responds differently to treatment. TT may help erectile function, low sex drive, bone marrow density, anemia, lean body mass, and/or symptoms of depression. However, there is no strong evidence that TT will help memory recall, measures of diabetes, energy, tiredness, lipid profiles, or quality of life.


As you cut these dietary troublemakers from your meals, you need to replace them with healthy substitutes like vegetables and healthy fats (including natural saturated fats!). Your body prefers the carbohydrates in micronutrient-dense vegetables rather than grains and sugars because it slows the conversion to simple sugars like glucose, and decreases your insulin level. When you cut grains and sugar from your meals, you typically will need to radically increase the amount of vegetables you eat, as well as make sure you are also consuming protein and healthy fats regularly.
Epidemiological studies suggest that many significant clinical findings and important disease states are linked to low testosterone levels. These include osteoporosis (Campion and Maricic 2003), Alzheimer’s disease (Moffat et al 2004), frailty, obesity (Svartberg, von Muhlen, Sundsfjord et al 2004), diabetes (Barrett-Connor 1992), hypercholesterolemia (Haffner et al 1993; Van Pottelbergh et al 2003), hypertension (Phillips et al 1993), cardiac failure (Tappler and Katz 1979; Kontoleon et al 2003) and ischemic heart disease (Barrett-Connor and Khaw 1988). The extent to which testosterone deficiency is involved in the pathogenesis of these conditions, or to which testosterone supplementation could be useful in their treatment is an area of great interest with many unanswered questions.
Your body’s circadian rhythm essentially resets itself every night and releases chemicals like cortisol, which contribute to the overall hormone balance that can prevent low T-levels. I have even heard one endocrinologist claim that one hour of sleep between 10 p.m. and 2 a.m. has the same healing effects on your body as two hours of sleep before or after this timeslot!
Recently, a panel with cooperation from international andrology and urology societies, published specific recommendations with regard to the diagnosis of Late-onset Hypogonadism (Nieschlag et al 2005). These are summarized in the following text. It is advised that at least two serum testosterone measurements, taken before 11 am on different mornings, are necessary to confirm the diagnosis. The second sample should also include measurement of gonadotrophin and prolactin levels, which may indicate the need for further investigations for pituitary disease. Patients with serum total testosterone consistently below 8 nmol/l invariably demonstrate the clinical syndrome of hypogonadism and are likely to benefit from treatment. Patients with serum total testosterone in the range 8–12 nmol/l often have symptoms attributable to hypogonadism and it may be decided to offer either a clinical trial of testosterone treatment or to make further efforts to define serum bioavailable or free testosterone and then reconsider treatment. Patients with serum total testosterone persistently above 12 nmol/l do not have hypogonadism and symptoms are likely to be due to other disease states or ageing per se so testosterone treatment is not indicated.
Testosterone is a male hormone. Hormones are chemical messengers that are secreted by the brain directly into the blood, which carries them to organs and tissues of the body to perform their functions. Testosterone is produced by the testicles, two oval organs that produce sperm in men. Dietary supplements help with increasing the levels of hormones if we have low levels in the body. In men, testosterone plays a key role in the development of male reproductive organs. In addition, it helps with increasing muscle mass, bone mass, and the growth of body hair. It is also good for general health and well-being. It also prevents loss of bone mass and density. Testosterone also helps maintain the sex drive and energy levels. Moreover, it helps with production of sperm and red blood cells. Testosterone levels start to fall with age. As a result, some men who have low testosterone levels may benefit from testosterone prescribed by their doctor. Testosterone booster supplements may also help.
The effects of testosterone in humans and other vertebrates occur by way of multiple mechanisms: by activation of the androgen receptor (directly or as DHT), and by conversion to estradiol and activation of certain estrogen receptors.[109][110] Androgens such as testosterone have also been found to bind to and activate membrane androgen receptors.[111][112][113]

Alcohol should be avoided when trying to increase testosterone levels. Healthy normal men, consuming reasonable amounts of alcoholic drink, experience a 20% drop in their serum levels of testosterone. In chronic alcoholics with extensive liver damage those levels can be reduced by as much as 50% and they can become feminized (loose facial and pubic hair, become impotent, and fat deposits behind the nipples that give the appearance of breasts).

Vitamin D is arguably the most important vitamin when it comes to testosterone. A study published in the Journal of Clinical Endocrinology examined the relationship between vitamin D supplementation and testosterone levels in men. The authors found that participants with higher levels of vitamin D had significantly higher levels of free testosterone compared to those with insufficient levels of vitamin D.8 Based on these study results, it appears vitamin D has a strong relationship with testosterone levels.

Great article with a lot of useful information. I completely agree with your top three picks. I have done a ton of research as well. Currently I am taking Testogen for over two months and it has worked for me. It has double my low T and I am 61 years old. I do feel better and have more energy. Even have morning wood sometimes and haven’t for a long time.
Because of inconclusive or conflicting results of testosterone treatment studies reported in the literature, Rabkin and colleagues (2004) undertook a comparison study among testosterone, the anti-depressant, fluoxetine, and placebo in eugonadal HIV positive men. They found that neither fluoxetine nor testosterone were different from placebo in reducing depression, but that testosterone did have a statistically significant effect in reducing fatigue. It is note-worthy that fatigue was reduced with testosterone treatment even though virtually all the men in the study had testosterone levels within the reference range.
The researchers found that the dose of testosterone required to produce different effects in the body varied widely. The influence of testosterone and estradiol also differed. As the testosterone gel dose was reduced, the scientists showed, reductions in lean mass, muscle size, and leg-press strength resulted from decreases in testosterone itself. In contrast, increases in body fat were due to the related declines in estradiol. Both testosterone and estradiol levels were associated with libido and erectile function.
We required all of our testosterone boosters to have magnesium, but gave preference to magnesium aspartate, citrate, lactate, and chloride. These forms have been found to be more easily absorbed than magnesium oxide and sulfate. (On the other hand, it didn’t count if the supplement had magnesium stearate, which is used to make pills not stick together.)
Few of the most often asked questions I get are: what do I eat to maintain high testosterone levels, and if I have a specific list of recommended foods that increase testosterone naturally. While there are many food related posts scattered around this blog, I’ve never really made an all-around post about what I would put into a high T pantry. Until now.
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.
Although the benefits of multivitamins are hotly debated, specific vitamins and minerals may be beneficial. In one study, zinc and vitamin B supplements increased sperm quality by 74%. Zinc also boosts testosterone in athletes and those who are deficient in zinc. Other studies also suggest vitamins A, C and E can play a role in your sex hormone and testosterone levels, although more research is needed. Out of all the vitamins and minerals available, the research on testosterone shows vitamin D and zinc supplements may be best.
Did you know that a meat-free diet can lower your T-levels by 14%? When your body lacks protein, it boosts the production of other hormones that deactivate testosterone. However, on the other hand, it has been found that a diet that is excessively rich in saturated fats found in meats like beef and lamb can also lower T-levels. Venison is the middle ground and is also excellent for muscle growth.
We reviewed the ingredient lists of our supplements and cut three that prescribed us an overdose of magnesium. While it’s possible to stay under the 350mg daily limit of supplemental magnesium by taking fewer pills than the manufacturer recommends, we were concerned that any manufacturer would advise you to exceed the recommended safety limit for magnesium intake by almost a third.

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.
The brain is also affected by this sexual differentiation;[13] the enzyme aromatase converts testosterone into estradiol that is responsible for masculinization of the brain in male mice. In humans, masculinization of the fetal brain appears, by observation of gender preference in patients with congenital diseases of androgen formation or androgen receptor function, to be associated with functional androgen receptors.[95]
D-Aspartic acid is a natural amino acid involved in the synthesis and release of testosterone, which research shows can be used as a testosterone booster for infertile men. One 90-day study gave D-Aspartic acid to men with impaired sperm production, and found their sperm count rose from 8.2 million sperm per ml to 16.5 million sperm per ml, more than a 100 per cent increase.
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:
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.
“This study establishes testosterone levels at which various physiological functions start to become impaired, which may help provide a rationale for determining which men should be treated with testosterone supplements,” Finkelstein says. “But the biggest surprise was that some of the symptoms routinely attributed to testosterone deficiency are actually partially or almost exclusively caused by the decline in estrogens that is an inseparable result of lower testosterone levels.”
Testosterone is only one of many factors that influence aggression and the effects of previous experience and environmental stimuli have been found to correlate more strongly. A few studies indicate that the testosterone derivative estradiol (one form of estrogen) might play an important role in male aggression.[66][67][68][69] Studies have also found that testosterone facilitates aggression by modulating vasopressin receptors in the hypothalamus.[70]
As we age, the body undergoes multiple degenerative changes at multiple sites and in multiple systems. The changes of aging are inevitable and inexorable and represent the march toward ultimate death. We are mortal beings whose destiny it is to die. As we come to learn about the processes of life we can better prepare ourselves for the finality of death and on the way perhaps retard the degenerative process, or repair it (for however long we may enjoy this repair), or substitute chemical compounds that our bodies once produced in abundance, an abundance which fades with the advance of age.
Similar to the cruciferous veggies, you can also use coconut oil in many ways. You could use it as a cooking medium or for those light oil brushes for baking sessions. You can change the butter with coconut oil for that bowl of popcorn on movie night. Seeing the link between coconut oil and testosterone, it would be an error not to put it in your diet.
"The hope," explained Dr. Swerdloff in a telephone interview, "is this will provide some clarity as to whether testosterone replacement therapy will benefit men in this older age group who clearly have abnormal testosterone and have some symptoms." He added, "We don't know whether it will be beneficial at all the endpoints we are studying, or be beneficial to some and not others. We don't know if the benefits occur at different blood levels that are attained in the individuals."
Sprinting has been shown numerous times that it has positive effects on testosterone levels. One 2011 study (ref 84) looked at weightlifters who performed 4x35m sprints twice a week. In contrast to the control group (who continued lifting but did not sprint), it was found that “After the 4-week training program, total testosterone and the total testosterone/cortisol ratio increased significantly in the (sprinters) EXP group”.
Eggs are among the foods to increase testosterone. A healthy breakfast at the start of the day is the most crucial meal of the day. It makes your body jumpstart for all the work that lies ahead. To increase your testosterone level, there is no better meal to utilize than the morning breakfast. Eggs, the main part of any good breakfast, are a great way to boost your T-Levels.

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.

In the hepatic 17-ketosteroid pathway of testosterone metabolism, testosterone is converted in the liver by 5α-reductase and 5β-reductase into 5α-DHT and the inactive 5β-DHT, respectively.[1][151] Then, 5α-DHT and 5β-DHT are converted by 3α-HSD into 3α-androstanediol and 3α-etiocholanediol, respectively.[1][151] Subsequently, 3α-androstanediol and 3α-etiocholanediol are converted by 17β-HSD into androsterone and etiocholanolone, which is followed by their conjugation and excretion.[1][151] 3β-Androstanediol and 3β-etiocholanediol can also be formed in this pathway when 5α-DHT and 5β-DHT are acted upon by 3β-HSD instead of 3α-HSD, respectively, and they can then be transformed into epiandrosterone and epietiocholanolone, respectively.[153][154] A small portion of approximately 3% of testosterone is reversibly converted in the liver into androstenedione by 17β-HSD.[152]


“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.

Testosterone is significantly correlated with aggression and competitive behaviour and is directly facilitated by the latter. There are two theories on the role of testosterone in aggression and competition.[77] The first one is the challenge hypothesis which states that testosterone would increase during puberty thus facilitating reproductive and competitive behaviour which would include aggression.[77] Thus it is the challenge of competition among males of the species that facilitates aggression and violence.[77] Studies conducted have found direct correlation between testosterone and dominance especially among the most violent criminals in prison who had the highest testosterone levels.[77] The same research also found fathers (those outside competitive environments) had the lowest testosterone levels compared to other males.[77]
Common side effects from testosterone medication include acne, swelling, and breast enlargement in males.[10] Serious side effects may include liver toxicity, heart disease, and behavioral changes.[10] Women and children who are exposed may develop virilization.[10] It is recommended that individuals with prostate cancer not use the medication.[10] It can cause harm if used during pregnancy or breastfeeding.[10]

Although, most studies on TT have been conducted on animals, the results appear promising. One study that looked at sexually sluggish male albino rats found that having been given extracts of TT, the rats "mount frequency, intromission frequency, and penile erection index" all increased, while "mount latency, intromission latency, and ejaculatory latency" all decreased. Who said romance was dead?


The biggest problem with supplementing your testosterone levels is it can shut off your own natural production and it can also permanently lower your sperm count. Taking testosterone boosters may also leave you open to some of the other unwanted side effects, like acne, male pattern baldness, mood swings and aggressive behaviour. To give yourself the best possible chance of avoiding these side effects, you need to see an expert before going for boosters.
Dr. Anthony's Notes: I like Tribulus. It is a VERY common herb in almost all testosterone boosting products – again though, it may be more of a libido enhancer than anything. From my personal experience, it's effective when stacked with the other libido enhancing supplements in this guide. How To Take Tribulus: Take 200-400mg once per day of a 45-60% saponin extract product.
Like other supplements and medication, testosterone therapy comes with risks and possible side effects. This is particularly true if you try to take it for normal aging rather than for treatment of a condition. Also, the Cleveland Clinic points out that the effects that these supplements may have on your heart and prostate can lead to a number of potential issues. Complications include:

Nearly 1 out of every 4 men over age 50 experience the pain of losing the ability to perform sexually as a result of erectile dysfunction (ED). Common causes of ED are atherosclerosis, diabetes, prescription drug use (namely high blood pressure, depression, and allergy drugs), and—you guessed it—low testosterone. Supplements that may help include the following:
