However, some of these signs and symptoms can be caused by factors other than low testosterone, including medication side effects, thyroid problems, depression and excessive alcohol use. There are also conditions, such as obstructive sleep apnea, that might affect testosterone levels. Once these conditions are identified and treated, testosterone typically will return to a normal level.

With the decline of ovarian function in menopause, not only do estrogen levels decline, but so does testosterone availability, since the ovaries contribute, either by direct secretion or through precursor production, about 50 percent of circulating testosterone. The other 50 percent is supplied by the adrenal glands. Many post-menopausal or oophorectomized women are symptomatic as a consequence of reduced testosterone, the leading symptom being loss of libido (Sherwin and Gelfand 1987; Simon et al 2005). There is an increasing trend toward testosterone supplementation in these women. Such supplementation may also lead, not only to increased libido, but to increased bone mineral density and an improvement in general overall sense of well-being including energy, strength, motivation and mood (Davis et al 1995; Davis et al 2000).
The hypogonadal-obesity-adipocytokine cycle hypothesis. Adipose tissue contains the enzyme aromatase which metabolises testosterone to oestrogen. This results in reduced testosterone levels, which increase the action of lipoprotein lipase and increase fat mass, thus increasing aromatisation of testosterone and completing the cycle. Visceral fat also promotes lower testosterone levels by reducing pituitary LH pulse amplitude via leptin and/or other factors. In vitro studies have shown that leptin also inhibits testosterone production directly at the testes. Visceral adiposity could also provide the link between testosterone and insulin resistance (Jones 2007).

Now men everywhere are wondering what it was about this testosterone supplement that made the Sharks want to invest so much in it. Does it really work? It turns out, the Kim sisters have created a whole new chemical compound that boosts testosterone production in men. It is especially effective for men over 40 years old, which is the average age that testosterone begins to naturally diminish. There are plenty of supplements and other products on the market that promise to increase testosterone production in aging men, but very few of them deliver significant results…if any at all. What sets the Kim sisters' product apart from the rest is that it contains the first reuptake inhibitor, which makes it highly effective in boosting testosterone production and effectively curing things like erectile dysfunction.

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."
We kept it simple, and followed the premise of testosterone boosters: testosterone affects muscle gain, weight loss, and libido, so by increasing the amount of testosterone in the body, we can improve on each of those goals. This meant that we looked for ingredients proven to increase testosterone levels, not ingredients that might increase libido or help build muscle mass independently of testosterone (like having a healthy diet and feeling good about yourself). In addition, we dove deep into the specific ingredient lists of our finalists and cross-checked them against WebMD and the National Institutes of Health (NIH) database to make sure that they did not contain ingredients known to be harmful.
Testosterone is used as a medication for the treatment of males with too little or no natural testosterone production, certain forms of breast cancer,[10] and gender dysphoria in transgender men. This is known as hormone replacement therapy (HRT) or testosterone replacement therapy (TRT), which maintains serum testosterone levels in the normal range. Decline of testosterone production with age has led to interest in androgen replacement therapy.[105] It is unclear if the use of testosterone for low levels due to aging is beneficial or harmful.[106]
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.

In contrast to steroids, testosterone boosters have a fully different mechanism of action. They are the products which contain the natural ingredients only. These ingredients act by stimulating the man’s body to synthesize own testosterone. So, testosterone levels grow naturally without negative health effects associated with the intake of steroids.


A: Endocrinology is a very difficult subject, some physicians and pharmacists alike have more difficulty with endocrinology than neurology. The reason for this is that there is no clear cut answer. Every hormone interacts with another hormone system in the body whether it be parathyroid hormone, cortisol, follicle stimulating hormone, etc. By in large, testosterone will increases lean body mass, which is to say that it typically increases muscle and or bone mass. We use it in the hospital to put weight on in patients needing to gain weight. That is partially the reason why we refer to testosterone as an "anabolic" hormone; anabolic meaning 'to build'.

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.
Bananas can be considered as energy-boosting snacks. You can eat it anytime of the day whenever you feel hungry or even while feeling bored. You would be unknowingly supplementing your body with some vitamins and minerals. A medium sized banana provides 32 milligrams of magnesium, along with potassium, vitamin C, fiber, and others. What more do you want from a light fruit!
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.
It's not enough just to increase the testosterone your body produces, because as we age, the testosterone we naturally produce is often bound by SHBG (sex hormone binding globulin) thus becoming unavailable for use in the body. It’s imperative that your testosterone remains unbound or “free” if you want to enjoy all the wonderful benefits testosterone provides.
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.
Male hypogonadism is a clinical syndrome caused by a lack of androgens or their action. Causes of hypogonadism may reflect abnormalities of the hypothalamus, pituitary, testes or target tissues. Increases in the amount of testosterone converted to estrogen under the action of the enzyme aromatase may also contribute to hypogonadism. Most aspects of the clinical syndrome are unrelated to the location of the cause. A greater factor in the production of a clinical syndrome is the age of onset. The development of hypogonadism with aging is known as late-onset hypogonadism and is characterised by loss of vitality, fatigue, loss of libido, erectile dysfunction, somnolence, depression and poor concentration. Hypogonadal ageing men also gain fat mass and lose bone mass, muscle mass and strength.

High intensity exercise is crucial to boost testosterone (13).  Exercises should be explosive in nature and maximize the resistant overload on the muscles.  Large muscle group compound lifts such as squats, deadlifts & burpees are some of the best testosterone boosting exercises.  The training session should be short (5-30 mins) and have very little rest periods between sets.

Men's levels of testosterone, a hormone known to affect men's mating behaviour, changes depending on whether they are exposed to an ovulating or nonovulating woman's body odour. Men who are exposed to scents of ovulating women maintained a stable testosterone level that was higher than the testosterone level of men exposed to nonovulation cues. Testosterone levels and sexual arousal in men are heavily aware of hormone cycles in females.[46] This may be linked to the ovulatory shift hypothesis,[47] where males are adapted to respond to the ovulation cycles of females by sensing when they are most fertile and whereby females look for preferred male mates when they are the most fertile; both actions may be driven by hormones.

In over two decades of medical practice, I've come to realize that the majority my patients' complaints stem from issues that are within their control—meaning diet and lifestyle changes can help them greatly. And that goes for hormonal imbalances, like low testosterone and high estrogen, as well. In previous articles I've outlined what men can do to address this common issue, including eating lots of healthy fats, HIIT exercises, and controlling stress. Once the easy stuff has been taken care of, it's time to tackle testing, bioidentical hormones, and supplements that can also help with low T.
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.
A diagnosis of low testosterone is typically made if a man’s free testosterone hormone level is below 300 ng/dL. But as a doctor specializing in sexual health, I typically consider optimized male testosterone levels somewhere between 600 to 800 ng/dL—rarely above or below those numbers. The tests that I routinely recommend to my male clients can be found in this test panel and include biomarkers associated with testosterone, free and total (this includes sex-hormone binding globulin [SHBG]), estradiol, estrogen (total and serum), cortisol, DHEAs, thyroid-stimulating hormone (TSH), hemoglobin A1C, and vitamin D.
You’re probably most familiar with testosterone as being the sex hormone responsible for defining “manhood.” And, yes, it does. However, proper levels of this key hormone are also necessary to stimulate sexual desire, increase libido, heighten arousal and ensure sexual satisfaction for both men and women. It’s also necessary to maintaining the following:

Your first step should be to see your doctor. If you think you have low testosterone, we cannot stress enough that you should proceed with caution and talk to a medical professional — taking a booster can definitely do more harm than good. Low testosterone can be a symptom of more serious problems, like a pituitary disorder or a side-effect of medication, and a booster can mask the root cause. A doctor will be able to evaluate your testosterone levels with a simple blood test, and if you both decide a booster is the way to go, give the ingredients of any supplement a once-over to make sure that they’re not at risk of making your personal health situation worse.

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.[151] 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][151][157][158] 5α-Reductase is highly expressed in the male reproductive organs (including the prostate gland, seminal vesicles, and epididymides),[159] skin, hair follicles, and brain[160] and aromatase is highly expressed in adipose tissue, bone, and the brain.[161][162] As much as 90% of testosterone is converted into 5α-DHT in so-called androgenic tissues with high 5α-reductase expression,[152] and due to the several-fold greater potency of 5α-DHT as an AR agonist relative to testosterone,[163] it has been estimated that the effects of testosterone are potentiated 2- to 3-fold in such tissues.[164]
When your testosterone levels go up, so does your libido. Unfortunately, the inverse is not true — your libido levels can go up without your testosterone levels also going up. And that’s how most supposed T-boosters “work”: they make you feel ornery, leading you to think that your T levels are appreciably higher, when they actually aren’t. In rare cases, supplementation will result in a 20% testosterone increase. This kind of improvement may sound impressive, but is irrelevant for practical purposes.
Testosterone is considered to be the "male hormone" that's produced in men by the testes. Although women's ovaries produce some testosterone, the hormone is produced in much higher concentrations in men and it is responsible for many of the secondary sex characteristics seen in men such as a deeper voice and hair on the chest, in addition to contributing to a healthy libido, building muscle mass, and maintaining energy levels.
The mineral zinc is important for testosterone production, and supplementing your diet for as little as six weeks has been shown to cause a marked improvement in testosterone among men with low levels.1 Likewise, research has shown that restricting dietary sources of zinc leads to a significant decrease in testosterone, while zinc supplementation increases it2 -- and even protects men from exercised-induced reductions in testosterone levels.3

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.


Overall there is evidence that testosterone treatment increases lean body mass and reduces obesity, particularly visceral obesity, in a variety of populations including aging men. With regard to muscle changes, some studies demonstrate improvements in maximal strength but the results are inconsistent and it has not been demonstrated that these changes lead to clinically important improvements in mobility, endurance or quality of life. Studies are needed to clarify this. Changes in abdominal obesity are particularly important as visceral fat is now recognised as predisposing the metabolic syndrome, diabetes and cardiovascular disease.


We kept it simple, and followed the premise of testosterone boosters: testosterone affects muscle gain, weight loss, and libido, so by increasing the amount of testosterone in the body, we can improve on each of those goals. This meant that we looked for ingredients proven to increase testosterone levels, not ingredients that might increase libido or help build muscle mass independently of testosterone (like having a healthy diet and feeling good about yourself). In addition, we dove deep into the specific ingredient lists of our finalists and cross-checked them against WebMD and the National Institutes of Health (NIH) database to make sure that they did not contain ingredients known to be harmful.


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.
Intramuscular testosterone injections were first used around fifty years ago. Commercially available preparations contain testosterone esters in an oily vehicle. Esterification is designed to retard the release of testosterone from the depot site into the blood because the half life of unmodified testosterone would be very short. For many years intramuscular preparations were the most commonly used testosterone therapy and this is still the case in some centers. Pain can occur at injection sites, but the injections are generally well tolerated and free of major side effects. Until recently, the available intramuscular injections were designed for use at a frequency of between weekly and once every four weeks. These preparations are the cheapest mode of testosterone treatment available, but often cause supraphysiological testosterone levels in the days immediately following injection and/or low trough levels prior to the next injection during which time the symptoms of hypogonadism may return (Nieschlag et al 1976). More recently, a commercial preparation of testosterone undecanoate for intramuscular injection has become available. This has a much longer half life and produces testosterone levels in the physiological range throughout each treatment cycle (Schubert et al 2004). The usual dose frequency is once every three months. This is much more convenient for patients but does not allow prompt cessation of treatment if a contraindication to testosterone develops. The most common example of this would be prostate cancer and it has therefore been suggested that shorter acting testosterone preparations should preferably used for treating older patients (Nieschlag et al 2005). Similar considerations apply to the use of subcutaneous implants which take the form of cylindrical pellets injected under the skin of the abdominal wall and steadily release testosterone to provide physiological testosterone levels for up to six months. Problems also include pellet extrusion and infection (Handelsman et al 1997).
12)  Use Aswaghanda and Collagen Protein:  This adaptogenic herb has been shown to reduce stress hormone, increase DHEA and boost testosterone levels.  You can take the Cortisol Defense to help you get restorative sleep at night which will support your testosterone.  In addition, I personally enjoy using the Organic Bone Broth Collagen in addition to the Amino Strong for a post weight training shake.  This protein powder has all the benefits of collagen protein and it has 500 mg of high potency ashwagandha in each serving!
Epidemiological evidence supports a link between testosterone and glucose metabolism. Studies in non-diabetic men have found an inverse correlation of total or free testosterone with glucose and insulin levels (Simon et al 1992; Haffner et al 1994) and studies show lower testosterone levels in patients with the metabolic syndrome (Laaksonen et al 2003; Muller et al 2005; Kupelian et al 2006) or diabetes (Barrett-Connor 1992; Andersson et al 1994; Rhoden et al 2005). A study of patients with type 2 diabetes using measurement of serum free testosterone by the gold standard method of equilibrium dialysis, found a 33% prevalence of biochemical hypogonadism (Dhindsa et al 2004). The Barnsley study demonstrated a high prevalence of clinical and biochemical hypogonadism with 19% having total testosterone levels below 8 nmol/l and a further 25% between 8–12 nmol/l (Kapoor, Aldred et al 2007). There are also a number longitudinal studies linking low serum testosterone levels to the future development of the metabolic syndrome (Laaksonen et al 2004) or type 2 diabetes (Haffner et al 1996; Tibblin et al 1996; Stellato et al 2000; Oh et al 2002; Laaksonen et al 2004), indicating a possible role of hypogonadism in the pathogenesis of type 2 diabetes in men. Alternatively, it has been postulated that obesity may be the common link between low testosterone levels and insulin resistance, diabetes and cardiovascular disease (Phillips et al 2003; Kapoor et al 2005). With regard to this hypothesis, study findings vary as to whether the association of testosterone with diabetes occurs independently of obesity (Haffner et al 1996; Laaksonen et al 2003; Rhoden et al 2005).
There is also a crazy case study about a Thai-male who reportedly got his DHT levels all the way to 158% above medical reference ranges after supplementing with Butea Superba (he visited the doctor and complained of too high libido), after some examination and questioning, the doctors thought it might be the supplement causing this sudden increase in androgenic hormones and they instructed him to seize the consumption. Within a week his blood serum 5-a DHT had fallen back to normal.
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.

Now that we know chronic insulin spikes lead to lower Testosterone production, I hope I haven’t sent you running into the low carb camp! There are a few studies out there showing that long term low carb or ketogenic dieting leads to higher cortisol levels (especially with subjects who are training), and decreased testosterone levels (28 & 29). I have used low carb diets in the past with successful results (winning a national bodybuilding title), however the key is to use cyclical carb re-feeds. If you’re going to go on a low carb diet for whatever reason, be sure to work in a large carb reefed once a week.
I am also suspect of the fact that men 100 years ago had testosterone levels of 800-2000 ng/dL. The truth is that there are men today that are stronger and more muscular than the men from 100 years ago. Sure the “average man” of today is less than the “average man” of prior generations, but this is because we sit around in offices all day, and then come home to sit on the couch and watch tv…little to no activity.
It’s worth emphasizing that these supplements are totally legit. They’re NOT steroids. Meaning, only the natural and harmless ingredients have been used to make these products, which can help the guys dealing with the low testosterone problems, such as low energy, fatigue, muscle loss, irritability, and similar. Usually, the guys tend to start experience these problems in their late 20s and in some cases in their early 30s.
Testosterone levels generally peak during adolescence and early adulthood. As you get older, your testosterone level gradually declines — typically about 1 percent a year after age 30 or 40. It is important to determine in older men if a low testosterone level is simply due to the decline of normal aging or if it is due to a disease (hypogonadism).
