Rumor has it that the Kim sisters' testosterone pill received a reaction that no other product has ever gotten on Shark Tank. Apparently, after watching a presentation from the pair and hearing about how well their product has performed so far, all five judges got into a heated argument over who would make a deal with the two young entrepreneurs. It's been said that the fight lasted nearly an hour before the judges decided to do something that's never been done before. All five Sharks teamed up to invest an unbelievable $2.5 million into the Kim sisters' product!
As “the ultimate guide” I want this article to be the last resource you need when it comes to boosting your testosterone. I have spent years researching this stuff, and experimenting on myself. And in case I am incomplete, I have linked out at the bottom of this page to all the best resources for increasing testosterone around the web. I truly believe there is no better resource out there than what you’re reading right now.

Dr. Anthony's Notes: Creatine is damn effective. Period. It's research proven to benefit testosterone, energy levels, muscle preservation, and your brain function. Although creatine can be found naturally in a good high-protein diet, taking 5g daily is a great idea for most guys – especially those over 35. Remember to take your creatine AWAY from caffeine – the two substances inhibit each other's absorption. Verdict: this is one of the natural testosterone supplements that work. Best Food Sources: wild game (including venison, elk, buffalo, and bison), grass-fed beef, organic chicken, organic turkey, and wild-caught fish. How To Take Creatine Monohydrate: 5g daily away from caffeine.
Imagine if there was a pill that would transform your dick into an unstoppable orgasm machine; A pill that gave you the confidence to talk to any girl, because you knew one night with you and she would be begging for your cock. Women are attracted to men that can make them climax. The most PATHETIC trait a man can have is being bad at sex. But the exact opposite is also true.
Most people associate testosterone with facial hair, gigantic muscles & illegal steroids.  Naturally produced testosterone plays a very important role in male/female metabolic function.  Lowered testosterone is a chronic epidemic that is threatening lives all around the world.  This article will go over 12 ways to boost testosterone levels naturally through healthy lifestyle measures.
Take 250 mg of Forskolin, standardized to 10 percent, twice a day. Take one serving before training and the other with a meal. According to "Natural Anabolics," Forskolin decreased body fat and increased free testosterone levels in training individuals as compared to a placebo. Forskolin comes from the herb coleus forskohlii and is also known as Forslean.

For men with low blood testosterone levels, the benefits of hormone replacement therapy usually outweigh potential risks. However, for most other men it's a shared decision with your doctor. It offers men who feel lousy a chance to feel better, but that quick fix could distract attention from unknown long-term hazards. "I can't tell you for certain that this raises your personal risk of heart problems and prostate cancer, or that it doesn't," Dr. Pallais says.
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.

If in a 46 XY individual testosterone is either not produced in adequate concentrations as in gonadal dysgenesis (MacLaughlin and Donahue 2004), or in the absence of the enzyme 17 alpha-hydroxylase so that testosterone is not produced (Ergun-Longmire et al 2006), or testosterone androgen receptors are absent as in the androgen insensitivity syndrome (Hughes and Deeb 2006), phenotypic females will result.
TestoTEK has all the core ingredients and they are in big-time potencies. D aspartic acid, vitamin D3 and zinc are probably the most important testosterone ingredients in existence. Much clinical research has shown these to be unquestionably the most important. TestoTEK has as much or more of these three ingredients than any other supplement we have reviewed.
That said, magnesium is one of a few ingredients demonstrated to impact testosterone levels. Researchers at Italy’s University of Palermo found that magnesium improved participants’ anabolic hormone status — including their testosterone levels. In a follow-up study, they confirm that even adjusting for age differences in their participant group, “magnesium was positively associated with total testosterone.” They propose that magnesium supplementation might help improve muscle performance in aging men — a group particularly vulnerable to declining/low testosterone levels. Outside of Italy, researchers at Turkey’s Selçuk University found that magnesium supplementation increased testosterone levels for both athletes and more sedentary men alike.
Butter is notorious for its saturated fat. However, it contains a small amount of vitamin D. With the help of its fat content it will also aid your body to absorb and use the vitamin D from other sources. Butter is a healthy as long as you consume it moderately. Don't swallow it as a whole as you think it'll boost up testosterone instantly. You will end up being the opposite way you want.
It seems like today it’s a badge of honor to train every day until exhaustion. The ethos is to push yourself harder and harder every day. If that’s your philosophy towards exercise, you might be sabotaging your testosterone levels (as well as your 20 Mile March). Studies have shown that overtraining can reduce testosterone levels significantly. Yes, it’s important to exercise hard, but it’s even more important to give your body rest so it can recuperate from the damage you inflicted upon it.
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”.
Both testosterone and 5α-DHT are metabolized mainly in the liver.[1][151] Approximately 50% of testosterone is metabolized via conjugation into testosterone glucuronide and to a lesser extent testosterone sulfate by glucuronosyltransferases and sulfotransferases, respectively.[1] An additional 40% of testosterone is metabolized in equal proportions into the 17-ketosteroids androsterone and etiocholanolone via the combined actions of 5α- and 5β-reductases, 3α-hydroxysteroid dehydrogenase, and 17β-HSD, in that order.[1][151][152] Androsterone and etiocholanolone are then glucuronidated and to a lesser extent sulfated similarly to testosterone.[1][151] The conjugates of testosterone and its hepatic metabolites are released from the liver into circulation and excreted in the urine and bile.[1][151][152] Only a small fraction (2%) of testosterone is excreted unchanged in the urine.[151]
show that total testosterone levels increase after exercising, especially after resistance training. Low testosterone levels can affect your sex drive and your mood. The good news is that exercise improves mood and stimulates brain chemicals to help you feel happier and more confident. Exercise also boosts energy and endurance, and helps you to sleep better. Fitness experts recommend 30 minutes of exercise every day.
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.
In fact, high cortisol deals a crushing blow to testosterone in two ways. During, long-lasting stress, high amounts of cortisol release very often and have a direct negative influence on T levels. Thus, cortisol inhibits testosterone synthesis in the testes and hypothalamus. In addition, the production of cortisol is impossible without cholesterol. But testosterone synthesis also demands cholesterol. Since during stress cholesterol is first of all used for making cortisol, T levels simply plummet.

The maximum hormone concentration in the blood is reported immediately after the workout. And the effect lasts throughout the day. However, it’s important to ensure that your physical activity is moderate. The matter is that too much high-intensity exercise can give an undesirable result. But even if for any reason you can’t attend a gym, it’s not a problem. Just move as much as possible during the day. Even simple walking will be of great benefit.


In many of the studies we found, those who saw the most improvement in health, testosterone, or muscle gain were those with existing nutrient or vitamin deficiencies. This means that some gains may be due more to dietary changes and generally restoring nutrient and vitamin levels than any one magic ingredient, but also that making sure your diet includes healthy amounts of nutrients should be your first step.
You can find a whole bunch of HIIT workouts online, but the one I used during my 90-day experiment was a simple wind sprint routine. On Tuesdays I went to the football field near my house, marked off 40 yards with some cones, and sprinted as fast as I could. I’d slowly walk back to the starting line, giving my body about a minute to rest, and then I’d sprint again. I typically did 40 sets of 40-yard sprints in a workout. I love sprints.
It is hard to know how many men among us have TD, although data suggest that overall about 2.1% (about 2 men in every 100) may have TD. As few as 1% of younger men may have TD, while as many as 50% of men over 80 years old may have TD. People who study the condition often use different cut-off points for the numbers, so you may hear different numbers being stated.

Directions — SUGGESTED USE: As a dietary supplement take 3 capsules daily, preferably with a meal, or as directed by a healthcare professional. — Take two capsules with a meal twice a day. On days that you are not training, take two capsules in the morning and two capsules at night. On days that you train, take two capsules about an hour before workouts and take two capsules in the morning or at night depending on when you train.

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.
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).
A: If a health insurance company is providing coverage for a medication, including testosterone replacement therapy, they determine the final cost of the product. Costs will vary from one health insurance plan to another. To determine the costs of the testosterone replacement options, the health insurance plan should be contacted. There are various options for testosterone replacement therapy including gels, injections, patches, and tablets that dissolve under the lip. All of the formulations can be effective and each has advantages and disadvantages. The most appropriate testosterone replacement therapy depends on a variety of factors, including cost, patient preference, and tolerability. Testosterone replacement gels, such as AndroGel and Testim, are very effective and easy to administer. AndroGel and Testim can be easily applied to the skin once daily. However, the gels can be irritating to the skin and AndroGel and Testim are typically quite expensive. Testosterone replacement injections, such as Depo-Testosterone (testosterone cypionate) and Delatestryl (testosterone enanthate), are usually inexpensive. The injections are given only once every one to two weeks. The major disadvantage with injectable testosterone is that testosterone levels may be difficult to control. Levels may be too high after an injection and too low before the following injection. A testosterone replacement patch, such as Androderm, is applied every night and left on for 24 hours. Androderm can be applied to the arm, back or stomach, in an area without too much hair. Androderm can cause irritation of the skin. A testosterone tablet, Striant, is placed under the upper lip against the gums and replaced every 12 hours. Striant molds to the upper gum so that eating and drinking can occur normally. The testosterone tablet can irritate the gums and cause a bitter taste and toothache. People with low testosterone should work with their doctor or healthcare provider to find a safe, effective, and affordable testosterone replacement option for them. For more specific information, consult with your doctor or pharmacist for guidance based on your health status and current medications, particularly before taking any action. Derek Dore, PharmD
If your priority is to find and use a safe, effective, and natural testosterone booster, then you have every right to ask yourself do all of these hormone supplements work for real? Also, do they work at all? Are you going to waste your money or finally find an answer to your burning questions? Well, long story short, the testosterone supplements do their work just fine.
It seems like today it’s a badge of honor to train every day until exhaustion. The ethos is to push yourself harder and harder every day. If that’s your philosophy towards exercise, you might be sabotaging your testosterone levels (as well as your 20 Mile March). Studies have shown that overtraining can reduce testosterone levels significantly. Yes, it’s important to exercise hard, but it’s even more important to give your body rest so it can recuperate from the damage you inflicted upon it.
Another effect that can limit treatment is polycythemia, which occurs due to various stimulatory effects of testosterone on erythropoiesis (Zitzmann and Nieschlag 2004). Polycythemia is known to produce increased rates of cerebral ischemia and there have been reports of stroke during testosterone induced polycythaemia (Krauss et al 1991). It is necessary to monitor hematocrit during testosterone treatment, and hematocrit greater than 50% should prompt either a reduction of dose if testosterone levels are high or high-normal, or cessation of treatment if levels are low-normal. On the other hand, late onset hypogonadism frequently results in anemia which will then normalize during physiological testosterone replacement.
The mechanism of age related decreases in serum testosterone levels has also been the subject of investigation. Metabolic clearance declines with age but this effect is less pronounced than a reduction in testosterone production, so the overall effect is to reduce serum testosterone levels. Gonadotrophin levels rise during aging (Feldman et al 2002) and testicular secretory responses to recombinant human chorionic gonadotrophin (hCG) are reduced (Mulligan et al 1999, 2001). This implies that the reduced production may be caused by primary testicular failure but in fact these changes are not adequate to fully explain the fall in testosterone levels. There are changes in the lutenising hormone (LH) production which consist of decreased LH pulse frequency and amplitude, (Veldhuis et al 1992; Pincus et al 1997) although pituitary production of LH in response to pharmacological stimulation with exogenous GnRH analogues is preserved (Mulligan et al 1999). It therefore seems likely that there are changes in endogenous production of GnRH which underlie the changes in LH secretion and have a role in the age related decline in testosterone. Thus the decreases in testosterone levels with aging seem to reflect changes at all levels of the hypothalamic-pituitary-testicular axis. With advancing age there is also a reduction in androgen receptor concentration in some target tissues and this may contribute to the clinical syndrome of LOH (Ono et al 1988; Gallon et al 1989).
Consume vegetable carbohydrates and healthy fats. Your body requires the carbohydrates from fresh vegetables rather than grains and sugars. In addition to mono- or polyunsaturated fats found in avocados and raw nuts, saturated fats are also essential to building your testosterone production. According to research, there was a decrease in testosterone stores in people who consumed a diet low in animal-based fat.11 Aside from avocados and raw nuts, ideal sources of healthy fat that can boost your testosterone levels include:

Since then there have been many publications documenting suppressed testosterone and gonadotropins (Daniell 2006) in men using opioid medications whether these agents were administrated orally (Daniell 2002) or intrathecally (Finch et al 2000). Not only do opioids act centrally by suppressing GnRH, they also act directly on the testes inhibiting the release of testosterone by Leydig cells during stimulation with human chorionic gonadotropin (Purohit et al 1978). Although the large majority of men (and women) receiving opioids do develop hypogonadism, about 15 percent also develop central hypocorticism and 15 percent develop growth hormone deficiency (Abs et al 2000).
It's important to understand that your body requires saturated fats from animal and vegetable sources (such as meat, dairy, certain oils, and tropical plants like coconut) for optimal functioning, and if you neglect this important food group in favor of sugar, grains and other starchy carbs, your health and weight are almost guaranteed to suffer. Examples of healthy fats you can eat more of to give your testosterone levels a boost include:
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.
I bought most of the ingredients for my Testosterone Salad at Whole Foods. For those curious, I added up all the ingredients and divided by six (I typically ate six of these salads in a week). The cost per salad was roughly $5. That’s about the price many folks pay every day for a crappy fast food meal. If you’re on a budget, I’m sure you could get the ingredients at Walmart and bring the cost per salad down even more.
Researchers at Ball State University found that “strength training can induce growth hormone and testosterone release.” (6) Another study from the University of Nebraska Medical Center researched the acute effects of weight lifting on serum testosterone levels. (7) The results concluded that even moderate weight lifting and light weightlifting increased serum testosterone levels in participants.
On the average, you need to sleep at least 8 hours per night to stay healthy. If you want a night sleep to contribute to the maximum testosterone production, it’s important to make your sleep comfortable. Thus, the bedroom temperature shouldn’t exceed 21°C. In addition, you should ventilate your bedroom thoroughly before sleeping. Furthermore, before going to bed, don’t overload your stomach with fatty foods, as well as don’t drink alcohol and caffeinated beverages. Finally, you have to avoid intense physical activity before bedtime.6
Consume enough zinc. Zinc is a mineral needed for many body functions including healthy immune function, bone strength and the production of testosterone. In fact, low levels of zinc are correlated to low levels of testosterone in men and teenage boys.[8] Mild zinc deficiency is now fairly common among Americans, so there's a good chance your teenage boy (particularly if he isn't a healthy eater) may be deficient. Ask your doctor for a blood test to get a better idea, but in the meantime, focus on serving and eating foods that are rich in zinc, such as meats, fish, low-fat milk, hard cheeses, beans and some nuts and seeds.
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”.

During the month before my experiment, I was definitely sleep deprived. Some nights I was only getting 4 to 5 hours. Testosterone killer! During my experiment I tried to get 8 to 9 hours of sleep at night as consistently as possible. I had to go to bed earlier, but I was only cutting into time that I would have been using to mindlessly surf the net anyway.

In this study, an ethical approval No. 20171008 was obtained from Ethical Committee of Qassim province, Ministry of Health, Saudi Arabia. At the beginning, a written informed consent was taken from a 30-year-old man for participation in this study. The patient came to the King Saud Hospital, Unaizah, Qassim, Saudi Arabia, with abdominal pain. He looked pale and hazy, hence, immediately admitted. A battery of lab tests was ordered by the attending physician. Moreover, abdominal ultrasound imaging was performed. The results of the tests showed high levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST), indicating liver injury. Other serum parameters, such as total proteins, albumin, and iron, in addition to the levels of kidney and heart enzymes were all found to be in the normal range. A complete blood count showed normal levels of red blood cells, white blood cells, and platelets. The ultrasound images of the man’s abdomen were all found to be normal as well [Figure 2]. The patient, a sportsman, described that he was taking a testosterone commercial booster product called the Universal Nutrition Animal Stak for the purpose of enhancing his testosterone profile to achieve a better performance and body composition. The attending physician decided to admit the man for 1 week. Some medications were prescribed, and the patient was discharged later after having fully recovered.
The diagnosis of late-onset hypogonadism requires the combination of low serum testosterone levels with symptoms of hypogonadism. Questionnaires are available which check for the symptoms of hypogonadism. These have been validated for the assessment of aging patients with hypogonadism (Morley et al 2000; Moore et al 2004) but have a low specificity. In view of the overlap in symptoms between hypogonadism, aging and other medical conditions it is wise to use a formal method of symptom assessment which can be used to monitor the effects of testosterone replacement.
This herb, used for centuries in foods, even poultices, was reported in the International Journal of Sport Nutrition and Exercise Metabolism to have reduced body fat and improved total testosterone levels versus a placebo in a double-blind trial. Fenugreek may also be helpful if you feel your sex drive is on the wane, as other research has found it can boost libido. You can get it in curries (it’s used to flavor them) and teas, or as a supplement in TestroVax, by Novex Biotech, which promises to boost testosterone levels 42% in 12 days. (novexbiotech.com)

This is because your body is really good at self-regulating your hormone levels. So if you have normal testosterone levels, boosting above your natural base level may at best give you a few hours while your body makes, and then immediately processes out, the excess testosterone. This means you might experience higher than your average testosterone levels, but not by much, and only for a little while.

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.
When you’re under stress (be it from lack of sleep, workplace stress, emotional stress, stress from a bad diet, overtraining etc.), your body releases cortisol. Cortisol blunts the effects of testosterone (47), which makes sense from an evolutionary point of view – if we were stressed as cavemen chances are it was a life or death situation – not running late to a meeting - in this state (i.e. running from a lion) the body wouldn’t care if you couldn’t get it up, there was more to worry about!

According to the Mayo Clinic, testosterone therapy can help treat hypogonadism. This condition occurs when the body can’t produce enough testosterone on its own. However, it’s unclear whether supplements can help. A study published in Nature Reviews Endocrinology found no scientific reason to prescribe testosterone to men over 65 years of age with normal or low to normal testosterone levels.

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.


Tailor the above recommendations to your personal needs and lifestyle. If you’re a vegetarian drop the bacon and steak, but keep the whey protein and eggs. If you have an injury that prevents you from heavy weightlifting, move as much as you can in the way that you can. There are no studies out there which can tell you exactly what will happen if you do X and Y, but not Z. And I certainly can’t tell you either. Don’t be afraid of self-education – that’s how I learned all this – and embrace the idea of conducting your own experiment and being your own test subject. Incorporate as many of the recommendations above as you’re comfortable with, consult your doctor, and track your results.
The mechanism of age related decreases in serum testosterone levels has also been the subject of investigation. Metabolic clearance declines with age but this effect is less pronounced than a reduction in testosterone production, so the overall effect is to reduce serum testosterone levels. Gonadotrophin levels rise during aging (Feldman et al 2002) and testicular secretory responses to recombinant human chorionic gonadotrophin (hCG) are reduced (Mulligan et al 1999, 2001).

Unlike aerobics or prolonged moderate exercise, short, intense exercise was found to be beneficial in increasing testosterone levels. The results are enhanced with the help of intermittent fasting. Intermittent fasting helps boost testosterone by improving the expression of satiety hormones, like insulin, leptin, adiponectin, glucacgon-like peptide-1 (GLP-1), cholecystokinin (CKK), and melanocortins, which are linked to healthy testosterone function, increased libido, and the prevention of age-induced testosterone decline. When it comes to an exercise plan that will complement testosterone function and production (along with overall health), I recommend including not just aerobics in your routine, but also:
