So out of all the natural testosterone boosting supplements out there I only really recommend tongkat ali extract, d-aspartic acid, and ashwagandha. There are a many others out there, but none that meet the standard that these do. And most of the other ones are actually in Testofuel. But remember, use at your own discretion. Even natural supplements can have side effects, so talk to your doctor first, and start slow.

Testosterone is a steroid sex hormone found in both men and women. In men, testosterone is produced primarily by the Leydig (interstitial) cells of the testes when stimulated by luteinizing hormone (LH). It functions to stimulate spermatogenesis, promote physical and functional maturation of spermatozoa, maintain accessory organs of the male reproductive tract, support development of secondary sexual characteristics, stimulate growth and metabolism throughout the body and influence brain development by stimulating sexual behaviors and sexual drive. In women, testosterone is produced by the ovaries (25%), adrenals (25%) and via peripheral conversion from androstenedione (50%). Testerone in women functions to maintain libido and general wellbeing. Testosterone exerts a negative feedback mechanism on pituitary release of LH and follicle-stimulating hormone (FSH). Testosterone may be further converted to dihydrotestosterone or estradiol depending on the tissue.

There is also solid research indicating that if you take astaxanthin in combination with saw palmetto, you may experience significant synergistic benefits. A 2009 study published in the Journal of the International Society of Sports Nutrition found that an optimal dose of saw palmetto and astaxanthin decreased both DHT and estrogen while simultaneously increasing testosterone.6 Also, in order to block the synthesis of excess estrogen (estradiol) from testosterone there are excellent foods and plant extracts that may help to block the enzyme known as aromatase which is responsible producing estrogen. Some of these include white button mushrooms, grape seed extract and nettles.7


Write down a list of the people you need to forgive and then do so. You can do that just yourself, between you and God, or you can do that in person — but it really is important. You can also turn to the Bible and other personal growth books, or seek out the help of a counselor or a good church. Really take care of those emotional issues, specifically resentment, unforgiveness, anger and frustration, and you’ll see that’s going to really help you cleanse you and detoxify spiritually. It’s going to also help naturally raise your testosterone levels.

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.
A: Testosterone is the male androgen, or sex hormone. It controls too many things to list here. While it does help regulate mood, sex drive, and metabolism, it does this by working in tandem with other hormones in your body. It's produced by the male testes and the adrenal glands.

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.
Ensure that you get adequate restful sleep each night. Sleeping less than the recommended 6 to 8 hours per night increases stress hormones, which lowers testosterone production. Additionally, learn to manage stress levels in healthy ways to naturally increase testosterone. Hormone replacement therapy may be required for some men with low testosterone levels. Consult your physician about treatment options.
This product is to be taken once daily on an empty stomach. Is there a particular time frame when food can be eaten? If I were to take this in the morning right when I wake up and then eat breakfast an hour later, is that fine? Also, mostly the only time of day my stomach is usually empty is right before going to bed. If it is taken at this time, will this affect sleep at all?
Vitamin D supplementation may potentially boost testosterone levels, but further research is needed to determine if it really has an effect on the testosterone levels of young people and athletes. The truth is likely similar to zinc and magnesium — being in a deficient state causes your testosterone levels to drop below baseline, and supplementing it just takes you right back to baseline (but not any higher).

Pellets. Your doctor will place the testosterone pellets under the skin of your upper hip or buttocks. Your doctor will give a shot of local anesthesia to numb your skin, then make a small cut and place the pellets inside the fatty tissues underneath your skin. This medication dissolves slowly and is released over about 3-6 months, depending on the number of pellets.

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.

I think that revamping your diet and lifestyle could be enough alone (no sugar, high fat, low carbs, lots of veggies, working out, low stress). Tongkat Ali would be an amazing added extra. I don’t know about mixing Tongkat with DAA and other stuff. Probably would be fine, but it’s strong. I usually say pick one. I know Testofuel has Fenugreek in it, but I don’t have too much experience with it. It has been proven to have effects. See this article.
“The Andro 400 has been a plus to my daily requirements of energy, stamina and weight loss. I have seen a noticeable reduction in my waistline from a 40" waist to a 37" waist. I am 6'6" and weighed 252, I now weigh 238 and feel much better. Without too much information, my sex drive and performance has been positively enhanced with greater sensitivity and stamina during those intimate times with my wife. Greater sensation, pleasure and results are evident.”

Decreased testosterone production in men with rheumatoid arthritis is a common finding (Stafford et al 2000), and it is now generally recognized that androgens have the capacity to suppress both the hormonal and cellular immune response and so act as one of the body’s natural anti-inflammatory agents (Cutolo et al 2002). This known anti-inflammatory action of testosterone has led to studying the effect of testosterone therapy in men with rheumatoid disease. Although not all studies have reported positive effects of testosterone treatment (Hall et al 1996), some studies do demonstrate an improvement in both clinical and chemical markers of the immune response (Cutolo et al 1991; Cutolo 2000). This observation would go along with more recent evidence that testosterone or its metabolites protects immunity by preserving the number of regulatory T cells and the activation of CD8+ T cells (Page et al 2006).


TT may help you but it may have adverse (harmful) results. (See discussion of these side effects below.) The Federal Drug Administration (FDA) has said that testosterone drug labels should state that there is a risk for heart disease and stroke for some men using testosterone products. All men should be checked for heart disease and stroke before, and periodically while on, TT. The AUA however, on careful review of evidence-based peer review literature, has stated that there is no strong evidence that TT either increases or decreases the risk of cardiovascular events.
Testosterone is a vital hormone for men, but just like estrogen in women, it goes down as you age. This is a natural process that has many drawbacks. In men, testosterone is responsible for hair growth, bone density, proper weight distribution, sex drive, muscle mass, red cell production, and so much more. But did you know that you can actually increase your testosterone levels as opposed to letting them dwindle?

Dr. Anthony’s Notes: I use Maca often in cycles throughout the year. I typically buy the raw Maca powder, which has a VERY “dirt-like” earthy taste. Beware if you are a bit squeamish on tastes! How To Take Maca: 1500-3000mg of Maca powder is a typical dosage take daily alongside food. From personal experience, I've found that it’s best to buy the Maca powder as a standalone supplement and throw it into a blended protein shake to mask the taste.

No one will argue with the well-established fact that the dramatic lows of testosterone as seen in castration or other significant primary testicular disturbances such as those induced by chemotherapy, radiation therapy, congenital problems, or as seen in secondary testicular insufficiency (eg, large compressive pituitary or hypothalamic tumors) produce dramatic signs and symptoms of testosterone deficiency that require testosterone replacement therapy. Less clear, or at least more controversial, is the necessity of treating the gentler reduction of testosterone seen in the aging process.

Intracoronary artery infusion of testosterone causes significant coronary artery dilatation and not constriction as previously thought (Webb et al 1999). When degree of coronary obstruction is assessed by angiography, there is a direct relationship between degree of coronary artery narrowing and reduced testosterone levels (Phillips et al 1994). Men with low testosterone levels have been observed to have: premature atherosclerosis, increased visceral adipose tissue, hyperinsulinemia, and other risk factors for myocardial infarction (Phillips 2005). Insulin resistance has been shown to be associated with a decrease in Leydig cell secretion of testosterone (Pitteloud et al 2005). Muller and colleagues suggest that low endogenous total testosterone and SHBG levels increase the risk of metabolic syndrome in aging and aged men. They demonstrated that low levels of testosterone are related to lower insulin sensitivity and higher fasting insulin levels (Muller et al 2005). These authors speculate that testosterone might play a protective role in the development of metabolic syndrome, insulin resistance, diabetes mellitus and cardiovascular disease in aging men.


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.
