Dr. Anthony’s Notes: DHEA is a powerful supplement for testosterone, energy, and overall well-being in our older Fit Fathers. A small dose of 25-50mg/day is enough to exert noticeable benefits. This supplement is over-the-counter. Verdict: this is one of the testosterone supplements that work. How To Take DHEA: Take 25-50mg once per day with food. Special Medical Note: DHEA is a MILD CYP3A4 inhibitor (a liver enzyme that processes MANY very common medications). This is the same isoenzyme that Grapefruit inhibits – albeit DHEA inhibits to a much weaker degree. If you’ve ever heard “don’t eat grapefruit with your Lipitor (cholesterol medication)”… this is the reason why. When we inhibit the CYP3A4 enzyme, more of the medications you're taking circulates (it’s not metabolized as fast). Check with your doctor for medication interactions before using DHEA.
The unsexy truth is that increasing T naturally simply comes down to making some long-term changes in your diet and lifestyle. As you’ll see, what I did to increase T largely boils down to eating better, exercising smarter, and getting more sleep. That’s pretty much it. But as with most things in life, the devil is in the details, so I’ll share with you exactly what I did and provide research that explains why the things I did helped boost my testosterone.
Early infancy androgen effects are the least understood. In the first weeks of life for male infants, testosterone levels rise. The levels remain in a pubertal range for a few months, but usually reach the barely detectable levels of childhood by 4–7 months of age.[15][16] The function of this rise in humans is unknown. It has been theorized that brain masculinization is occurring since no significant changes have been identified in other parts of the body.[17] The male brain is masculinized by the aromatization of testosterone into estrogen, which crosses the blood–brain barrier and enters the male brain, whereas female fetuses have α-fetoprotein, which binds the estrogen so that female brains are not affected.[18]
Testosterone functions within the brain. There are several lines of evidence for this: there are androgen receptors within the brain; testosterone is converted to both dihydrotestosterone (DHT) and estradiol by the actions of 5-α-reductase and aromatase respectively in the brain; steroid hormones promote neuronal cell growth and survival (Azad et al 2003). Testosterone enhances cerebral perfusion in hypogonadal men and that perfusion takes place specifically in Brodman areas 8 and 24, regions of the brain that are concerned with: strategic planning, higher motor action, cognitive behaviors, emotional behavior, generalized emotional reaction, wakefulness and memory (Greenlee 2000; Azad et al 2003). Studies of cognition demonstrate that older men with higher levels of free testosterone index (a surrogate measure of bioavailable testosterone) have better scores in tests of: visual memory, verbal memory, visuospatial functions and visuomotor scanning. Hypogonadal men have lower scores in tests of memory, visuospatial function, with a faster decline in visual memory (Moffat et al 2002). In a very small, short term placebo-controlled study hypogonadal men with Alzheimer’s Disease (AD) treated with testosterone demonstrated a modest improvement in a cognition assessment score in AD (Tan and Pu 2003).
Ok. So this product is meant to be taken continuously and without side-effects. But my question is, will there be replenishment from this product in aiding the body's natural ability to produce testosterone? In other words, will there ever be a time when I can say well I don't have to take this any more as my body is producing testosterone again on it's own and my muscle mass has been enhanced?

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

Any day that you don’t get 20 minutes of direct sunlight on your skin, you want to supplement with 5,000 IUs of vitamin D3. If you get your blood levels tested and you’re extremely low — below 50 IUs — you typically want to do 5,000 IUs twice a day for three months until you get those numbers up. You can do everything in the world, but if your vitamin D levels aren’t right, your testosterone levels will stay low.
The first of the natural testosterone boosters is intermittent fasting. One of the biggest intermittent fasting benefits? It’s been shown to increase testosterone by nearly 200 percent or even up to 400 percent. (4) In addition, a study by the University of Virginia Medical School noted that growth hormone levels increased 2,000 percent over the baseline in men who ate no calories for 24 hours, and growth hormone levels are correlated with testosterone. (5)
A sedentary lifestyle is another scourge for modern civilization. And this is a serious danger for men. After all, if physical activity is minimal, the testosterone levels will decrease steadily. And in this situation, strength training exercises are a proven method for raising testosterone. Thus, sports exercises always helped raise the levels of male sex hormone. As a result, the testosterone levels elevate after every workout.
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.
Testosterone is an essential hormone for men, and a decline in the levels can occur due to many reasons, but these natural supplements are great. They are safe to use and don’t have any side effects, that’s why you can take these supplements without doctor consultations. But if you have any other health issues, then consult a doctor before taking them.
A number of research groups have tried to further define the relationship of testosterone and body composition by artificial alteration of testosterone levels in eugonadal populations. Induction of a hypogonadal state in healthy men (Mauras et al 1998) or men with prostate cancer (Smith et al 2001) using a gonadotrophin-releasing-hormone (GnRH) analogue was shown to produce increases in fat mass and decreased fat free mass. Another experimental approach in healthy men featured suppression of endogenous testosterone production with a GnRH analogue, followed by treatment with different doses of weekly intramuscular testosterone esters for 20 weeks. Initially the experiments involved men aged 18–35 years (Bhasin et al 2001) but subsequently the study was repeated with a similar protocol in men aged 60–75 years (Bhasin et al 2005). The different doses given were shown to produce a range of serum concentrations from subphysiological to supraphysiological (Bhasin et al 2001). A given testosterone dose produced higher serum concentrations of testosterone in the older age group (Bhasin et al 2005). Subphysiological dosing of testosterone produced a gain in fat mass and loss of fat free mass during the study. There were sequential decreases in fat mass and increases in fat free mass with each increase of testosterone dose. These changes in body composition were seen in physiological and supraphysiological treatment doses. The trend was similar in younger versus older men but the gain of fat mass at the lowest testosterone dose was less prominent in older patients (Bhasin et al 2001; Bhasin et al 2005). With regard to muscle function, the investigators showed dose dependent increases in leg strength and power with testosterone treatment in young and older men but there was no improvement in fatigability (Storer et al 2003; Bhasin et al 2005).
Both men and women with Alzheimer’s Disease were found to have an increased concentration of SHBG and decreased free androgen index when compared with controls (Paoletti et al 2004). In a prospective study of 574 men whose baseline age span was 32–87 years and who were followed for a mean of 19.1 years (range, 4–37), the risk of developing Alzheimers’ Disease decreased 26 percent for each 10 unit increase in free testosterone index. The authors concluded that testosterone may be important for the prevention and treatment of AD (Moffat et al 2004).
Regardless of the method of testosterone treatment chosen, patients will require regular monitoring during the first year of treatment in order to monitor clinical response to testosterone, testosterone levels and adverse effects, including prostate cancer (see Table 2). It is recommended that patients should be reviewed at least every three months during this time. Once treatment has been established, less frequent review is appropriate but the care of the patient should be the responsibility of an appropriately trained specialist with sufficient experience of managing patients treated with testosterone.

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.

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

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'.

Dr. Anthony's Notes: When evaluating the efficacy of a product, it’s tough to balance the currently available human research with thousands of years of anecdotal evidence of efficacy. Tongkat Ali is a perfect example. All of the current studies are on animal models (not humans) – this DOES NOT mean that Tongkat Ali doesn’t work with humans. It simply means more research is needed. Personally, the strong experience of thousands of men (myself included) using this herb can confirm it’s libido enhancing effects. Also, this herb is DAMN BITTER. It makes Maca powder seem like a walk in the park. Hide in a smoothie or you will be sorry haha! How To Take Tongkat Ali: 200-300mg (of a 100:1 extract) 1-2 times per day. If you are using the raw powder (recommended below) that is NOT encapsulated, definitely hide the powder in a fat burning smoothie like the “Fit Father Fat Burning Shake Recipe” we recommend in FF30X. Again, I cannot understand how damn nasty this powder tastes. Beware!

Vitamin D deficiency is a growing epidemic in the US, and is profoundly affecting men’s health. The cholesterol-derived steroid hormone vitamin D is crucial for men’s health. It plays a role in the development of the sperm cell nucleus, and helps maintain semen quality and sperm count. Vitamin D can also increase your testosterone level, helping improve your libido. Have your vitamin D levels tested using a 25(OH)D or a 25-hydroxyvitamin D test. The optimal level of vitamin D is around 50 to 70 ng/ml for adults. There are three effective sources of vitamin D:

Cross-sectional studies conducted at the time of diagnosis of BPH have failed to show consistent differences in testosterone levels between patients and controls. A prospective study also failed to demonstrate a correlation between testosterone and the development of BPH (Gann et al 1995). Clinical trials have shown that testosterone treatment of hypogonadal men does cause growth of the prostate, but only to the size seen in normal men, and also causes a small increase in prostate specific antigen (PSA) within the normal range (Rhoden and Morgentaler 2005). Despite growth of the prostate a number of studies have failed to detect any adverse effects on symptoms of urinary obstruction or physiological measurements such as flow rates and residual volumes (Snyder et al 1999; Kenny et al 2000, 2001). Despite the lack of evidence linking symptoms of BPH to testosterone treatment, it remains important to monitor for any new or deteriorating problems when commencing patients on testosterone treatment, as the small growth of prostate tissue may adversely affect a certain subset of individuals.
Present in much greater levels in men than women, testosterone initiates the development of the male internal and external reproductive organs during foetal development and is essential for the production of sperm in adult life. This hormone also signals the body to make new blood cells, ensures that muscles and bones stay strong during and after puberty and enhances libido both in men and women. Testosterone is linked to many of the changes seen in boys during puberty (including an increase in height, body and pubic hair growth, enlargement of the penis, testes and prostate gland, and changes in sexual and aggressive behaviour). It also regulates the secretion of luteinising hormone and follicle stimulating hormone. To effect these changes, testosterone is often converted into another androgen called dihydrotestosterone.
