Reverses 42 years of testosterone loss in only 12 days!

An amino acid and neurotransmitter, D-AA triggers the release of luteinizing hormone (LH), which in turn stimulates the testes to pump out more testosterone. In one study, 23 men ages 27 to 37 took a daily dosage of slightly more than 3 grams of D-AA. After 12 days, their testosterone levels rose by an average of 42%. Given that the average male loses 1% of his testosterone annually, that’s equivalent to reversing 42 years of testosterone loss in less than 2 weeks!

In another study, men with impaired fertility were given 2.7 grams of D-AA daily for 90 days. The results showed improvements in motility and concentration of semen ranging from 50% to 100%, which was associated with increased sexual potency. The study also found a 30% to 60% increase in serum testosterone.

Increases availability of Prime Male's T boosters up to 20X!

U.S. clinical studies have shown that this patented "bioavailability enhancer" increases the absorption rates of nutrients in dietary supplements by as much as 20-fold. We include black pepper in Prime Male to speed up the restoration of your body’s testosterone to youthful levels.

Increased bioavailability for a bigger testosterone boost

Boron can affect hormones, inflammation, blood plasma, vitamin D, bone maintenance, and cognition. Prime Male uses boron amino acid chelate, which is more bioavailable than other forms.

In a study conducted by Naghii, men who took 10 mg of boron daily for a week decreased their sex hormone binding globulin (SHBG) significantly, resulting in a 28% increase in free testosterone. In addition, their estrogen levels dropped by 39%.

And in a study conducted by Miljkovic, men taking 6 mg boron daily for 2 months increased free testosterone levels on average by 29.5%.

A gift from the Orient: a new lease on male vitality

Asian red ginseng has been used for centuries to strengthen the immune system, boost energy, and increase longevity. In studies, ginseng has increased testosterone levels in lab animals and has also been used to treat male impotence.

One double-blind placebo study from Korea found that men who took ginseng for 8 weeks experienced significant improvements in erection quality, performance, and sexual satisfaction vs. a control group not consuming the herb.

In a double-blind study with 60 men suffering from mild to moderate erectile dysfunction, those who took Korean Red Ginseng for 12 weeks had significant improvement in erectile function compared to men taking a placebo.

Blocks the production of "girly" hormones

Chinese researchers screened 1,431 natural compounds and discovered that among them, the citrus flavonoid luteolin is the most powerful aromatase inhibitor. By inhibiting the action of aromatase, luteolin reduces the body’s production of estrogen. It also stimulates androgens to make more testosterone.

An article published in Current Cancer Drug Targets reports that luteolin binds to estrogen receptors, which may help reduce estrogen production.

A flare for making men more, well … "manly"

The magnesium atom contains so much energy that, when lit, a strip of magnesium flares with a blinding white light. Without magnesium, plants cannot perform photosynthesis, and all life on Earth would end.

Approximately 60% of your total testosterone is bound into sex hormone binding globulin (SHBG), which makes the male hormone unavailable for your body to use directly. Magnesium lowers your SHBG count, raising your levels of "free" testosterone, which is the only form of testosterone that can deliver male potency health benefits.

Researchers at Selcuk University gave athletes 10mg magnesium daily for 4 weeks. One group did not exercise, while the other did 90 minutes of tae kwon do a day. In both groups, testosterone levels increase substantially vs. a control group not receiving magnesium.

And doctors at the University Hospital of Parma found that older men with elevated magnesium levels also had higher concentrations of serum testosterone. The citrate form is absorbed significantly better in the body than other forms of magnesium.

An ancient herb with testosterone boosting properties

Ashwagandha is an exotic herb which grows in warm climates and has been used as medicine for hundreds of years. It has been linked to reduced anxiety and stress, lower blood sugar levels, and most importantly, studies show it could increase testosterone levels.

Ashwagandha literally translates as "smell of the horse" mainly down to its aroma, but also thanks to its centuries long reputation of improving potency and making men like you stronger. Enjoy increased strength in the gym, better muscle tone and improved stamina thanks to the legendary Ashwagandha.

Takes the "sting" out of male aging

More than half of your body’s testosterone is bound to a protein called sex hormone binding globulin (SHBG), rendering the testosterone essentially inert.

Lignans, compounds derived from the root of the stinging nettle, have the ability to bind with SHBG in place of the testosterone. The result is more testosterone freely available to your system. Plus, nettle root contains beta-sitosterol, which also helps elevate testosterone levels.

Nettles have also been shown to significantly decrease estrogen levels, another proven strategy for raising serum testosterone. Note: In Prime Male we use only the roots, which have much stronger effects than the leaves, seeds, and the rest of the nettle plant.

Makes the building blocks of testosterone molecules

Before it makes testosterone, your body produces androgen, a hormone that is a precursor for testosterone. Vitamin B6 stimulates androgen receptors that signal your testes to start pumping testosterone into your blood stream. It also alleviates mood problems and loss of libido. In an animal study published in the Journal of Steroid Biochemistry, lab rats kept on a diet free of vitamin B6 for a month suffered a 74.5% drop in testosterone levels.

Vitamin B6 also enhances your body’s absorption of two other important testosterone boosters in Prime Male: zinc and magnesium. P-5-P is the active form of B6, which means the full benefits of the vitamin are available immediately after absorption.

The sun gives you free vitamin D … but not enough

Sunlight triggers production of vitamin D3, which is vital to good health. In fact, vitamin D is one of only 24 nutrients critical for human survival. An article in the Journal of Endocrinology links low vitamin D levels with low testosterone and decreased life span. But most people don’t spend enough time outside to produce sufficient vitamin D3.

To correct that deficiency, Prime Male gives you a big daily of vitamin D3, far more than you would get catching rays or drinking a glass of milk. Multiple studies suggest that men with higher levels of vitamin D3 also have higher testosterone levels. A study from Stanford University found that vitamin D regulates levels of both estrogen and testosterone.

Another study, from the Medical University of Graz, found that a year of supplementing with vitamin D increased participants' testosterone levels by 20% on average.

Works synergistically with vitamin D3

Vitamin K2 enables natural testosterone booster vitamin D3 to work better in your body. Plus, vitamin K2 helps boost testosterone on its own.

Nutritionists at Tohoku University in Japan have concluded that vitamin K2 increases serum testosterone levels significantly by enhancing the activity of certain enzymes inside the testicles. In one animal study, lab rats fed vitamin K2 for 5 weeks experienced a 50% increase in testosterone levels compared with a control group not fed K2.

We use Menaquinone-7 in Prime Male, an enhanced bioactive form of vitamin K2 that is better absorbed and more effective than other forms.

A metal that can put more spring in your step and iron in your rod

Low zinc levels, which millions of American men suffer, prevent the pituitary gland from releasing luteinizing hormone, needed to stimulate testosterone production in the testes. Boosting zinc levels releases more LH, so your body can ramp up testosterone production.

In one study, zinc supplementation almost doubled serum testosterone levels in 9 elderly men who were marginally zinc deficient – and it happened in just 6 months. In the same study, another group of 4 men ages 27 to 28 had their dietary zinc restricted. Within 20 weeks, their testosterone levels dropped by almost 73%.

In another study, football players took zinc, magnesium, and vitamin B6 for 8 weeks. Result: free testosterone increased 33.5% in only 2 months.

Warning: your body cannot store or manufacture zinc, so it is essential to continually ingest it in food and through supplementation. Sexually active men deplete their zinc rapidly, losing 5 mg of zinc per ejaculation. The citrate form has significantly greater bioavailability than other forms of zinc.
