NEW YORK, March 5, 2013 /PRNewswire/ -- Everyone knows testosterone is what makes a man a man, yet for years, testosterone boosters were almost solely the province of competitive bodybuilders. But all that is changing with TestroVax™, a revolutionary new product that's generating a surprising amount of excitement among the general consumer market. So why are even non-bodybuilders suddenly becoming so interested in boosting their testosterone levels? Because testosterone is directly related to muscle strength, cognitive function, body composition, positive self-perception, energy, vigor, aggression, assertiveness and, last but not least, sexual performance… things ALL men are concerned about, not just bodybuilders. And the key compound in TestroVax not only increases testosterone levels by an amazing 42.1%, but it does this in just 12 days. That's right… just 12 days. This is critical for men, because unfortunately, testosterone levels decrease with age. And men over 40 are no longer willing to just accept the changes this can cause in their bodies. They're determined to keep their edge… they want more. Of course, so-called "natural" testosterone boosters and "pills for men" have lined the shelves of vitamin stores for decades, but many have been largely ignored (simply because the efficacy of some of these pills was, at best, questionable). But now-- finally --some groundbreaking new research has revealed that the powerful, proprietary, key compound in TestroVax is actually capable of boosting testosterone levels by 42.1% in just 12 days… no injections, no greasy gels. Need the proof? In a double-blind, placebo-controlled clinical trial, 43 men were divided into two groups: 1) the functional TestroVax compound group and 2) a placebo group. All subjects consumed their test product every morning at breakfast for 12 consecutive days, and blood samples were taken before use, after 6 and 12 days of use, and 3 days after stopping use. All blood samples were drawn between 9:30-10:30 a.m., a time of day when serum oscil lations of testosterone are at their minimum. Results showed that serum testosterone levels in the experimental group were significantly increased compared to those of the placebo group over the course of the study, wherein the key TestroVax compound led to a 42.1% increase in testosterone after 12 days of use. Interestingly, 3 days after the suspension of use, testosterone was still significantly increased compared to baseline in the experimental group, showing a lasting effect.
