Natural Testosterone Liberator and Estrogen Blocker
Promotes Optimal Endogenous Anabolic Hormone Levels for Bodybuilders and Athletes
The
male hormone testosterone moves about the body in a free state (about
2% in normal men) or bound to one of two plasma proteins: sex
hormone-binding globulin (SHBG) or albumin. Only when testosterone is in
its free state can it interact with cellular receptors (e.g., trigger
muscle-building activity). Testosterone has two metabolites that pose
potential problems for aging males and also for bodybuilders and
athletes. One is estradiol (testosterone is converted to estradiol by
the enzyme aromatase) and the other is dihydrotestosterone (DHT)
(testosterone is converted to DHT by the enzyme 5-alpha reductase). As
men age, there is a dramatic decrease in testosterone production, but
without a corresponding decrease in the production of estradiol and DHT.
Even though testosterone levels have plummeted, the aromatization of
testosterone to estradiol is maintained, or even accelerated, and more
testosterone is also being aromatized in fatty tissues. This creates
excess levels of estradiol and, as a consequence, a blood level ratio of
testosterone to estradiol that continues to decline, tipping the scale
in balance of an estradiol-dominant environment.
