Pharmaceutical grade HPLC certified 100% pure! Micronized for maximum bio-availability. Tribulus Increases Testosterone Levels Naturally Increased testosterone levels will improve strength & stamina. Athletes use Tribulus to help ensure their own natural levels of testosterone are normal at all times. Maintaining testosterone levels keeps anabolic (muscle building) hormones at optimum levels which in turn blunts catabolic (Muscle deteriorating) hormones such as cortisol (Stress hormone). Tribulus is a Andro/pro-hormone alternative that can be used to naturally increase testosterone levels. When stressor hormones rise fatigue sets in and reduces performance by enhancing the perception of effort. The body will begin to breakdown muscle for energy if stressor hormones are not blunted. Benefit Of Using Tribulus Terrestris •Increases Natural Testosterone Levels •Higher Energy Levels, Endurance, & Stamina •Enhances Sexual Drive & Performance •May improve sperm production •May improve reproductive function, libido, & ovulation •Stimulates Lutenizing Hormone (LH) Production Tribulus Enhances Lutenizing Hormone (LH) Production Tribulus terrestris has been shown in studies to enhance lutenizing hormone (LH)production by as much 186% and raise testosterone levels as much as 40%. Saponinis the active ingredient in tribulus that is responsible the beneficial effects. Saponin works by stimulating the body's production of LH (or pre-testosterone), which in turn promotes the production of testosterone, the key male hormone responsible for helping to add lean body mass, increase metabolism and keep libido or sex drive levels high. Studies Show DHEA Increases Tribulus Effects Studies show that it works very well when stacked with DHEA. It increased testosterone levels in a different way than either DHEA or andro do. Instead of being a testosterone precursor, it leads to the production of the luteinizing hormone (LH). When LH levels are increased, the natural production of testosterone also increases. LH is a hormone that also deals with sex drive. Now one can understand why it has been used to increase fertility and help with impotence. Laboratory animal studies found that Tribulus terrestris increased sperm count as well as motility levels after taking it for 30 days.
