NutraBio Tribulus Terrestris

Tribulus terrestris has been shown in studies to enhance lutenizing hormone (LH)(or pre-testosterone) production by as much 186% and raise testosterone levels as much as 40%. Saponin is 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.
