Tribulus Terrestris is a powerful plant extract which has been shown to increase the body’s natural production of testosterone, (an anabolic male hormone, key to lean muscle buildup).
European studies suggest that it can increase testosterone levels by as much as 50%! The increased testosterone levels translates into the acceleration of muscle growth, stimulation of the entire metabolism which results in reduction of body fat, the increase of muscular strength and the increase of the libido.
