Tribulus Terrestris, a very unusual, very powerful herb that has been shown in numerous studies to elevate testosterone levels. Most researchers and scientists believe it works by positively affecting levels of luteinizing hormone, which in turn positively affects levels of testosterone. Many companies market and sell various tribulus formations, but very few harvest the right parts of the plant at the right time of the year (certain parts of the plants, at certain times of the year, contain higher levels of saponins, the active ingredient). FGP?, a revolutionary flavone compound that was, until now, unavailable in the United States. Studies have shown that FGP, when given to chronically ill patients, caused them to gain between four and seven pounds of lean mass, without the benefit of resistance training or increased caloric intake. It's theorized that FGP works by inhibiting estrogen receptors at the hypothalamus, thereby causing the gland to produce more testosterone. Avena Sativa, a plant that has chemical properties that increase the levels of free testosterone in the body. These three components synergistically elevate testosterone levels higher than any other legal supplement on the market, and as high as certain illegal drugs. It's truly a steroid alternative. Each Capsule Contains: Tribulus Terrestris, 250 mg FGP (7-isopropoxyisoflavone aka ipriflavone), 100 mg Avena Sativa, 100 mg Saw Palmetto, 50 mg
