Otherwise known as Sarsaparilla root, this well know herb contains plant sterols which appear to stimulate the body's metabolic processes. Smilax Officinalis is believed to augment an athlete's performance during training and other situations whent he body is pushed to the max.
Contrary to popular belief, Sarsaparilla root does not contain testosterone. However, Sarsaparilla root has been used in the pharmaceutical industry as the starting material in the manufacture of semi-synthetic testosterone, and is believed by many herbalists (although not proven) to augment the body's natural production of its own testosterone.
