Androstenedione is used to increase the production of the hormone testosterone to enhance athletic performance, increase energy, keep red blood cells healthy, enhance recovery and growth from exercise, and increase sexual desire and performance.
Androstenedione gained popularity as the supplement used by the baseball homerun hitter Mark McGwire and other professional sports players. In January 2005 legislation went into effect in the United States called the Anabolic Steroid Control Act of 2004. This reclassifies androstenedione from a dietary supplement to an anabolic steroid, which is a schedule III controlled substance.
Androstenedione is considered a banned substance by the National Collegiate Athletic Association (NCAA).
