Like Androstenedione? "Androstenedione was manufactured as a dietary supplement, often called andro (or andros) for short. Sports Illustrated credits Patrick Arnold for introducing androstenedione to the North American market.[3] Andro was legal and able to be purchased over the counter, and, as a consequence, it was in common use in Major League Baseball throughout the 1990s by record-breaking sluggers like Mark McGwire.....Barry R. McCaffrey, the director of the White House's Office of National Drug Control Policy, attempted to determine whether androstenedione could be classified as an anabolic steroid in July 1999. However, he could not because there is no proof of it promoting muscle growth.....The "Andro-Project", conducted by medical researchers at East Tennessee State University, showed that the supplement "Andro"(androstenedione/androstenediol) does not increase muscle mass or strength.......A 2006 review paper summarized several studies that examined the effect of androstenedione on strength training. At dosages of 50 mg or 100 mg per day, andro had no effect on muscle strength or size, or on body fat levels. One study used a daily dosage of 300 mg of androstenedione combined with several other supplements, and also found no increase in strength when compared to a control group that did not take the supplements."
