19-Nor-5-androstenediol, 19-nor-5-androstenedione, and other 19-norandrostane prohormones were considered to be nutritional supplements and were sold over-the-counter in the United States as a result of the Dietary Supplement Health and Education Act of 1994 (DSHEA).[1][2] However, they were banned from sports in 1999 by the International Olympic Committee (IOC) and are currently on the World Anti-Doping Agency (WADA) list of prohibited substances.[1] In 2004, they became controlled substances in the U.S. as a result of the Anabolic Steroid Control Act of 2004.[1]
