19-Nor-5-androstenediol, also known as estr-5-ene-3β,17β-diol, is a synthetic, orally active anabolic-androgenic steroid (AAS) and a derivative of 19-nortestosterone (nandrolone) that was never introduced for medical use. [1] [2] [3] It is an androgen prohormone of nandrolone and of other 19-norandrostanes. [1] [2] [3]
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]
