19-Nor-5-androstenedione , also known as estr-5-ene-3,17-dione , 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 .

19-Nor-5-androstenedione,
19-nor-5-androstenediol , 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 .
