Bolandione, also known as 19-norandrostenedione, as well as 19-norandrost-4-en-3,17-dione or estr-4-ene-3,17-dione, is a precursor of the anabolic-androgenic steroid (AAS) nandrolone (19-nortestosterone). Until 2005, bolandione was available without prescription in United States, where it was marketed as a prohormone, but it is now classified as a Schedule III drug. It is also banned from use in many sports, including the Olympic Games, under the World Anti-Doping Code. Bolandione is readily metabolized to nandrolone after oral administration, but its potency to transactivate the androgen receptor dependent reporter gene expression is 10 times lower as compared to dihydrotestosterone (DHT).
