19-norandrostenedione

19-Norandrostenedione is a steroid that is an androgen precursor. It is a prohormone of nandrolone. Until the year 2005, 19-norandrostenedione 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 Agency.

Chemistry[edit | edit source]

19-Norandrostenedione is derived from androstenedione, from which it differs by the absence of a carbon atom at the 19th position. It is a precursor to nandrolone, a potent anabolic steroid.

Use in Supplements[edit | edit source]

19-Norandrostenedione was used in dietary supplements that were designed to increase the production of testosterone and muscle mass. However, the body's conversion of 19-norandrostenedione to testosterone is very low. It is more useful as a precursor to nandrolone.

Legal Status[edit | edit source]
