Bolandiol (19-norandrostenediol) is a synthetic anabolic steroid. It is hypothesized by interaction with androgen receptors, estrogen receptors, and progestin receptors.[1]

Bolandiol is on the World Anti-Doping Agency's list of prohibited substances,[2] and is therefore banned from use in most major sports. It is a potential metabolic precursor to nandrolone.[3] However, several clinical studies have concluded that bolandiol does not alter strength, body composition, or exercise performance.[4][5]
