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.⁴⁵
