Infobox references

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]
