Bolandiol is on the World Anti-Doping Agency's list of prohibited substances,[5] and is therefore banned from use in most major sports. It is a potential metabolic precursor to nandrolone.[6] However, several clinical studies have concluded that bolandiol does not alter strength, body composition, or exercise performance.[7][8]
