Methandienone (also spelled methandrostenolone) is a synthetic androgenic–anabolic steroid that has been marketed under brand names such as Dianabol. It is structurally related to testosterone and is known for its strong anabolic properties.
Historically, Methandienone has been used in medical settings, but it later became widely recognized in bodybuilding circles due to its reputation for supporting rapid increases in muscle mass and strength. Its popularity has often been linked to its comparatively low cost and noticeable mass-gain effects during bulking-focused training phases.
Because Methandienone significantly affects hormone levels and carries potential health risks, its use should only occur under the supervision of a qualified healthcare professional.
