MeSH heading: Methandienone

Abstract
Methandienone is a synthetic anabolic‑steroid derivative of progesterone that has been widely used for performance enhancement in sports. Its structure confers high androgenic potency while limiting estrogenic conversion, leading to significant muscle hypertrophy and increased erythropoiesis. The compound’s pharmacokinetics are characterized by extensive first‑pass metabolism and a short half‑life (≈ 2–4 h) when administered orally; intramuscular injection yields a prolonged release due to depot formation. Adverse effects include hepatotoxicity, virilization in females, dyslipidemia, hypertension, suppression of endogenous deca durabolin dianabol testosterone cycle (https://www.valley.md/dianabol-cycle-benefits-and-risks) production, and potential cardiomyopathy. Detection methods involve liquid chromatography‑tandem mass spectrometry (LC‑MS/MS) targeting characteristic fragment ions of the steroid nucleus, often following solid‑phase extraction or derivatization to enhance sensitivity. In sports anti‑doping programs, its use is prohibited; violations result in bans ranging from 2 to 4 years depending on recurrence. The compound’s legal status is controlled under international drug schedules as a designer anabolic agent.
