What is Superdrol (Methasterone)?
Superdrol (Methasterone — injectable potent DHT-derived anabolic-androgenic steroid) is methasterone — C₂₁H₃₄O₂, MW 318.5 — formulated as an oil-based injectable at 50mg/mL. 2α,17α-dimethyl DHT derivative with exceptionally high anabolic activity and moderate androgenic activity. Does not aromatise to oestrogen. Originally released as a prohormone (2005); reclassified as a controlled AAS. Injectable format provides direct systemic delivery without first-pass hepatic metabolism.
