What is Superdrol?
Methasterone (Superdrol) is a 2α,17α-dimethyl DHT-derived oral anabolic steroid — non-aromatised, high anabolic:androgenic ratio (~400:20). Despite lacking classical 17α-alkylation, it is highly hepatotoxic via an alternative mechanism. Research: high-potency non-aromatising anabolism, hepatotoxicity mechanism studies. CAS 3381-88-2.
Research Applications
High-Potency Non-Aromatising
~400:20 anabolic:androgenic — no estrogen conversion
Hepatotoxicity Mechanism
Severe hepatotoxic without classical 17α-alkylation — mechanism research
Anabolic Potency
High anabolic index — acute hypertrophy and MPS models
Lean Body Composition
Rapid lean mass accrual, minimal water retention
Comparative AAS
High-anabolic/low-androgenic non-aromatising reference
