What is Methasteron (Superdrol)?
Methasteron (Superdrol) is a 2α,17α-dimethyl-DHT derivative — a highly potent oral anabolic-androgenic steroid. Does not aromatise. Extremely high anabolic potency relative to androgenic activity. Research tool for high-potency non-aromatising oral AAS pharmacology and 17α-methyl hepatotoxicity studies. Research use only.
Research Applications
High-Potency Non-Aromatising AAS
Methasteron vs DHT, methylstenbolone — comparative anabolic potency without E2
17α-Methyl Hepatotoxicity
High-dose oral AAS hepatic stress markers — ALT/AST, cholestasis, DILI research
Anabolic:Androgenic Ratio
2α-methyl group contribution to anabolic selectivity — A:A ratio determination
AR Binding & Transactivation
High AR affinity, gene activation profile, coactivator recruitment
Oral Bioavailability Research
17α-alkyl first-pass resistance, hepatic metabolism, enterohepatic cycling
