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
