What is Primobolan (Oral)?
Methenolone Acetate (oral Primobolan) is a DHT-derived oral anabolic with the acetate ester enabling oral bioavailability without 17α-alkylation. Low hepatotoxicity relative to alkylated AAS. Anabolic:androgenic ~88:57. Research: mild anabolic studies with reduced hepatic risk, lean mass preservation, comparative non-alkylated AAS. CAS 434-05-9.
Research Applications
Non-17α-Alkylated Oral AAS
