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
Acetate ester oral delivery without alkylation hepatotoxicity
Mild Anabolic Reference
Low androgenic, moderate anabolic — lean tissue models
Comparative Hepatotoxicity
Reference mild oral AAS — liver studies vs 17α-alkylated
Body Composition
Lean mass maintenance — muscle wasting models
DHT-Derived / No Aromatisation
No estrogen conversion — clean anabolic studies
