≥99% HPLC PurityMS ConfirmedJanoshik COA1-Region Domestic ShippingLow Androgenic Profile

What is Primobolan 25mg Tablets?

Primobolan (Methenolone Acetate) is an oral anabolic-androgenic steroid with a notably mild androgenic profile relative to its anabolic activity. The C1-methyl and 17-acetyloxy modifications produce moderate oral bioavailability and reduced 17α-alkylation-related hepatotoxicity compared to other oral AAS. Research applications include androgen receptor binding studies, lean mass preservation models, and comparative androgenic potency research where a low-androgenic anabolic comparator is required.

Research Applications

Androgen Receptor Binding Research

Methenolone acetate has characterised AR binding affinity — moderate anabolic, low androgenic ratio. Useful as a comparator in AR agonist selectivity studies.

Lean Mass Preservation Research

Low androgenic profile + anabolic activity makes Primobolan suitable for muscle preservation models in catabolic states (caloric restriction, glucocorticoid-induced atrophy).

Comparative AAS Pharmacology

Low hepatotoxicity profile makes Primobolan a useful comparator to assess androgenic vs hepatotoxic tradeoffs across the oral AAS class.
