Overview
Oral methenolone with acetate ester. Unlike most oral AAS, is NOT 17-alpha-alkylated, making it less hepatotoxic but also less orally bioavailable. The 1-methyl group provides partial protection from first-pass metabolism. Requires dosing 2-3x daily due to short half-life. Harm reduction: Lower liver toxicity than most oral AAS due to lack of 17-alpha-alkylation. Still monitor liver enzymes. Lower oral bioavailability means higher doses are needed compared to injectable Primobolan Depot.
Mechanism of Action
DHT derivative (1-methyl-5alpha-dihydrotestosterone) with acetate ester for oral administration. Not 17-alpha-alkylated — lower hepatotoxicity but reduced oral bioavailability.
