QSC supplies six oral anabolic-androgenic steroids (AAS) as research-grade tablet kits (100, 500, and 1000-count). All ≥99% HPLC purity with Janoshik independent COA. Research applications include muscle wasting, body composition, androgenic signalling, hepatic metabolism, SHBG binding, and anabolic-to-androgenic ratio comparisons.

17α-Alkylation and hepatotoxicity
Dianabol, Winstrol, Oxandrolone, and Turinabol are 17a-alkylated — prevents first-pass deactivation but introduces hepatotoxicity in chronic models. Superdrol is not 17a-alkylated but hepatotoxic via alternate mechanism. This structural distinction is a key variable in hepatic metabolism research design.
