What is Anavar (Oxandrolone)?
Oxandrolone (Anavar) is a synthetic, C17-alpha-alkylated derivative of dihydrotestosterone (DHT), distinguished from most other anabolic-androgenic steroids by a comparatively mild androgenic profile relative to its anabolic activity, and by an unusual degree of oral bioavailability without the liver strain typically associated with 17aa compounds. Non-aromatizable (does not convert to estrogen via aromatase). Research tool for studying nitrogen retention, androgen receptor binding kinetics in muscle-wasting models, and structure-activity relationships among 17aa steroids. Bulk powder for large-scale AR pharmacology research. Research use only.
