What is Winstrol?
Stanozolol (Winstrol) is a 17α-alkylated DHT-derived oral anabolic that does not aromatise to estrogen. Exceptionally high SHBG binding affinity. Research: androgen receptor studies without estrogenic confounds, SHBG biology, lean mass/body composition. CAS 10418-03-8.
Research Applications
Non-Aromatising Androgen
DHT derivative — no estrogen conversion — clean androgenic research
SHBG Binding
Exceptionally high SHBG affinity — displaces bound steroids
Anabolic:Androgenic Ratio
320:30 — high anabolic vs androgenic — tissue selectivity
Lean Body Composition
No water retention confound — body composition models
Hepatic Metabolism
17α-alkylated — ALT/AST, CYP450 interaction studies
