What is Winstrol?
Stanozolol (Winstrol) is a 17α-alkylated, pyrazole-fused DHT derivative with a unique heterocyclic A-ring structure. High anabolic activity with moderate androgenicity; does not aromatise. Notable for dramatically reducing SHBG — the strongest SHBG-displacing AAS. Research tool for SHBG biology, anabolic steroid pharmacology, and DHT-derived compound research. Research use only.
Research Applications
SHBG Displacement Research
Stanozolol SHBG affinity — most potent known SHBG displacer, free androgen models
Non-Aromatising AAS Pharmacology
Pyrazole-fused DHT structure — AR binding without estrogen conversion, tissue selectivity
Nitrogen Retention & Anabolism
Lean mass preservation, protein synthesis, anti-catabolic glucocorticoid receptor antagonism
17α-Methyl Hepatotoxicity
Oral AAS hepatic stress — cholestasis, ALT/AST, hepatocellular toxicity profiling
Lipid Profile Research
AAS-mediated HDL suppression, LDL elevation — cardiovascular risk biomarkers
