Winstrol (Stanozolol): The Pyrazole Oral

Winstrol is the oral that behaves least like one: it’s built on a pyrazole ring, which changes how it’s handled relative to the other tablets in the catalog.

The molecule

Stanozolol (C₂₁H₃₂N₂O, ≈ 328 g/mol) is a 17α-alkylated androgen with a fused pyrazole ring — the structural feature that sets it apart from oxandrolone and methandrostenolone. The 17α-alkylation is what makes it orally active: without it, the molecule is destroyed in first-pass metabolism. With it, the half-life drops to around 9 hours, which is why oral protocols dose daily or split the tablet.

Tablets, not vials

Unlike every lyophilized product in the catalog, Winstrol needs no reconstitution. It ships as 10 mg precision-dosed tablets — a 20 mg/day protocol is simply two tablets. The lab math that does apply is molar conversion when a method specifies concentrations, which the molecular weight calculator handles directly.

Research context

Stanozolol is referenced in SHBG-binding research and nitrogen-retention models. It’s one of three oral reference standards — the oral androgens comparison lines it up against Anavar and Dianabol, and the ester master reference shows where the orals sit in the kinetic table.

Practical notes

Room temperature storage, ethanol/oil soluble. See Winstrol for CAS, purity and specifications.
