Compound type: DHT-Derived Anabolic-Androgenic Steroid — Non-Aromatising AR Agonist CAS Number: 10418-03-8
What is Stanozolol (Winstrol)?
Stanozolol is a synthetic 17α-methylated dihydrotestosterone (DHT) derivative with a unique pyrazole ring fused to the A ring. It binds androgen receptor (AR) with moderate affinity and does not aromatise to oestrogen (no CYP19A1 substrate activity). Stanozolol potently reduces SHBG binding affinity, increasing free androgen fraction in models. It also demonstrates unique anabolic activity on collagen synthesis via glucocorticoid receptor (GR) antagonism at the tendon. Oral tablet and injectable (oil and water-suspension) forms studied for comparative pharmacokinetics.
Research Applications

Quick Specs
Form
Oral tablet / Injectable oil or aqueous suspension
Stanozolol (Winstrol) is a synthetic DHT-derived anabolic-androgenic steroid with a unique pyrazole A-ring. It is a non-aromatising AR agonist studied for lean anabolism, SHBG displacement, and collagen synthesis research. Available in oral tablet and injectable forms.
How is injectable Stanozolol supplied?
QSC injectable Stanozolol is available in both oil-based and aqueous suspension forms. Both are ready-to-use — no reconstitution required. Shake the aqueous suspension well before drawing. Warm oil-based solutions briefly before drawing to reduce viscosity.
What purity is QSC Stanozolol?
QSC Stanozolol is ≥99% HPLC pure with MS-confirmed identity on every batch. COA is published on the product page and verifiable at verify.janoshik.com.
