What is Stanozolol (Winstrol) Oil?

Stanozolol Oil (DHT-derived non-aromatising anabolic-androgenic steroid — oil-based injectable) is stanozolol — C₂₁H₃₂N₂O, MW 328.5 — formulated as an oil-based injectable solution at 50mg/mL. Oil-based stanozolol provides slower release and longer active window compared to the traditional aqueous suspension. 17α-alkylated DHT derivative with high anabolic/moderate androgenic ratio. Does not aromatise to oestrogen. Notable SHBG binding affinity.

Research Applications

DHT-Derived Non-Aromatising AAS

Stanozolol pharmacology without oestrogen co-effects — pure androgenic/anabolic signalling

SHBG Binding Research

High-affinity SHBG binding — free testosterone elevation co-administration studies

Oil vs Aqueous Depot Comparison

Extended-release oil-based stanozolol vs aqueous suspension pharmacokinetics

Lean Mass & Strength Research

Anti-catabolic and anabolic effects without water retention or oestrogen activity

17α-Alkylated AAS Pharmacology

Oral bioavailability modification in injectable format — comparative hepatic research

Frequently Asked Questions

How is this QSC injectable supplied?

QSC injectable solutions are supplied ready-to-use — no reconstitution required. Each vial contains the stated concentration in pharmaceutical-grade carrier (oil or aqueous). Draw using a sterile syringe appropriate for the solution viscosity.

How should this QSC injectable be stored?

Oil-based solutions: store at room temperature (15–25°C), away from direct sunlight — do not refrigerate as cold temperatures can cause crystallisation. Aqueous solutions: store at 2–8°C. Properly stored, injectable solutions are stable for 2–3 years.

What purity is this QSC injectable and how is it verified?

All QSC injectable compounds are ≥99% pure by HPLC on every production batch, with MS-confirmed identity. COA is published on the product page and independently verifiable at verify.janoshik.com.
