# Winstrol (Injectable)

*Also known as: Winstrol Depot, Stanozolol Inj*

Injectable stanozolol suspension; micro-crystals give a long apparent peak.

## Overview

Winstrol injectable (Winstrol Depot, stanozolol aqueous suspension) is an injectable form of stanozolol, a DHT-derived anabolic steroid supplied as a microcrystal water suspension rather than an oil-based ester. Those microcrystals dissolve slowly at the injection site, which is what gives the depot its extended release and its unusually long apparent peak. Stanozolol binds the androgen receptor, does not aromatize, and is used as a cutting or performance agent prized for strength without water retention. The dataset records a half-life of about 82 hours (3.4 days), Cmax near 600 ng/dL, and 100% nominal bioavailability. Documented protocols inject it every other day to match that depot profile. Hepatotoxicity is rated mild for the injectable (lower than oral), and joint pain is a commonly reported downside.
