Stanozolol, commonly sold under the name Winstrol (oral) and Winstrol Depot (intramuscular), is a synthetic anabolic steroid derived from dihydrotestosterone. It was developed by Winthrop Laboratories (Sterling Drug) in 1962, and has been approved by the FDA for human use. Stanozolol is a17-alpha-alkylated anabolic steroid with good oral bioavailability. While Stanozolol’s androgenic activity index is nearly the same as testosterone, its myotrophic activity is much higher at 2.0:3.7. Stanozolol does not aromatize and does not cause water retention.

Stanozolol has been used for weight loss management in HIV patients with chronic obstructive pulmonary disease and has showed significant improvement in weight, body mass index, LBM, and muscle size. Stanozolol has been shown in-vitro to significantly enhance collagen synthesis. A positive effect of Stanozolol on wound healing in patients with non-healing wounds has also been demonstrated. Clinical studies show that the treatment with Stanozolol during the induction phase of chemotherapy results in a positive effect on the duration of cancer-free remission.
