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.

How it works?
Stanozolol is subject to non-medically supervised off-label use by some athletes for its anabolic properties frequently presenting with concomitant reduction of body fat. Stanozolol is a modified derivative of dihydrotestosterone (DHT) and thus not aromatized to oestrogens via the aromatase class of enzymes (see chemical structure to right). Bodybuilders frequently misuse the term "dry" in describing their joint pain while using stanozolol either orally or via IM injection of an aqueous suspension; a reference to their perceived reason for an increase in joint pain. Rather, stanozolol as a DHT derivative can selectively compete with progesterone and other natural and synthetic progestins (nandrolone) for progestin receptors; yielding a reduction in progesterone mediated anti-inflammatory processes and presenting patients with a perception of increased joint discomfort.

Dosages and Suggestion
The primary metabolites are unique to stanozolol and are detectable in the urine for up to 10 days after a single 5–10 mg oral dose.
