Stanozolol is a synthetic anabolic-androgenic steroid derived from dihydrotestosterone. It binds to androgen receptors and has both anabolic and androgenic activity.

The compound has had historical medical applications, although its modern use is also associated with non-medical performance enhancement. Injectable and oral formulations can differ in pharmacokinetic characteristics and formulation requirements.

Stanozolol can influence liver function, lipid levels, endogenous hormone production, and cardiovascular health. The precise concentration and excipients of an injectable product should be established from its actual labeling rather than assumed from the product name.
