Stanozolol, also known by its trade name Winstrol, is a synthetic anabolic steroid that is a derivative of dihydrotestosterone (DHT). Below is a brief description of the substance and its characteristics:

Form: Stanozolol is available in both tablet (oral) and injectable (aqueous suspension) forms.

Purpose of use: Stanozolol is widely used in sports, especially in bodybuilding and sports requiring strength and endurance. It is also used in medicine to treat various medical conditions.

Anabolic properties: Stanozolol exhibits strong anabolic properties, meaning that it supports the processes of building and repairing muscle tissue.

Minimal aromatization: One of the distinctive features of Stanozolol is its minimal ability to aromatize, i.e. convert into estrogen. This makes it relatively low risk of estrogen-related side effects, such as gynecomastia or water retention.

Increased red blood cell production: Stanozolol can increase red blood cell production, which can contribute to improved oxygen transport to tissues and increased endurance.

Improved muscle hardness: Stanozolol is often used during periods of fat loss because it helps maintain muscle hardness.
