Winstrol (active ingredient – stanozolol) is an anabolic steroid, which has two forms: tablets and injections.

It was synthesized and produced in 1962 in the scientific laboratory of Winthrop.

Stanazolol is a derivative of dihydrotestosterone, modified to enhance anabolic properties and reduce androgenic properties.

Stanozolol differs by the addition of the methyl group of 17-alpha to prevent the disintegration of the drug in the liver with oral administration, which is toxic to the liver, so that stanozolol has a low androgenic activity. Unfortunately, there is no scientific explanation, but stanozolol has the ability to antagonize progesterone receptors in the body, and inhibits the binding of glucocorticosteroids to their receptors.
