Winstrol is the most widely recognised trade name for the drug stanozol. Stanozol is a derivative of dihydrotestosterone and its classified as an “anabolic” steroid and it cannot be aromatized into estrogens. Winstrol is the second mostly widely used oral steroid, succeeded in popularity only by Dianabol. It is favoured for its ability to promote muscle growth without water retention making it highly valued by dieting bodybuilders and competitive athlets.
Stanozol is widely available in both human and veterinarian drug markets. Comosition and dosage may vary by country and manufacturer. Even that Stanozol is not aromatized by the body and its not highly estrogenic it is known to strongly suppress levels of SHBG. An anti oestrogen is not necessary when using this steroid while gynecomastia should not be a concern even among sensitive individuals.
Winstrol is very popular among athlets in combination of strength/speed sports such as track and field where in such disciplines one usually does not want to carry excess of water weight.
