Winstrol or stanozolol is a synthetic anabolic steroid which resembles testosterone. Stanozolol is both an anabolic and androgenic hormone. In females it does cause virilizing effects.
Once widely available on the market, today it is a difficult product to find. Despite the hype on cyberspace about Winstrol being available, there have been many incidences of fake formulations or contaminants in products bought over the internet.
The lure of easy money has gotten many people in the business of selling fake anabolic steroids on cyberspace. And the DEA closely monitors each site because the selling and distribution of any anabolic steroid is illegal. Many Winstrol products sold over the internet have been analyzed and found to contain harmless cholesterol like molecules with contaminants. So for the bodybuilder interested in anabolic steroids, the internet is not is not the place to buy the drug as the purity cannot be established.
