Winstrol is used by bodybuilders especially in cutting cycles. It does raise the amount of testosterone circulating in the body and it does suppress other natural hormones levels, as well as change cholesterol levels. Most doctors limit its use to 6 weeks, although some people have used it for as long as twelve weeks. There are some reports that Winstrol weakens tendons and other reports say it strengthens them and other say it strengthens them unevenly, which could be an issue. Joint stress has also been reported while using Winstrol. It has become popular among women who want to build muscle mass and not gain fat. Anyone not involved in bodybuilding as a sport has alternatives when it comes to eliminating fat and building muscle mass.
