One of the most popular steroids on the planet, Winstrol not only possesses large popularity but a bit of infamy as well thanks to athletic steroid scandals in recent history; most notably Ben Johnson and the 1988 Olympic Games. Not only is this steroid popular among bodybuilders and power lifters it is a longtime favorite of a host of various professional athletes, largely in-part due to its versatility. While most will use this anabolic steroid in cutting cycles it can be a solid addition to a bulker as well. Unlike the previously mentioned horse steroids this one can absolutely be found in human grade. While it is of both human grade nature and vet grade this anabolic steroid is not uncommonly used in horses, thereby giving it somewhat of an honorary title in the horse steroid camp.
