For performance athletes, standard doses for men range between 25 and 50 milligrams a day. The most common dose is 25 milligrams taken orally or 50 milligrams injected. Such doses will produce solid results while allowing for control of side effects. In bodybuilders, the most common dose is 50 milligrams a day, with some going as high as 100 milligrams. Such high doses are not normally suggested outside of fitness models and bodybuilders, however, as side effects can become uncontrollable. If you are lean with body fat less than 10 percent , then these high dosages can produce an excellent physique for a show or competition. Do not take these high doses for more than seven to 10 days, however, because of the likelihood of cardiovascular and hepatotoxic side effects. Total use of Winstrol should not exceed two months , and then you should take a two-month break from this drug.
