In most cases a good Winstrol cycle will run for approximately 6-8 weeks at a dosing of 50mg every day. Some will find 50mg every other day to be all they need but as this anabolic steroid has a very short half-life, especially in tablet form daily administration is generally best. 50mg per day appears to be perfect for most any man regardless of his level of experience and we do not recommend going beyond the 8 week mark as this steroid is rather liver toxic. Winstrol is one of the more hepatic anabolic steroids we will ever use but thankfully if used responsibly the liver will return to normal values very quickly after use has been discontinued. The only exception we might make regarding the dose of a Winstrol cycle is for the competitive bodybuilder towards the very end of his contest prep cycle. Many bodybuilders find 100mg per day the last 10-14 days before a show to be very useful in-terms of really hardening them up before they step on stage; however, 14 days is the maximum recommended duration for such a dose due to the toxicity of this steroid.
Stanozolol appears to offer less hepatic stress than an equivalent dose of Dianabol (methandrostenolone). Studies giving 12mg of stanozolol per day for 27 weeks failed to demonstrate clinically-significant changes in markers of liver function, including serum aspartate amino-transferase, alanine amino-transferase, gamma-glutamyltransferase, bilirubin, and alkaline phosphatase. 621 Relative hepatotoxicity increases as the dosage escalates, so hepatic dysfunction should still be a concern. In rare instances, high doses (alone or in combination with other steroids) have been implicated in cases of serious life-threatening hepatotoxicity in bodybuilders. Injectable stanozolol has also been implicated in severe hepatotoxicity in an otherwise healthy bodybuilder, 622 and should not be used as an alternative medication when liver toxicity precludes oral stanozolol use.
