As a C17-aa anabolic steroid, Winstrol is hepatotoxic and will present stress to the liver. A common misconception many make is assuming only the oral version of this steroid is hepatotoxic. Winstrol can be found as an oral tablet or as an injectable solution but both forms are C17-aa and both stressful to the liver. In fact, injectable Winstrol is one of the only C17-aa injectable steroids. Many also inaccurately assume this is one of the most hepatotoxic anabolic steroids on the market; again this is false. Stanozolol will carry a greater hepatotoxicity than steroids like Anavar (Oxandrolone) but on a per milligram basis less hepatotoxic than steroids like Dianabol (Methandrostenolone).
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.
