That depends a lot on what your goals are. Typically, it is considered important for the sake of your health not to take the drug continuously. You will want some time away from the drug in order to give your body the time it needs to recover. This can be invaluable time for your liver to flush out toxins and return to a healthier state before you begin again. Consider a 10-week cycle of the drug. For the last two weeks, gradually reduce the dosage to help get your body off of it before stopping completely. This will help to reduce issues regarding side effects.
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.
