Winstrol is hepatotoxic, and because of this, it should be used at the lowest effective dose for the shortest possible cycle. What’s more, you should consider using a supplement designed to provide some additional protection. Milk thistle is a highly recommended option; studies suggest it can provide an effective layer of protection when it is used for the entire length of your cycle. There are some other supplements on the market, such as Liver Care, which are blends of natural ingredients that have been shown to work together to prevent liver toxicity.
If long acting esters were used, then the existing drug from the heavy phase will have significant anabolic effectiveness for 2-3 weeks after injection, depending on dose, and thus no injectables would need to be used in those weeks. After that point, if Primobolan is not available, one might wish to continue with once-a-day dosing of orals or very low dose (100 mg/week) testosterone with use of anti-estrogens . A balance must be struck, however: there is a middle ground that we do not want to be in. There is a range where there is still some anabolic support yet there is fairly little inhibitory effect, but past this range, there still is not great anabolic effect, but there is substantial inhibition. One does not want to spend more time than necessary in this middle ground, but pass through it relatively quickly. Once in the light phase, the dose must remain low enough to allow recovery of natural hormone production to occur.
