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).
Of course, we said there were two testosterone related Winstrol side-effects , the first being testosterone suppression and the second being testicular atrophy. As testosterone is manufactured in the testicles, when production is suppressed the testicles simply atrophy. They do not shrink and disappear; in-fact, in some cases the difference may not be all that noticeable. When we’re speaking of testicular atrophy we’re simply referring to the testicles losing some of their fullness. Once the use of all anabolic steroids has been discontinued and all the hormones are out of your system natural testosterone production will begin again, and your testicles will return to their normal size.
