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 males with delayed puberty: Various dosage regimens have been used; some call for lower dosages initially with gradual increases as puberty progresses, with or without a decrease to maintenance levels. Other regimens call for higher dosage to induce pubertal changes and lower dosage for maintenance after puberty. The chronological and skeletal ages must be taken into consideration, both in determining the initial dose and in adjusting the dose. Dosage is within the range of 50 to 200 mg every 2 to 4 weeks for a limited duration, for example, 4 to 6 months. X-rays should be taken at appropriate intervals to determine the amount of bone maturation and skeletal development (see INDICATIONS AND USAGE and WARNINGS ).
