It is often said injectable Winstrol is far more powerful than its oral counterpart, and based on the increased enhancement of nitrogen retention this would support such a belief; however, it's not as cut and dry as you might think. Yes, injecting Stanozolol will increase nitrogen retention beyond what the oral tablet can; however, this increased enhancement is not that significant over the oral form; you can truly obtain the same results with either one. Another myth that often plagues injectable Winstrol surrounds its structural nature, most understand the oral tablet is a C17-aa steroid and assume the injectable form does not carry this hepatotoxic nature; they would be incorrect. Injectable Winstrol is one of the few injectable steroids that is a C17-aa anabolic steroid, and while its hepatotoxic nature is not quite as strong as the oral tablet it is still rather high; in-fact, both forms of Winstrol are some of the most hepatotoxic steroids on the market.
Stanozolol can stimulate the production of prostaglandin E2 and the matrix metalloproteases collegenase and stromelysin in skin fibroblasts. It has been found to inhibit growth factor stimulated DNA synthesis and fibroblasts. Winstrol has substantial fibrinolytic properties, and has been effective in the treatment of urticaria, Raynaud’s phenomenon, cryptofibrinogenemia, and lipodermatosclerosis. Stanozolol has also effected cures of osteonecrosis in cases resistant to all other therapy. Stanozolol has been used successfully in treatment of AIDS wasting syndrome.
Some bodybuilders and athletes use trenbolone esters for their muscle-building and otherwise performance-enhancing effects.  Such use is illegal in the United States and many other countries. The DEA classifies trenbolone and its esters as Schedule III controlled substances under the Controlled Substances Act .  Trenbolone is classified as a Schedule 4 drug in Canada  and a class C drug with no penalty for personal use or possession in the United Kingdom .  Use or possession of steroids without a prescription is a crime in Australia .  The infamous "duchess" cocktail allegedly administered to Russian athletes at the Sochi Winter Olympics consisted of oxandrolone , a metenolone ester, and a trenbolone ester.
