Because the ultimate goal of a steroid cycle is to increase strength and muscle size, the associated spike in estrogen which accompanies steroids such as Testosterone is considered undesirable. In order to disassociate the two effects, two classes of drug are used. Medications such as Nolvadex or Clomid target the estrogen receptors. They make it more difficult for the estrogen to exert it’s influence within the body thus allowing the testosterone to act more freely. The second class is aromatase inhibitors such as Femara. They target the aromatase enzyme itself in order to prevent the production of estrogen in the first place. Sometimes, it’s not always clear which option you should go with or even what the differences are between the two. Lets clear that up a little.
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.
