To strengthen the anabolic properties of testosterone, more than 100 synthetic steroid derivatives have been described for human purposes. The anabolic effect promotes protein synthesis, muscle growth and erythropoiesis. In clinical practice, substances with anabolic effect are needed to overcome various catabolic states. However, none of these compounds are devoid of androgenicity. Androgenic and anabolic properties of anabolic steroids cannot be totally separated. Therefore, it is more appropriate to use the term anabolic androgenic steroids (AAS).
Winstrol is a brand name of the synthetic anabolic steroid, stanozolol. Although no longer available in the . under the name of Winstrol, generic versions of stanozolol can still be found. Stanozolol is similar to testosterone and commonly used by veterinarians on debilitated animals (especially dogs and horses) to improve muscle growth, trigger red blood cell production, increase bone density and enhance appetite. It's approved by the . Food and Drug Administration (FDA) for treating anemia and hereditary angioedema (swelling of blood vessels) in people, although a prescription is needed. Winstrol (stanozolol) is a banned performance-enhancing drug, but still used widely by track and field athletes as well as bodybuilders — usually illegally. You should take stanozolol only with the permission and under the care of a physician.
As alluded to early on, the Stanozolol hormone is available in both an oral and injectable form. Both forms are simply Stanozolol and either will work, but there are a few slight differences. While the pill version has a half-life of about 9 hours, the injectable form has a half-life of a little less than 24 hours. Further, the injectable version is slightly more potent on a per milligram basis, but the difference in potency is negligible at best. In any case, the only difference of any worthy note is in the name. Winstrol pills are simply referred to as “Winstrol” whereas the injectable version is referred to as “Winstrol Depot.” Again, for all intense purpose they are both the same; just like the pill form, the injectable form is also a C17-aa anabolic steroid.
