Most people who are new to the fitness industry find themselves asking, what is Winstrol? Winstrol is the brand name of Stanozolol, an anabolic and androgenic steroid that is derived from dihydrotestosterone. Winstrol is the common name for the oral formulation while the parenteral formulation goes by the name, Winstrol Depot. It is one of the few anabolic steroids that can be used by both males and females. This is because it has less virilizing properties on females as compared to the other steroids available in the market.
Winstrol reduces circulating sex hormone binding globulin, the hormone that is responsible for scavenging testosterone. In so doing, there are greater levels of circulating endogenous testosterone. The other mechanism of action is to mediate and increase protein synthesis with nitrogen retention. It also has an effect on erythropoietin leading to increased production of red blood cells that is equivalent to increasing oxygen delivery to the muscles.
Despite the effect on protein synthesis, Winstrol is not a bulking agent. It has been shown to have a significantly low ability to increase muscle mass. However stacking with other bulking steroids is effective. This is because of its effect on the sex hormone binding globulin. Winstrol is usually used during the cutting phase of training. During this phase, there is preservation of lean body mass with reduction in fat stores in the body.
Unlike other steroids, Winstrol does not aromatize to estrogen. The end result is reduced water retention. As a result, there is a lower risk of increased blood pressure associated with the use of this steroid. Winstrol is more of a performance enhancer than muscle builder. Its main benefits are increasing exercise tolerance and overall strength due to better oxygenation of the muscles.
Due to its inability to undergo aromatization, Winstrol is beneficial in that the estrogenic side effects that are associated with other anabolic steroids are nonexistent. Androgenic side effects are however common. This includes rapid hair loss in those with genetic predisposition to male pattern balding and reduction in the good cholesterol, high density lipoproteins. The side effects regress with stopping the use of Winstrol.
