Anavar is the trade name for oxandrolone, an oral anabolic steroid stemmed from Dihydrotestosterone. It was developed to have a really strong separation of anabolic and androgenic effect, and no considerable estrogenic or progestational activity. Oxandrolone is noted for being quite moderate as far as oral steroids are concerned, well tailored for the promotion of strength and quality muscle tissue gains without significant adverse effects. Milligram for milligram it shows as much as 6 times the anabolic activity of testosterone in assays, with significantly less androgenic. This drug is a favorite of dieting bodybuilders and competitive athletes in speed/anaerobic performance sports, where its propensity for pure tissue gain (without fat or water retention) fits well with the wanted goals.
