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).
Anavar (Oxandrolone) is quickly becoming the steroid of choice of the casual steroid user. It has negligible side effects at reasonable dosages. It is a C-17 alpha-alkylated oral compound that seems to have less impact on the live and kidney than other oral steroids of this type. It does not convert to DHT so there is little concern for male pattern baldness, acne, or other related problems associated with DHT derived compounds such as Winstrol. The best thing with regard to this drug is that the gains made seem to be relatively permanent. Studies suggest that fat loss and lean mass gains seem to be kept for up to six month after cessation of use. Also, it seems to have less impact natural testosterone output in comparison to other steroids.
