A lot of bodybuilders consider Anasteron (Oxymetholone) to be the strongest oral that there is for sheer mass gain. It is important to note that some of this mass will be from water bloat caused by the steroid. While Oxymetholone is a DHT derived compound and therefore can’t convert directly to estrogen, it still is known for many estrogenic related side effects. Some have speculated that Oxymetholone somehow triggers the body’s natural estrogen receptors into overdrive. Stronger anti-estrogens such as Letrozole and Exemestane have been shown to greatly suppress the body’s estrogen levels and can both be very effective in keeping these types of side effects to a minimum while using Anasteron (Oxymetholone) .
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).
