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) .
Anabolic steroids are synthetic derivatives of testosterone . Nitrogen balance is improved with anabolic agents but only when there is sufficient intake of calories and protein . Whether this positive nitrogen balance is of primary benefit in the utilization of protein-building dietary substances has not been established. Oxymetholone enhances the production and urinary excretion of erythropoietin in patients with anemias due to bone marrow failure and often stimulates erythropoiesis in anemias due to deficient red cell production.
