Literature provided by the original maker of Anastrozole (Arimidex, produced by Zeneca Pharmaceuticals) states that stable blood plasma concentrations of the compound are achieved after a mere 7 consecutive 1mg daily doses.
When used to mitigate the estrogenic side effects of anabolic/androgenic steroid use, male athletes and bodybuilders will commonly take .5 mg to 1 mg of anastrozole per day. In some instances a half of a tablet (.5 mg) taken every other day is sufficient to mitigate the buildup of estrogen. When used with readily aromatizing androgens such as methandrostenolone or testosterone, gynecomastia and water retention are often effectively blocked. Additionally, the use of anastrozole may decrease fat mass, which can also be tied to estrogen levels. The result can be a harder and much more defined appearance to the muscles and physique, which makes this agent of interest for dieting/cutting purposes as well.
It is of note that food does not appear to affect the absorption of anastrozole, so the drug may be taken with or between meals.
