Arimidex (Anastrozole) is an extremely powerful anti-estrogen officially belonging to the Aromatase Inhibitor (AI) family. As an AI Arimidex functions by blocking the aromatase enzyme, which is in turn responsible for the production of estrogen. By inhibiting the aromatase process, Arimidex will lower the body’s serum estrogen levels. By including Arimidex in an anabolic steroid cycle that contains aromatizing steroids, the individual can protect against gynecomastia and water retention.
Dosages should be based on results from blood work but a typical dosage of 0.25-0.5mg every 2nd day is considered effective.
