ARIMIDEX® (Anastrozole) is an extremely powerful anti-estrogen officially belonging to the Aromatase Inhibitor (AI) family. Arimidex has proven to be very effective in breast cancer treatment, even more so than traditional Nolvadex (Tamoxifen Citrate), and is a favorite anti-estrogen among many anabolic steroid users. Countless anabolic steroid users rely on Arimidex on cycle for estrogenic protection. Many anabolic steroids have the ability to aromatase and lead to excess estrogen, which in turn can lead to some of the most commonly associated side effects of anabolic steroid use. The functions and traits of Arimidex although powerful are extremely simple. As an aromatase inhibitor, 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; in fact, a total suppression of estrogen by 80% has been well noted with this aromatase inhibitor. This will prove extremely valuable to many anabolic steroid users. Arimidex also has the ability to stimulate the release of Luteinizing Hormone (LH) and Follicle Stimulating Hormone (FSH), those two hormones essential to natural testosterone production.
