Arimidex, also referred to as Anastrozole or Adex, falls under the category of Aromatase Inhibitor (AI) medications. In the medical context, it serves as a valuable tool in the treatment of breast cancer. However, within the realm of performance enhancement, it plays a crucial role as a non-steroidal ancillary drug to counteract the estrogenic side effects associated with aromatizing steroids. Using an aromatase inhibitor is generally recommended during most steroid cycles to prevent the emergence of estrogen-related side effects, and Arimidex is renowned for its potent aromatase inhibiting properties.
What is Arimidex?

Arimidex, also known as Anastrozole, serves as a potent Aromatase Inhibitor (AI) and plays a crucial role when incorporating aromatizing compounds into steroid cycles. While Selective Estrogen Receptor Modulators (SERMs) work by binding to estrogen receptors to block estrogen from attaching to them, Aromatase Inhibitors (AIs) operate differently. They hinder the initial formation of the aromatase enzyme, a byproduct often associated with the use of most anabolic-androgenic steroid (AAS) compounds.

By inhibiting the aromatase process, Arimidex effectively reduces the body’s serum estradiol levels to a desirable range, thus mitigating potential negative side effects. In the context of most steroid cycles, the inclusion of an AI is essential to prevent elevated estrogen levels and the accompanying adverse effects. If these effects have already materialized, a Selective Estrogen Receptor Modulator (SERM) such as Evista (Raloxifene) may be employed to counteract existing estrogen-related issues like gynecomastia, water retention, and erectile dysfunction.
