Arimidex is classified as an Aromatase Inhibitor (AI) drug that is therapeutically used to treat breast cancer. In the performance enhancement scene Arimidex is an invaluable non-steroidal ancillary drug used to mitigate the estrogenic side effects from aromatizing steroids. An aromatase inhibitor is recommended to supplement with for most steroid cycles to avoid the onset of adverse side effects.



Arimidex (1mg x 50)

Arimidex (Arimigen), known as Anastrozole, is a strong Aromatase Inhibitor (AI) drug which becomes invaluable to supplement with for those running steroid cycles with aromatizing compounds. Where SERMs bind to estrogen receptors, effectively blocking estrogen from binding to them, Aromatase Inhibitors (AIs) function by blocking the initial formation of the aromatase enzyme, which is a byproduct of administering most anabolic steroids. Arimidex will significantly lower the body’s serum estradiol levels to a desirable level by inhibiting the aromatase process, mitigating the potential adverse side effects. Most steroid cycles require an AI to prevent elevated estrogen levels and the related side effects. If the effects have already manifested, then a Selective Estrogen Receptor Modulator (SERM) such as Raloxifene should also be utilized to counter the existing elevated estrogen levels from worsening and to reverse the developed side effects (gynecomastia, water retention, erectile dysfunction, etc.).
