Arimidex 1mg x 50 Tablets


Arimigen, known as Anastrozole (or Arimidex), is classified as an Aromatase Inhibitor (AI) drug that is therapeutically used to treat breast cancer, but in the performance enhancement scene it is an invaluable non-steroidal ancillary drug used to mitigate estrogenic related side effects from aromatizing steroids. An aromatase inhibitor is recommended to use for most steroid cycles to avoid the onset of estrogenic side effects. Arimigen is a very strong aromatase inhibitor.



Arimigen, known as Anastrozole (or Arimidex), is a strong Aromatase Inhibitor (AI) and becomes invaluable while 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-androgenic steroid (AAS) compounds. Arimidex will significantly lower the body’s serum estradiol levels to a desirable level by inhibiting the aromatase process, mitigating the potential negative side effects. Most steroid cycles will 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 Evista (Raloxifene) would also be utilized to counter the existing estrogen from worsening and reverse the the side effects (gyno, water retention, erectile dysfunction, etc.).
