Arimidex

Arimidex, the brand name for Anastrozole, is a prescription aromatase inhibitor (AI) used to control estrogen levels in both medical and performance-enhancement settings. It works by blocking the aromatase enzyme, which converts testosterone into estrogen — making it a crucial tool in steroid cycles that include aromatizing compounds like Testosterone, Dianabol, or Deca.
In bodybuilding, Arimidex helps prevent estrogen-related side effects such as gynecomastia, water retention, acne, and elevated blood pressure. It’s typically used on-cycle to maintain a balanced hormone profile.
