Aromasin, or Exemestane, is a potent aromatase inhibitor commonly used to reduce estrogen levels in the body, particularly during anabolic steroid cycles. It works by irreversibly binding to the aromatase enzyme, which blocks the conversion of testosterone to estrogen. This helps prevent estrogen-related side effects like gynecomastia, water retention, and fat gain. Aromasin is favored for its ability to maintain a stable hormonal balance, making it ideal for athletes and bodybuilders looking to control estrogen during cycles or hormone replacement therapy (HRT).
