Exemestane, marketed as Aromasin, is a potent steroidal aromatase inhibitor developed by Pharmacia & Upjohn and approved by the FDA in 1999. It effectively reduces estrogen levels by inhibiting the enzyme responsible for estrogen synthesis, making it valuable in breast cancer treatment. Bodybuilders use it off-label to combat estrogenic side effects from steroid use, such as gynecomastia and water retention. Exemestane lowers serum estrogen levels by approximately 85%, helping athletes maintain a leaner, more defined physique during cycles .
