Exemestane is an inhibitor of antiestrogen and aromatase. It is the only known ‘suicidal ‘steroidal aromatase inhibitor, meaning that its action is irreversible. Aromasin is similar in structure to the natural substance androstenedione.

The effects:

• Prevents estrogen-related side effects;
• Restores the endocrine profile quickly;
• Improves appetite and sleep.

Bodybuilders usually use Aromasin during the cycle or after it to restore natural testosterone production and save muscle mass gained during the cycle.
