Exemestane is an active substance with a relatively complex chemical structure, being an aromatase inhibitor. Below you will find a brief description of Exemestane in points, along with its characteristics and use in bodybuilding:

Type of Substance:

Aromatase inhibitor.

Mechanism of Action:

Inhibits the activity of the enzyme aromatase, which converts androgens (e.g. testosterone) into estrogens.

Purpose of Use in Bodybuilding:

Control of estrogen levels during a steroid cycle.
Support of post cycle therapy (PCT).

Reduce Risk of Aromatisation:

Prevents aromatisation, the process by which testosterone is converted into estrogen, which can lead to undesirable effects such as gynaecomastia.

Post-Cycle Therapy (PCT):

To help restore natural testosterone production after the end of a steroid cycle, when the body may be susceptible to hormonal dips.


Individual and dependent on the purpose of use.
