Overview

Aromasin is exemestane, a steroidal aromatase inhibitor used for breast cancer after menopause.

How it works

Exemestane binds aromatase permanently (a suicide inhibitor), so the body must make new enzyme before estrogen production recovers.

Chemistry

From PubChem, the US National Library of Medicine’s chemistry database.

Exemestane

Formula: C₂₀H₂₄O₂
Molecular weight: 296.4 g/mol
CAS: 107868-30-4
PubChem CID: 60198 ↗

Clinical reference

The breast-cancer label amount is 25 mg once a day after a meal. Off-label use in men is much lower and should follow estradiol bloodwork.

Label and guideline amounts are shown for reference only. They are not a recommendation, and we never give cycle or performance amounts. Any use belongs under a doctor’s care, with bloodwork.

Thanks, Brian! Estrogen control works best guided by bloodwork rather than by habit. Appreciate the review.
