Aromasin

Name: Aromasin
Brand: Quanta Pharmaceuticals

Exemestane, a steroidal aromatase inhibitor studied for suppressing oestrogen conversion during PCT protocols.

Aromasin (Exemestane) is a steroidal aromatase inhibitor studied extensively for its ability to suppress the conversion of androgens to oestrogen. This formulation supplies 50 tablets of 12.5mg per tub. Chemically classified as C20H24O2, Exemestane is structurally similar to androstenedione, aromatase's natural substrate — a resemblance that lets the enzyme mistake it for the real thing. It works as a suicide substrate: the enzyme processes it partway, generating a reactive intermediate that permanently binds and deactivates the active site. This irreversible mechanism distinguishes it from non-steroidal aromatase inhibitors and has made it a frequent subject of post-cycle and oestrogen-management research. With an elimination half-life of roughly 18-24 hours, Aromasin supports once-daily research dosing and stable suppression of aromatase activity across a study protocol.

Research Benefits

Oestrogen Suppression — Studied for irreversibly deactivating the aromatase enzyme, lowering oestrogen conversion.
Post-Cycle Support — Frequently included in research protocols examining hormonal recovery.
Gynecomastia-Related Research — Investigated for its role in managing oestrogen-driven side effects.
Favourable Lipid Research — Some studies suggest a comparatively neutral effect on lipid markers relative to other aromatase inhibitors.
Stable Once-Daily Dosing — A 24-hour half-life supports consistent enzyme suppression across a protocol.

How It Works

Exemestane is a steroidal aromatase inactivator that binds irreversibly to the aromatase enzyme's active site, acting as a suicide substrate. Once bound, the enzyme is permanently deactivated, meaning new aromatase must be synthesised before activity can resume.

This irreversible mechanism distinguishes Exemestane from non-steroidal aromatase inhibitors, which bind reversibly. Research has focused on its use in suppressing oestrogen conversion during hormonal-support and post-cycle protocols, with a roughly 24-hour half-life supporting stable, once-daily dosing.
