Aromasin by Zyvex Pharmaceuticals
What Is Aromasin?
Aromasin from Zyvex Pharmaceuticals is exemestane in a 20 mg tablet, 100 tablets per pack. Exemestane is a steroidal aromatase inhibitor: it permanently deactivates the aromatase enzyme that turns androgens into estrogen, so the effect lasts until the body builds new enzyme.
In cycle practice Aromasin is the on-cycle AI for aromatizing compounds, valued for the stable, rebound-free estrogen control that comes from its suicidal inhibition. It suits users who want fewer estrogen swings than with reversible AIs and who manage bloodwork through the cycle.
Aromasin Dosage
Exemestane is dosed every other day in most plans, with the 20 mg tablet split for the lower range.
| Situation | Dose | Schedule |
|---|---|---|
| Mild on-cycle control | 12.5 mg | Every other day |
| Standard testosterone cycle | 12.5-25 mg | Every other day Common |
| Heavy aromatizing run | 25 mg | Every day by bloodwork |
Estradiol bloodwork decides the real dose. Start at 12.5 mg EOD and only move up when a mid-cycle panel shows estrogen is still above range.

Aromasin Side Effects
Most Aromasin complaints trace to overshooting and driving estrogen too low, which is easy with a suicidal AI.
- Joints - dryness and soreness signal the dose is too high.
- Lipids - HDL can drop while on an AI.
- Recovery - AIs are not PCT tools; a SERM handles the restart after the cycle.

What is Aromasin?
Aromasin is the brand name for exemestane, a steroidal aromatase inhibitor. Zyvex Pharmaceuticals supplies it as 20 mg tablets, 100 per pack, for on-cycle estrogen control.
What does Aromasin do?
Exemestane permanently deactivates the aromatase enzyme, so estrogen cannot rebound the day after a dose. It is used on aromatizing cycles to keep estradiol in range.
What is the right Aromasin dosage on a cycle?
The reference dose is 12.5-25 mg every other day, adjusted by bloodwork. The 20 mg tablet is split for the lower range.
How often should you take Aromasin?
Exemestane is usually dosed every other day because its effect lasts longer than its presence in blood. Some protocols use 25 mg EOD as the standard.
How long does Aromasin stay in your system?
Exemestane has a half-life of about 24 hours, but its suicidal mechanism keeps aromatase blocked until the body builds new enzyme, which smooths the control.
How long does Aromasin take to work?
Aromasin lowers estrogen within days of the first dose. Full stabilization takes about two weeks as the enzyme pool is replaced.
Aromasin vs Arimidex: which is better for a cycle?
Aromasin is a suicidal AI with steadier, rebound-free control; Arimidex is reversible and faster to adjust. Both are used on cycle, and choice is often personal plus bloodwork.
Does Aromasin cause joint pain?
Joint and bone ache appears when estrogen goes too low. Dosing at 12.5 mg EOD and titrating by bloodwork keeps it comfortable.
What are the side effects of Aromasin?
The main effects are low-estrogen symptoms - joint ache, fatigue, libido drop - and mild lipid changes. Side effects are dose related.
