Aromasin is the brand name of the active substance Exemestane (any other brand with the same active substance is the same Aromasin, but sold under different trademarks) and this is an orally active medication that is medically used and FDA approved for treating breast cancer in women. If you’re familiar with Arimidex (Anastrozole) then you should know that Aromasin (Exemestane) is very similar to this compound and you can expect similar results.

There are some differences between the 2 drugs, yet final results would be pretty much the same.

Both Arimidex and Aromasin are classified as Aromatase Inhibitors (AIs) because they are both very effective at inhibiting the aromatization process in the body.

The compound is used to lower total estrogen levels in body.

Therefore, in medical settings that helpful for women who suffers from estrogen receptor positive (ER+) breast cancer but in bodybuilding industry, is used during the use of anabolic steroids (aromatized steroids, also known as wet steroids) to prevent high estrogen levels and the related side effects.

Aromasin vs Arimidex

Taking into consideration that Arimidex is so popular, why would someone need Aromasin?

Well, AromasinExemestane is a suicidal aromatase inhibitor (AI) and that’s the main difference between Exemestane and Anastrozole. This means that unlike Anastrozole (which is a non-suicidal aromatase inhibitor) that only binds to aromatase enzymes when the drug is present in the body, Aromasin is permanently disabling the aromatase enzyme.

This offers Aromasin the great advantage of not allowing estrogen rebound that is possible to happen with other popular AIs such as Arimidex or Femara which temporarily stop estrogen from aromatizing.

At the same time, AromasinExemestane is more powerful than ArimidexAnastrozole.

  • This gives the advantage of better suppression of estrogen in emergency situations, but the disadvantage is that Anastrozole is easier to control in terms of side effects – plus is cheaper.
  • However, to make sure estrogen is suppressed and you won’t get estrogen rebound after the cycle, is worth the extra money for Aromasin.

Aromasin in Bodybuilding


Keep in mind that not all anabolic steroids aromatize (those that don’t are considered dry steroids – non aromatizable ones) .

But a lot of steroids do convert to estrogen and those are mostly bulking compounds that help you grow muscles, but using them requires adding an AI to prevent or treat high estrogen related issues that are possible to occur due to use of steroids.

If running these compounds without estrogenic protection, you are likely to get a spike in estrogen and this would offer different side effects. Some of the most common ones include: water retention, heart issues, high blood pressure, gynecomastia and others.

Aromasin Side Effects

If AromasinExemestane is used properly, side effects are almost unheard of among bodybuilders during the use of steroids. Remember the compound is used in order to combat the negative side effects, not to offer you new ones.

In the end, side effects are more likely to occur from use of steroids without AIs, than from the Aromasin when used properly.


If you get side effects from Aromasin (Exemestane) it means that you most likely use too much and dosages should be reduced.

  • NOTE! Females needing Aromasin for breast cancer are more likely to get side effects than bodybuilders for steroid cycles.

Too high dosages eliminates too much estrogen and this might lead to negative side effects such as dry out joints, low energy, mood and sex drive, inability to grow muscles and gain strength and others.

Aromasin Administration

As mentioned, this compound comes in the form of oral pills. The half life of Exemestane is around 25 hours, that’s why you can use tablets on a daily basis or even every other day.

Is recommended to start at a lower dose and then to increase only if needed, and increase according to your needs (due to reasons above explained).

Aromasin dosage is highly dependent on the steroid dose.

Most men start at a dosage of 12.5 mg every other day. They may increase to 12.5 mg every day or 25 mg every other day if they don’t get enough estrogenic protection. Doses might be upped to 25 mg on a daily basis if required.

Is recommended to have blood work done to check your levels of estrogen and determine how exactly to run AromasinExemestane dosage.

Start slowly and increase slowly only if required. Stay at the absolute lowest effective dosage. If aromasin-exemestane-odin-pharma side effects start appearing – reduce the dosage.
