Aromasin is the most popular brand of the active substance Exemestane. Regardless of the brand name (trade name) make sure you get Exemestane (of high quality) to ensure this product is working accordingly.

Aromasin (Exemestane) is working by blocking the effects of estrogen in the body. It lowers total estrogen levels in the body and this is why Aromasin is a powerful and popular tool in protecting against estrogenic side effects from steroids.

In medical settings, Aromasin is used for the same purpose of lowering estrogen. But usually, in women who are suffering from hormonally positive breast cancer. Those types of cancer form and grow due to estrogen. By adding Aromasin (Exemestane) and lowering estrogen, it helps treat breast cancer in women.

However, the fact that it lowers estrogen is very helpful for bodybuilders that are using anabolic steroids that are aromatizing. Some examples of such steroids are testosterone, nandrolone, methandrostenolone, and others. When you use those steroids, they convert into estrogen, thus causing estrogen side effects.

Aromasin (Exemestane) helps lower estrogen, thus protecting against those estrogen side effects.

Aromasin vs Other AIs

aromasin-pfizerExemestane – Aromasin is an aromatase inhibitor (AI) exactly as Anastrozole – Arimidex and Letrozole – Femara are. They are all working in similar ways and all leading to the same results. Aromatase Inhibitors are binding to the aromatase enzymes and block the conversion of other hormones into estrogen. This is why they all lead to lower estrogen levels in the body.

Nonetheless, Aromasin is still slightly different from the other two AIs. For example, it’s the only suicidal aromatase inhibitor. This means that it’s the only one that permanently disables the aromatase enzymes as soon as it binds to them. This is great because it excludes the risk of estrogen rebound.

That’s something that can occur with the other two aromatase inhibitors. Since they are not permanently disabling those aromatase enzymes, there’s a chance that estrogen would suddenly spike as soon as you stop the use. This could cause estrogen issues after stopping. However, it won’t occur with Aromasin (Exemestane).


Moreover, Aromasin is the only AI that lowers SHBG which is very helpful for a bodybuilder. It will also affect cholesterol levels less than the other aromatase inhibitors. Again, that’s very effective for steroid users who are already affecting their cholesterol due to the use of steroids. And because of SHBG binding affinity, Aromasin is great as a PCT medication (unlike the other two AI) and it won’t hurt your gains during the cycle as the other two might.

Exemestane and Estrogen

Exemestane, as I said, is binding very well to aromatase enzymes. This blocks the aromatization process, thus lowering estrogen levels. When using aromatizing (wet) anabolic steroids they are causing estrogenic side effects because you’re having a lot of hormones in your body that convert into estrogen.

Exemestane blocks this conversion, therefore, lowers the estrogen and the estrogenic side effects. When an individual uses aromatizing steroids, estrogen spikes.


High estrogen symptoms are:

  • Gynecomastia (enlargement of breast tissues in males) AKA – man’s boobs
  • Water retention
  • Hypertension (high blood pressure) is usually a result of water retention
  • Sexual dysfunction (low sex drive/ libido and/or erectile dysfunction)
  • Mental changes – feeling emotional, anxiety, depression, mood swings, and others

Therefore, Aromasin (Exemestane) is a great compound to deal with all these issues.

But on the other hand, remember that if you’re going to use way too much of this compound then it’s going to lower estrogen levels under the normal range. In this case, you’re also going to experience negative side effects and symptoms. But you’re going to get low estrogen symptoms (the common side effects of aromatase inhibitors).

Low estrogen symptoms are:

  • Mental changes – anxiety, depression, mood swings, and others
  • Joint and/or bone pains – estrogen is important for bone mineralization and health
  • Chronic fatigue and tiredness – estrogen is important for your central nervous system
  • Cholesterol issues – estrogen is important for the cholesterol health
  • Sexual dysfunction – although many consider it a female hormone, it’s important for a male too
  • Hinder strength and muscle gain – this hormone helps you grow muscle and get stronger

Therefore, these are the side effects of Aromasin and other AIs lowering estrogen.

How to Use Aromasin?

Use it carefully! This is a powerful aromatase inhibitor capable of lowering your estrogen too much! The point of using Aromasin (Exemestane) or any other AI is to keep estrogen within the normal range. Do not attempt to crush your estrogen because you’re going to suffer from the side effects I earlier mentioned.

The golden rule with any Aromatase Inhibitors including Aromasin is not to use them unless necessary (having high estrogen symptoms and/or can confirm high estrogen through blood work). If it’s necessary to use, go for the lowest effective dosage.

aromasin-bodybuilding-exemestane-uses Aromasin (Exemestane) comes in tablets usually of 25 mg per tablet. Bodybuilders do not need to use as high doses as females treating breast cancer. Moreover, they definitely don’t need to use it for as long as women do (a couple of weeks vs years). Lastly, women’s bodies are reacting differently to Exemestane (and other AIs) because of the estrogen role it plays in women’s vs men’s bodies.

That’s why the good news is that side effects are rarely a problem among bodybuilders. They generally split the tablets into two or even four mini doses of 12.5 mg or 6.25 mg per dose. The frequency of administration can be as rare as once a week (or even less frequent) or as frequent as every other day or, in rare cases, daily.

In order to determine the best dosage and frequency you have to make sure you understand how this product works for you. Experienced users already know how to dose it correctly, but those who are not having experience should start slowly and experiment with it to see how it affects them.

You need to take into consideration your personal response as well as the amount of aromatizing steroids that you use during the cycle.

In The End


Aromasin (Exemestane) is a powerful tool in dealing with anabolic steroids’ side effects. The estrogenic related ones. But it can cause its own side effects if you don’t use it correctly. It helps lower estrogen. Your duty is to keep estrogen within the normal range. Too high or too low levels of this hormone and you’re likely to experience side effects.
