Anastrozole that is mostly sold as Arimidex – oldest and most popular brand for Anastrozole (but can be found as many others) is an orally active Aromatase Inhibitor (AI) and therefore an effective anti estrogen. The compound has various medical uses but is also used among bodybuilders.

If you’ve been researching breast cancer compounds then you might have found out about Anastrozole. At the same time, if you’ve been researching compounds for bodybuilders, you still might have found out about Anastrozole.

It can be confusing, however, if you’re interested in “What is Anastrozole used for?” then you might check for more information below.

What Does Anastrozole Do?

Anastrozole is an AI, as mentioned, this means that it works by binding to aromatize enzymes and therefore is blocking the conversion into estrogen. Testosterone is converted into estrogen (part of it) through the process of aromatization.

When this process is stopped due to use of Anastrozole, which binds to those enzymes, the overall level of estrogen in the body starts to drop.

That’s why it is used for Estrogen Receptor Positive (ER+) breast cancer treatment and that’s why it is used by bodybuilders.

In both cases to suppress estrogen levels.

Anastrozole Uses In Medicine

Anastrozole (Arimidex) is used for treating breast cancer in women. It was found helpful for lowering the risk of cancer returning or spreading after surgery, for advanced or metastatic estrogen receptor positive or known breast cancer as well as a second line treatment in advanced or metastatic breast cancer in women who initially were treated with Nolvadex (Tamoxifen).

In medical settings, it has some other uses, but they are very rarely used. It can be used in men with naturally too high levels of estrogen, in treating ovarian cancer in women or early puberty treatment in boys.

In the end, Anastrozole is mostly used for treating breast cancer and that’s why it is considered a cancer drug.

In the medical industry, Anastrozole is seen as a breast cancer treatment compound, mostly.

Anastrozole Uses In Bodybuilding

Anastrozole For PCT

Because Arimidex – Anastrozole is lowering estrogen levels, there are less receptors that your hypothalamus receives and therefore, it makes your body produce more testosterone.

  • This is the reason why Anastrozole is sometimes used by bodybuilders to boost their testosterone levels as a Post Cycle Therapy (PCT) medicine after the use of anabolic steroids – to increase the suppressed levels of testosterone.What-Is-Anastrozole-Used-For-bodybuilding

Nonetheless, the compound is very rarely used for such purposes because it is considered a weaker testosterone booster compared to other compounds and in addition to that, it may suppress levels of estrogen too much during PCT which also comes with negative side effects and symptoms.

Anastrozole for PCT is used only in combination with other compounds and even so, is still very rarely used for Post Cycle Therapy needs.

Anastrozole For Estrogen Control

Instead, Anastrozole (Arimidex) is a very powerful, very effective and very popular compound for offering estrogenic protection during the cycle with aromatizable steroids.

Not all steroids convert into estrogen, but most bulking compounds do convert so you do need Anastrozole (or other form of AI) to stay away from estrogen related issues.

Anastrozole is used for keeping estrogen levels within normal levels during the use of anabolic steroids. That’s why it is a very popular (most popular estrogenic protection) compound on-cycle of aromatizable steroids.


  • It makes sure your levels of estrogen would be lowered and you won’t get too high estrogen levels and related side effects.

But be sure that Anastrozole (Arimidex) is a very powerful aromatase inhibitor and that’s why it can inhibit estrogen levels way too much. Is important to keep dosages in normal range (anastrozole dosage on-cycle is highly dependent on steroid dosage) to avoid too much suppression of estrogen.


Estrogen is a very important hormone both for women and men. It shouldn’t get over the roof (which is very likely during the use of steroids), but it shouldn’t be completely suppressed (which is very likely if abusing Anastrozole).

The levels should remain in the normal range for a proper body function.
