1. What is exemestane (Aromasin)?

Exemestane, sold under the brand name Aromasin among others, is a medication used to treat breast cancer. In certain breast cancers, estrogen fuels the growth of cancer cells. This is especially true after chemotherapy. Aromasin, as an aromatase inhibitor, is used to decrease the amount of estrogen in the body, thereby halting the growth or return of breast cancer.

While it was designed primarily for post-menopausal women trying to get rid of breast cancer, the fact that Aromasin powder can cut estrogen production has made it very popular with the bodybuilding and steroid-using communities.


2. How Exemestane powder works

Many breast cancers are stimulated to grow by the female sex hormones oestrogen and progesterone. These breast cancers are called hormone sensitive or hormone receptor positive. Blocking the effects of these hormones can treat breast cancer.

In women who have had their menopause, oestrogen is mainly produced by changing androgens (sex hormones produced by the adrenal glands) into oestrogens. This process is called aromatisation and happens mainly in the fatty tissues, muscle and skin. It needs a particular enzyme called aromatase.

Exemestane powder blocks the process of aromatisation. So it lowers the amount of oestrogen in the body. In early breast cancer, taking exemestane powder can help to stop breast cancer coming back. In advanced breast cancer, the cancer cells may grow more slowly or stop growing completely.


3. What Is Exemestane Used For In Bodybuilding?

Exemestane benefits is mostly known for controlling certain types of breast cancer in women. It lowers the estrogen levels in the body which are needed by the breast cancer tumors to grow. Although this is the most known benefit of using Exemestane powder, there are also other aromasin powder benefits that you enjoy for taking it. The no less popular was the product in sports, as it is able to effectively suppress the estrogenic side effects of anabolic steroids. Its mechanism of operation resembles the more popular aromatase inhibitors — Letrozole and Anastrozole. However, in contrast, athletes often use Exemestane powder in bodybuilding after a steroid cycle.

The product has an impressive active life of 48 hours, and if you miss a Exemestane powder dosage you have nothing to worry about, you only need to take the next dose the next day, and you are good to go.

Besides, the drug is said to be effective in protecting your body cells from damage to their DNA by the UV radiation during oxidation. Exemestane powder serves as an excellent anti-inflammatory agent.
