Arimidex Bodybuilding

Illegally, Arimidex may be used by bodybuilders to block estrogen. Arimidex may help prevent side effects such as gynecomastia (male breast enlargement) from developing due to the aromatization of anabolic steroids. The idea is that by suppressing estrogen's effects in the body, you can enhance testosterone's, and even increase total testosterone levels by reducing the amount that's naturally converted into estrogen. This, in turn, is supposed to increase muscle growth.

Some bodybuilders use Arimidex to control gynecomastia, which is a side effect of taking anabolic steroids. It causes males to grow breasts. Arimidex can have several side effects and is usually a treatment for breast cancer. It is not advisable for people to take Arimidex for bodybuilding.

Arimidex for Gyno

Bodybuilders who take anabolic steroids to try to increase muscle mass and improve athletic performance can experience a range of symptoms. In some cases, males might start to grow breasts due to an increase in estrogen levels. Arimidex lowers estrogen levels and can prevent breast growth in males. However, the drug also has side effects of its own.

Arimidex belongs to a category and class of drugs known as aromatase inhibitors (AIs). Aromatase inhibitors belong to an even broader class of drugs known as anti-estrogens. The other subcategory of drug under the anti-estrogens category is known as selective estrogen receptor modulators (SERMs), such as Nolvadex and Clomid.
