2. Letrozole Features:

 

Letrozole is approved by the United States Food and Drug Administration (FDA) for the treatment

of local or metastatic breast cancer that is hormone receptor positive or has an unknown receptor

status in postmenopausal women. Letrozole is intended for use only by women who are no longer

of childbearing age. Possible candidates must have already ceased to menstruate. It is often used

in patients who have already undergone other cancer treatments, such as radiation, chemotherapy,

and used other cancer drugs, like tamoxifen. This nonsteroidal aromatase inhibitor may help prevent

any remaining cancer cells from spreading.

4. Letrozole Application:

1). Femera, commonly known as Letrozole is an anti-estrogen medication more aptly labeled an aromatase inhibitor (AI.)

2). Originally developed in the fight against breast cancer, the purpose of Letro as it is often called

is to reduce and inhibit estrogen buildup as excess estrogen has been directly linked to breast

cancer; often the medication is given to patients as part of their post-surgery therapy.

3). Letrozoleis not an anabolic steroid in any shape or form but belongs to the aromatase inhibitor

family and by its very nature its primary mode of action is just inhibiting aromatase.

4). Letrozole directly affects estrogen by blocking the aromatase enzyme or better yet by blocking or inhibiting the aromatase process.

5). By its nature Letrozole greatly reduces the amount of estrogen in the body and prohibits estrogen

from conversion as is a common occurrence with many anabolic androgenic steroids.

6). By supplementing with Letrozole while on cycle we can prevent side-effects from occurring or at

least greatly aid in the process.
