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.
