Letrozole (Femara)

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

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.

Even as Letrozole was designed as a breast cancer treating medication, as is very common other uses have been found, most notably in the world of performance enhancement and among many Hormone Replacement Therapy (HRT) patients.

The Letro AI is so popular among so many performance enhancers it may very well indeed be the most common place one would find the medication and for most it will be performance enhancing related questions and concerns that they have with a desire to fulfill.

Very similar to the AI Exemestane (Aromasin) and even more so, to a much larger degree Anastrozole (Arimidex) of these three commonly used AI Letrozole is undoubtedly and without question the most powerfully potent of all.
