comparing arimidex, femara, aromasin regarding igf-1 and hpta levels

"It actually renders estrogen receptors useless."

no, it makes the aromatase enzymes it binds to useless. your body is constantly producing aromatase enzyme, so this is not actually a "permanent" effect.

Well said, I appologize bro...I edited my post before you replied because I only wanted to point out the info about IGF-1 levels...

well, this is all mental masturbation anyway I've used letrozole, and might be using aromasin soon. Then I guess I can give an educated answer to the difference.
