Description

Letrozole  is the most powerful aromatase inhibitor going. It will practically shut your body down from producing estrogen. This is mostly used as a pre-contest drug for bodybuilders wanting to eliminate any estrogen related bloating. This drug will eliminate 98% or more of estrogen production in your body. As an aromatase inhibitor it is king!

As an aromatase inhibitor, Letro’s mechanism of action blocking conversion of aromatizable steroids to estrogen is in contrast to the mechanism of action of anti-estrogens such as Clomid, or Novadex which block estrogen receptors in some tissues, and activate estrogen receptors in others.
