Description

Letrogen, known as Letrozole (or Femara), is classified as an Aromatase Inhibitor (AI) drug that is therapeutically used to treat breast cancer, but in the performance enhancement scene it is an invaluable non-steroidal ancillary drug used to mitigate estrogenic related side effects from aromatizing steroids. An aromatase inhibitor is recommended to use for most steroid cycles to avoid the onset of estrogenic side effects. Letrogen is the strongest and most suppressive commonly used aromatase inhibitor.
