Letrozole is an aromatase inhibitor. It is used in breast cancer patients to keep estrogen levels lower. Bodybuilders use it for the same reason, as when they are artificially boosting testosterone levels, the body converts excess testosterone into estrogen. Letrozole inhibits the hormone that causes that conversion. Female bodybuilders, AFAIK (I’m no expert in the female side of things) would have no need of Letrozole.
The other drug which is also known as Cardarine is not something you would take an aromatase inhibitor with, as it does not affect testosterone or estrogen levels.
