Letrobol

Bentex Letrobol is a reversible aromatase inhibitor noted as the most potent nonsteroidal AI. It is one of the three most commonly used aromatase inhibitors by steroid users to control side effects related to estrogen as a result of the use of aromatizing steroids (the other two common AIs being Arimidex – nonsteroidal and Aromasin – steroidal).

Letrozole is a non-steroidal aromatase inhibitor (AI). Femara is the most well-known brand name under which Letrozole is sold worldwide. Out of all the AIs, this would have to be the least used among steroid-using bodybuilders to control estrogenic side effects. It’s an AI with a reputation for being unpleasant to use for us guys – and for some good reasons.
