What is Letrozole
The strongest anti-estrogen compound. Use only on a heavy testosterone cycle. If your get high estrogen levels and Aromasin or Arimidex don't lower them, then it's better to use letrozole. Some individuals have a low reaction to Aromasin or Arimidex. Then it's possible to use letrozole to lower estrogen levels. Another advantage of letrozole on heavy testosterone cycles is that you can use fewer tablets of anti-estrogens. Be cautious, letrozole can suppress the majority of estrogen if not all.
