I have read in numerous places that 1-Andro RX alone can not cause Gyno. Is this true? I am an endurance athlete and spend a lot of time running. I have sore nipples but I want to make sure that it's not from the 1-Andro. It could be from rubbing on my shirt while I run.
Thoughts?

Arimidex
-or-
Letrozole
While these are some of the best AAS related gyno prevention compounds, they are also very strong, not compounds to mess around with or take lightly. Make sure you do enough reserarch, regardless of what path you choose to prevent gyno.
