To make sure I understand correctly. You just keep it on hand until u start having symptoms, and then u start 12.5 e3d and adjust from there? Once your e2 is under control do you stop the ai or do you run through the rest of the cycle?Go with aromasin. First cycle my ankles were so swollen I had to go to the ER. I my opinion 12.5 E3D is were its at.
