This is interesting. I just finished my first try with deca af 280 and about 7 weeks in I got bad bad moodiness and paranoia like to the extreme. I thought it was from increasing my test from 500 to 650. But maybe it was just the deca adding up. It more of less went away when I increased arimidex from .5ED to 1mg ED. Maybe it was the deca... it's amazing my relationship survived, I was all over the place emotionally.
