Hi , I have been using 0.5 mgs of arimidex ed. Doing a test cycle of 500mgs per wk. I usally use nolva. First time using arimidex(prone to gyno). Is depression a side effect of arimidex? Also can having to low of a estrogen level cause depression? I have done 5 cycles in the past and never felt weird like this before . Could it be the arimidex?? Should I switch to 0.5 eod . Need your help on this one !!!! Anyone had depression from arimidex or to low of a estrogen level??? Thanks
