I agree with CC, arimidex only if you are prone to gyno which you don't know yet. I'm gyno prone and the advice I'm gonna give you is AS SOON AS you start feeling you nipples are sensitive or hurt a bit start taking the arimidex and don't stop till the end of the cycle where the nolva can take over.

My first cycle was exactly like that, you are gonna feel like a beast bro,good luck.
