going to be my first cycle and i think ive gotten it pretty close to right but would like some advice to make it spot on

Week 1-12: Test E, 300/wk (I have been told to run 500 but my first cycle and others say 300 is plenty )
Week 1-12: Exemestane 25mg EOD (researched it and its 85% estrogen suppression so hopefully just as effective as arimidex or aromasin )

PCT - starts 2 weeks after last injection
Nolva: 40/20/20/20

I read up on clomid and seems to bring too many side effects, and the nolva is stronger so i was going to just run it alone

if ive got anything wrong ill gladly take advice
