Thread: Aromasin vs Arimidex

I am going to run a 12 week Test Cyp cycle 500mg/wk (split into 2 doses) and plan on using 12.5 mg of Aromasin EOD for AI (and along with my PCT) I have read alloy about both but is there anything that I am missing that running Aromasin (a suicidal) would be a bad idea? Thanks for any input
