would it be benificial to use arimidex say the last 4 week of contest prep to help harden up? i wont be on any aromatizing gear, so im wondering if it will make a difference or just be a waste. i will be on 800mg eq, 100mg winnny/day, oral masteron, 75mg tren/day, anavar, and the last 2 weeks halo. what do you guys think?
