adex 0.5mg/eod , or aromasin 12.5mg/eod , i don't need that much i can run 500mg test/w without running any AI just use it at the end for a couple of weeks to clean the extra estro, it's just when i do 750-1000mg or when adding deca to the mix or any other aromatizable steroid when i include it from the beginning or at week 2-3. when i'm cruising on hrt i sometimes do Aromasin 12.5mg twice a week for maintenance like 8 weeks on and stop it for a while for about 4 weeks.
