Aromasin over adex for sure. Adex merely occupies the aromatase enzyme, aromasin destroys it, that's why it's known as a suicide inhibitor. Your body has to then produce more aromatase enzyme before it can even start to work again. I like aromasin at 12.5mg/ed on moderate cycles, 750/week of test or less... When I was on 750/week of test enth and up to 80mg/day of dbol my 4th week I was using 25mg/day of aromasin, stayed totally bone dry. Of course, I was also using proviron at 100mg/day too lol, I'd have to take like 2g's of test to overcome that much anti-e. Oh, and aromasin doesn't have the negative lipid effects that adex and femara can, and it doesn't hinder my sex drive at all.
