With that said you'd think aromasin would be stronger... Wrong A-dex is stronger and letro even stronger! A-dex can lower E2 by 70% after a single dose, and Letro is stronger than that w/a % in the 90's for a single dose... If I'm not mistaken!
IMO - A-dex suites my body very well! However aromasin is usually underdosed(by the person taking it - it's advised to take 25mg Ed but being that people differ from eachother done can start w/12.5mg and adjust(which is what I would suggest to someone newer)!
Hope this can shed some light for some regarding AIs!
