i can tell you this... if you are at all gyno prone then adex is not the answer... i have seen so many fucking guys using adex that are gyno prone and it does not help... now, this may be due to the fact that the quality is not as good as others but its definitely not as strong as aromasin... aromasin is a suicide inhibitor while adex is only going to suppress estrogen... aromasin is stronger... i have not used adex myself because i have had great success with aromasin... forma is great in pct and aromasin will keep you dry as fuck... you need to be careful to not overdo it though... 12.5 mg eod is a good dose of it... you can go ed and see how it effects you but eod is standard for it... im not saying adex won't work but its definitely not as strong...
