I use a combo of the two. Aromasin works much better for me when it come to controlling estrogen but it does nothing for water weight. Adex dries me out

IMO dood Aromasin is the much better AI....Let me tell you why...
My specific preference of aromasin is becuz just 25mg decreases aromatisation by 98% for a period of 5-7 days. In addition, it shows a very positive effect on LH & FSH, as well as increase in gonadrotopin, making it great not only on cycle but also for pct.
Furtheremore, it also increases IGF-1 levels, which is a much desired effect. Moreover, it is less harsh on blood lipids than other AIs.
These qualities make it much more superior To other AIs like "adex". And if i was taking it during a cycle to stop LARGE amounts of gear from aromatising it would be my only choice bro.;)

Funnily enough, ive read dosages In excess of 400mg/day of aromasin Have shown to act slightly androgenic, which is not relevant though as the price is quite high.

Dont listen to the "I used it and liked it so its better" crowd. Look at the science behind compounds and then choose whats best for you.

I always used adex but I'm just now getting into aromasin because it's easier on the rebound effect when you stop use
