I just switch from masin to BLR's Formeron. So far so good, but it's only been 3 days. It has definately started to take care of my water retention and releived a little sensitivity from a little gyno flare.
The formeron also converts into a PH once absorbed, which is kind of cool.. plus it's 120ml and most guys get by on 1-2 pumps a day.. some less. And it's priced cheaper than 30 days worth of most Exemstane I come across.
Adex is stronger for me too, it can really make my joints hurt. I need to run aromasin at 12.5-25 mg/day on cycle, and 25 mg every 12 hours if running dbol. It gets expensive, so I've been trying to use adex on cycle and aromasin in pct.
