Hi all, I've been on Armour, 3 grains for about 6 months now (Rxed by my Doc). I wanted to try something different, something that didn't have the fillers. I have tried the Canadian ERFA thyroid, but it's expensive and takes too long to get here in the States. My doc is cool, and will let me try anything I want to. What NDT have you found to be the best, thanks!
