Well, I gave T3 my best shot for 3 years now...as the crow flies, recently added back in T4 (only 50mcgs per day, which is something I thought I would never, ever do!) for the last 5 weeks now and without making this a long post am thinking since I now have been diagnosed with the latest "side effect" of this disease...fibromyalgia...(!) it could not hurt me to try something I never tried before which is NDT/Amour. But where to get it? Anyone know where I can buy it on the internet? I am now age 60 and being sick with Hashi's for 20 years, enough really is enough! Anyone know a supplier? Thank you!
