Yeah, ya never know you COULD be the ONE person in 20,000 who develop's antibodies to the Armour. (sorry couldn't resist!).

Once YOUR TPO's go down and the thyroid is 'dead'..the Armour almost CAN'T raise antibody levels, been proven and like...oh my...50 years ago??? Holy moly! What are these doc's reading???

But, I know a LOT of patients who are well replaced on synthetic T4 and T3 and tolerate it well...you don't HAVE to be on natural thyroid to get T4 and T3.
