underactive thyroid
"Was taking Armour Thyroid 90mg, and the pharmacy switched me to this NP thyroid as a generic and it was awful experience, was like I wasn't taking anything at all, like they just gave me a placebo or something.  Not sure why such a dramatic difference, but this was just my experience, now at the pharmacy you have to specify brand name only by your doctor to make sure you get the Armour Thyroid, pre warning, unless it works for you then awesome."
