Anyone ever have any complications with this stuff? I’ve always ran it at 400mg a day with good results but this time around it seems to make my anxious, acid reflux from hell, pressure in my neck and headaches. Bloodwork is great except for my TSH, which is rather high for obvious reasons. I noticed neck and some chest discomfort after taking it for a little bit and honestly all this is a first for me. I love the stuff but maybe I just got a trash batch? Not sure.
