After reading your note once more, I just want to add that if you do have a goiter, in my opinion rejuvedine is more apt to be a really good thing. I'd still get it muscle tested, to be sure.
I also wanted to let you know that I know a women who can do muscle testing for you, over the phone. Personally I always check it out myself, and then I ask for help from other people that muscle test for me. I don't want to make a mistake so to me its safe to check out supplements this way. If you're interested please email me.
