I'm a fan of Stop The Thyroid Madness group and own the book. It's a good book to own and learn. They advocate very low TSH and upper end of range for T3 and T4. Mine are pretty much there and I'm on 120mg Armour which I finally got on in 2002. After a 10 year struggle with that "normal" mantra from docs.

I take Selenium daily and Iodine as well. I had highter TPO years ago and have not had that test for a good long while.
