Hi Kathi. I didn't see your message to me earlier. I wish online forum software would alert us when someone replies to us. Thanks for writing to me. I'm taking Armour thyroid. The web site says it contains T3 and T4. I'm going to have a talk with my doctor about this, including telling him more about Teitlebaum. BTW, have you thought of contacting a personal injury attorney. You can simply talk to him. You don't have to pay for a consultation, and you can consult with more than one.
