Thank you for the response I am going to change my doctor I have to go out of network on my plan because I only have 1 endo on it. Did you notice any side effects from the armour? and yes levoxyl is only t4. I read Mary Shomans web page and she has a lot of info on normal numbers that are not so normal and I printed the article that was from a doctor and wanted the present endo doctor I have now to read it and it was like I was questioning his expertise! THanks again jamv
