I decided to try with T3 as explained in my previous post. Nobody here was very helpful with giving me a source except one person who directed to to another forum where I got info I wanted right away. Anyway, T3 in now here but I am not sure how to start. I am on 100 mcg of Levo and T3 is Uni Pharma and tablets are 25 mcg. Do I take them whole or cut them in half? Also how much less of levo should I take? If anyone wants to help, thanks!
