Hi, you must insist that the endocrinologist run Free T3 when he does your bloodwork. Also insist that he adds cytomel to your prescription. Cytomel is T3, whic is the active hormone. It will take awhile to get them titrated, but I am on 0.2 levoxyl (T4) and 2x 25mg (AM/PM) cytomel T3. It took me 6 years and 150 pounds before I got the right doses!

Take care
