I inquired about Armour with my endocrinologist. He was willing to prescribe it, but I have issues with my Free T4 and Free T3 so I have to be on both Synthroid and Cytomel. I just had my second dose of RAI so I have to be regulated again - I was off meds for 5 weeks - the hypo hell was horrible. However, before I went off, I had added Cytomel for about 8 weeks - that addition, along with the Synthroid made all the difference for me. Know yourself, know how you are feeling and try several different combos to find out what is right for you and your body!
Hope this helps.
