I am trying sustained release T3 now with
cytomel and I am not having luck with it, I prefer
cytomel alone (I used it before)-it works much more effectively for me. You might need some adrenal support like cortef to continue, and you should check your ferritin levels too. Mine are low, which was probably another reason why stuff wasn't working for me. Synthroid probably won't do it for you, if it hasn't already, just my opinion. Get some blood tests and try some cytomel if you can.
