When I found this Forum and learned about the importance of FT3 and found mine to be in the lower third of the range, I persuaded my doctor to switch me to Armour. That was working great until
Armour was no longer available. I switched to Synthroid and
Cytomel and after some dosage adjustments, I am now on 150 Synthroid and 12.5 mcg of Cytomel, with the Cytomel split into two doses, in a.m. and late afternoon.
