Well, I would expect T3 to go away when you have the total gland removed. The thyroid makes it. And it does not get much into the blood when you convert it in the tissues.

From what I learned, it is formed right where it is needed only.

I have read that taking your pulse regularly with T3, and also your morning temperature may help reveal if your dose is too low or too high. Increased heart rate is one sign of too much.

Only special compounding pharmacies do this ...and maybe not even many of them, either. You have to find those either online, or call around locally.

This particular topic appears on the net. I'll send you a link to it, in PM.
