What rT3 would you be shooting for? There is absolutely, positively nothing wrong with your thyroid blood work
There’s a reason Endos do this. I thought I was smarter than my body until I ran into issues.
Unless you go and biopsy your individual tissues and determine you have a deiodinase issue, better to let your body work as designed.
I worked my way up to 150 mcg/day of T4 and 50 mcg/day of T3 (split), scanned rT3 levels from 28 to 6. None of this changed my basal temperature upon waking. I did end up with AFIB. Tread lightly with the T3 and don’t get your thyroid care from a forum.
If you are going to start self-medicating with combo therapy, please God, start very low on the T3. You will end up chasing your tail listening to the internet BS on rT3, running serum T3 to top of range, etc. Total BS.
What do you think is going to happen to your fT4 when you start taking exogenous T3. You are shooting for a fT4 below range?
I’d listen to Saya if I was you. He is not conservative on the thyroid so when a “clueless” Endo and Saya both would tell you the same thing, I would listen. Take care and don’t fix what ain’t broke.
