So I've been on 75mcg T4 and 30 mcg T3 for the past 2 months after being on 100mcg T4 and 20mcg T3 and here are my results:
TSH 2.7 mu/L (0.2-5.0)
FT4 8.4 pmol/L (9-24)
FT3 - Not measured (GP bloods)
Here are my previous results on 100mcg T4/20mcg T3
TSH: 2.62 mIU/L (Range: 0.27 - 4.2)
Free T3: 5 pmol/L (Range: 3.1 - 6.8)
Free Thyroxine: 12.500 pmol/L (Range: 12 - 22)
So I expected my FT4 to lower as I decreased my levo but really surprised to see my TSH still so high.
I know it's FT3 that matters but I assume if that were high in the range then my TSH would have lowered, which it's not, despite increasing my T3.
So basically I'm very confused, particularly since I actually feel pretty decent at the moment, which I attribute to my body preferring T3 to T4 (although this may be a product of B12 injections, but that's a separate issue, currently awaiting testing for Functional B12 deficiency)
Any advice regarding where I go from here ? Perhaps another T3 increase to 35mcg or even 40mcg ?
