My ratio 2 months ago was 21 on 75 mcg T4 only.
Since then I have tried going T3 only but I feel better with T4 in my system.
However since my ratio was 21 on such a tiny amount of T4 then on 200 mcg T4 and 18 T3 the ratio must have gone to an unhealthy level under 20. I was feeling more and more hypo on 200 T4.
I may be one of those people who should go T3 only and will always have a reverse T3 problem when on T4 but I cannot tolerate T3 alone.
Does this mean I am bound to be hypothyroid for life?
