Lol I tried various T3/T4 combinations. Compounding, separate T3, T4., NDT. I use an approach where you use temperature charts, blood pressure, pulse rate to check Thyroid health together with labs. Various people have protocols giving such information.
Oh ok, I guess then I can't offer much help but to encourage you to keep experimenting and tracking temperatures.
Also perhaps you could try some of the herbs that Dr Wilson talks about in the video I posted above if you haven't already.
Wish you all the best in your future experiments!
