"Should I increase the Lugols or add SKKI? I FEEL great. "
One does NOT feel great if one are hypo T, no way!
The tests arent reliable I am afraid; a better way to find out may be the Barnes temperature test. This is easily done yourself.
I feel great when my temperature is slightly over 37 C; when hands and feet are warm to touch.
When I was hypo T I felt like crap, was cold most of the time, temperature around 36-36,5.
I would give this some time; you may try to pulse the dosage, but if you are anything like me, it took a year or two to cure my hypo Tness with the Iodine protocol.
