fT3 mid-range would be 4.15, 3.13 is low compared to that.
Along with labs; your waking and mid-afternoon body temperatures are important.
I don't know what T levels one should have from whatever one Sachet is. As you are probably aware, I always look for transdermal T absorption issues with thyroid issues.
No need to test LH/FSH again.
Temps previous to TRT were 35.5'C average but Havnt checked since starting testogel. Other thyroid numbers below
TSH - 3.80
FT4 17.20 pmol/L
Hopefully this will improve on TRt, started supplementing kelp already have a multi with iodine but have got stronger iodine drops I could try
