Still see no need to test estrone or worry about it.
E2=15 was on 0.7mg anastrozole per week?
E2=15 is considered low. AI dose should have been reduced, not increased.
Are you on TRT or AI only?
T4 1.12 / .82-1.77
TSH 2.32 / .450-4.5
IGF-1 121 / 88-246
T3 15.1 / 9.2-24.1
Triiodothryronine 3.3 / 2.0-4.4
GH status is getting low. [IGF-1]
TSH should be closer to 1.0
fT3=3.3 is strong mid-range and should be able to support good body temperatures, but I have suspicions.
Evaluate your overall thyroid function by checking oral body temperatures as per the thyroid basics sticky. Thyroid hormone fT3 is what gets the job done and it regulates mitochondrial activity, the source of ATP which is the universal currency of cellular energy. This is part of the body's temperature control loop. This can get messed up if you are iodine deficient. In many countries, you need to be using iodized salt. Other countries add iodine to dairy or bread.
