We do see some docs who do not understand the fine details and will look at FT or TT and see one in range and say the normal word and not take action. Your doc does understand the importance of FT, but may not be considering how FT fluctuates. When on TRT, FT is steady, but will rise and fall with weekly injections. FT is very steady with injections EOD. E2D, E3.5D, so FT labs results then are a real good indication of overall status. But overall status really must consider FT and E2.
