You’ve been quacked, this doctor is a newbie at TRT and this is the new lowest prescribed TRT dose in human history.
This seems to be the way sick care operates, optimal doesn’t seem to compute. A month ago I told my doctor my diabetes is worsening and A1C was 6.6% and doctors refused treatment, now a month later A1C is 7.7%.
You have to hit this arbitrary number to get treatment. You have to be dying or seriously ill to get treatment these days. I would argue an A1C of 6.6% is room for improvement.
Healthcare is dead, welcome to sick care where doctors keep you in a diseased state.
