Doctors are just like any other profession - there are good ones and there are bad ones. Not all Doctors are idiots with respect to TRT. Some certainly are, but others are not. A patient certainly needs to be educated and advocate for themselves, but this is true of any medical field, and indeed any situation. If you just do what you are told, you are an idiot.
My GP tested my T-Levels over a year ago and since I was 302 he pronounced me within the normal range, in spite of the fact that my cognitive function was diminishing, I was depressed, had diminished libido, etc..., all classic symptoms of Low T.
I went to a clinic a few weeks later and was tested in the afternoon and my T was 170 and I started TRT that day. My GP was ignorant of the fact that symptoms outweigh the T level, that 302 in the morning was a peak, that my life was miserable. That doesn't make him a bad GP, just a bad source for TRT information.
I think part of the problem is you have many different specialists dabbling in the TRT field, Urologists, Endocrinologists, and others. My brother in law gets TRT from a Plastic Surgeon for god's sake, before that, it was his cardiologist, and they're jacking him up at 200mg of Test per week with no blood tests. Crazy shit.
So, you have to be informed.
