Sounds like OP should have stuck with the first Doc as it seems he would have come around with weekly injections eventually. Many Docs are uninformed on TRT, but people on here have educated their Docs over time and build good relationships with them. If there's a lesson here, it's that one should never play Doctor themselves. If you had not increased the dose yourself, that second GP would have been on-board.

Believe it or not, most Docs "do" know more than us & are not automatically as*holes. They're professionals with a high degree of training and have a lot to lose if something goes wrong due to a non-compliant patient. We all should keep this in-mind...
