PCP Not Pleased With TRT

Just had my first checkup with my PCP since starting TRT in October. He was not happy with my choice and sees TRT clinics as a sham and said "they got ya". He is of the opinion that my lifestyle caused my low testosterone (he's not wrong) and I should have raised it naturally. He compared it to cocaine saying of course you'll feel great when you take it. I'm of the opinion that it's given me the shot (pun intended) that I needed to get my ass in gear. I feel the best I have in a long time. At the gym all the time. Eating a good diet. I've lost 30 lbs. Libido is back. No longer have severe depression.

He is concerned I won't be able to come off it and create my own T again. Is this true? What are your experiences?

Levels were 190 when I started and am 990 now.

Update: just want to thank y'all for your support. I was feeling pretty isolated after that moment. I'll be dropping this doctor and finding one that supports my journey. I appreciate each and every one of you...and the wealth of information in the group.
