I think you’ve got a good chance of improving things by lowering dose. Coming off TRT is an option for you but might not be necessary. You also shouldn’t fear having to come off TRT if it comes to it. My experience really wasn’t that bad. Read my restart log if your interested. There’s a video link of a YouTuber who blasted and cruised for 8 years then successfully restarted his HPTA. He has compiled his dosages and lab work over 3 months of PCT so it’s a good resource.
