The tl;dr version is this: if you’re taking trt doses you will eventually hit your ceiling, which should be theoretically higher but within close proximity to what your ceiling would be naturally. If you’re using enough testosterone to be supraphysiological for any meaningful period of time then you’ll gain over and above that ceiling. But again, you’ll eventually run up against a dose-dependent limit. But what I just described can take a decade or more to play out. So use the minimum effective dosage for as long as possible.
