You are taking an anabolic androgenic steroid. Of course it will help you have muscles and be in "better" shape that when you weren't taking it. Same with the GLP1 drug and weight. You are literally taking drugs to lower your weight and drugs improve your muscle mass. I'm glad you are happy with the way you look now, but setting the bar to "must take drugs to make your body look a specific way that most bodies do not / have not at 45+" is literally part of the problem (or transhumanist). But calling it a choice everyone can make (hundreds of dollars per month plus all the doctors / etc plus all the gym time) is a bit far fetched.
