I'm not offended by the suggestion. It just doesn't make logical sense based on first person evidence. Those who change up their routines seem to (so far, at least) be having much longer and durable success. Taking the drugs absolutely allowed them (and myself) to do so, but it doesn't explain why others did not and the nearly perfect correlation between outcomes.
It could simply be luck I suppose? I'm not sure what other explanation could explain differing outcomes.
The thing is - I honestly don't care. If I return to old habits again and the drugs get me off those, great. I'll take it for life. It's not a moral issue to me, it's a practical one. When friends of friends come to me for advice, I will continue to tell them that it's most effective if you use it as a means to performance enhance your dieting and then use that space and motivation from the results to change your lifestyle habits that got you there to begin with. It's simply what seems to work at a pragmatic level.
Telling someone "don't worry, the drugs are going to change your grocery shopping decisions, get you walking on a daily basis, and get you into a consistent gym routine 100% on your own" seems rather silly. I can't see how it's helpful to anyone. It sets far more people up for success if they also put effort into change from their end as well.
Re: Steroids - those who work out while on them are going to see larger gains than those who don't. They are called performance enhancing drugs for a reason, same as I think of the GLP-1 drugs - just in a different category. You certainly will get results with either, but they increase the results of effort put in as well.
In the end, do what works for you! The health outcomes of these drugs are amazing, and I think they will be up there with the most important medications ever invented in terms of quality of life years saved.
