Since you brought up steroids, plenty of people take a gram of gear and look like they don't even lift. I'm not saying that someone taking anabolic steroids should act like they've worked just as hard as someone who is natural and at the same level of musculature, but good results take effort and consistency in the gym, diet, and rest of your lifestyle. You get some benefit just from being on steroids, but and there might be some genetic freak hyper-responders that blow up without any of that, but the overwhelming majority of people aren't going to look like they're a steroid user if they're not pushing themselves very hard as well, and the sheer amount of mediocre physiques from people on gear proves it.
Similarly, if someone turns their lifestyle around with the help of a GLP-1, if they change up their diet from crap to decent or good, if they move from being sedentary to exercising regularly, does the drug get 100% of the credit? Do we throw away all of the other work done?
You can both take a drug and also put in significant work that you can and should be proud of. Both things can be true.
Belgian Blues dont really need to go to the gym, so it’s not really that hard to phantom.
Belgian Blues grow that large because of a mutation with their myostatin gene. This is hardly the same method of action.
You're not going to accidentally an Arnold by injecting testosterone and sitting on the couch every day.
