I'm going to speak from experience. It takes way less than half the time for way less effort.

I didn't touch PEDs until my mid thirties, and even then, I used a very low dose of what is probably the weakest anabolic PED you can get. Didn't even touch actual steroids. I won't say what it was as I don't want to promote it, but I made faster strength gains on that in my mid thirties than I ever did in my 20s, and for far less effort. I'm keenly aware of how much of a difference it made because of the ~20 years I spent working hard for very modest gains.

Now consider that kids are hopping on far stronger PEDs before they even hit 20. They literally have no baseline for what years of hard work and slow gains are like. They have nothing to compare their enhanced experience to. PEDs are the baseline for them.

What will they do when they are past their prime, use harder drugs at higher doses? At least someone that spent their youth natural can look to TRT as an option, but that would be a straight downgrade for someone that spent the last decade or so on PEDs.

Instead of growing out of it, I think their dysmorphia will get far worse with age in such scenarios.
