Getting jacked in your 20s allows you to resize to a smaller (but still good) size which will be way easier to maintain for pretty much the rest of your life, with far less effort and sacrifice.
If you're natural you don't even necessarily get to that peak ever.
Plus, being jacked in your youth comes with so many advantages, social, psychological, etc. that will affect the rest of your life, and those advantages become less useful the more you age (pic related), so even with all the patience in the world it's in your interest to get as much muscle mass as possible, as early as possible.
You don't even need to get on so much stuff that your life is significantly shortened. Even just a moderate test dose will make a substantial difference with minimal side effects.
