What’s ‘young’ ?
And the reason that you don’t see it isn’t because it’s not possible; you don’t see it because you very rarely have someone 6’5” choosing to bodybuild. Its much harder to appear huge at that height, and most guys get into bodybuilding for cosmetic reasons.
6’5” 250 is definitely feasible without gear.
My lifting partner a few years ago was 24 and 6’5” 270 lbs at about 12-13% bf.
I know FOR SURE that he didn’t use gear.
Yeah 12-13% isn’t shredded, but with that physique and the correct diet, you would only lose about 20lbs peeling down...as long as you did it correctly.
You really need to drop the ego kid, because you’re straight up wrong, speaking in GROSS generalizations.
