your a dumb Ass. there's many reasons but here's a few....
1 we Don.'t know his training routine
2we Don.'t know what his diet is like
3we Don.'t know how consistent And dedicated to this he is
4 we Don.'t what his previous stats were Or are now Or how much of his gains are muscle, waterweight,Or bf........any vet will agree with me, with the information given there's no way to give him an answer without shooting blindfolded And in the dark
