I've seen that kid on a TV documentary.. he is 9 or 10 years old.. can squate more than 2x his body weight, curl his body weight bench press MORE than 2x his body weight.. etc. He's training as a martial artist as well, if u think his body is RIPPED you should see him spar.. his punch looks like he could knock out a 20 year old and he's SUPER fast... i'm talkin REAL REAL REAL fast... BRUCE LEE REBORN!
On the interview the kid stated he has never ever eaten meat in his whole life. He says" why eat animal, I love animals". He gets all his proteins from eating nuts and drinking shakes.
sure looks like hormonal influence...most probably exogenous or maybe endogenous from a silent tumor producing hormones ...hard to believe its genetic..and he need to see an odontist
