i think he just had good genetics and worked out. i know youre going to argue the fact that he had nice size at the beginning then shrunk so much. im sure he just didnt work out as much or something while on the show. i know the area he is from and its SHIT and in the ghetto. and during the show he kept ragging on how it was only him and his mom and money was tight. i dont think he'd be blowing his supposedly limited cash supply on juice. but of course, never say never....
