Middle school-high school horror thriller genre

A boy that gets into a lot of trouble gets caught breaking and entering and gets put into a juvenile detention that does genetical experiments that turn the children's body into huge muscled monsters that are unrecognizable and it is known to be un-escapable but the boy trys with a few others. But that's as far as I got and can't remember the name I really want to get it again and no its not from Steven King.
