This kid Juicing....no.
I would say no. He doesn't look like he would be juicing or have that appearance,... yet anyway. Some guys/kids can get pretty big alone. Having good genes, work out hard on a shedule, every day there.... you can get like that at his age/young age. In fact, I looked similar to that when I was 16, ...and same thing...everyone thought I juiced back then. When in fact, I did not start until my early 20's. He keeps it up, and does a couple cycles when he's older,... he'll do fine.
