he could be all natural... 6 years is a long time.. especially if you are very dedicated... i say this because.... when i was 15 my sisters friends said "does he work out?" even though i didnt touch a weight ever then.. when i started working out people said "he takes steroids" even though i didnt.. now that i take steroids..... people just say "wtf? hes gotta be on steroids no doubt about it"......genes are everything haters......btw nice work bro.
