Question is: how old's the guy on this video? Ih he's 20 and training for a couple of years then I really doubt that he could achieve this without juicing. Of course, he could be natural after let's say 4-5 years of smart training, no major injuries, very good genetics, good amount of sleep and perfect nutrition... help of god, nice even weather all the time, not catching a cold ever, having a girlfriend who doens't break his balls, etc....
