He looked a world beater when he won the NOC, after that he went downhill, I think he needs to severe ties with Greg V, anybody assoc with him goes down, like he's a detriment to competitors.
I don't see obvious use of syn, but his arms have looks water in the past, but then, his whole body did as well. He as gained a lot of weight, so his arms will grow, but he is losing cuts and it shows in photos as well
