As for syntholuse I can't reach any conclusion. Sometimes it seems he uses but if we pay attention to the las pic, his shoulders have striations. If we look to that 1991 pic we can see that he is the most genetically gifted bber of the present days, to build mass. People should also realize that is is very strong, this guy training olny for stregth would be a serious case (leaving the 16 reps sets and doin PL moves). He was born to do strength sports, I think he could reach the level of Mariusz.
