He is in really good condition, it hurts a lot to get to that condition.
I don't see why he couldn't bench 450? Everyone has different strength levels, when i was younger i did some big lifts on deads and squats which i would never post here because i'd be called a liar but i look better now and don't try and lift those weights anymore. Some people are stronger than others.
There are some impressive natural physiques out there, gh15 is always bang on the money but when it comes to someone being natural he can't believe it and they have to be using because he sells to everyone so everyone must be using. I have seen guys i know are clean and he would say they are on all kinds of stuff, so his opinion on this guy is going to be he is juicing whether he is or not.
