my 480 was raw, belt only, best competition lift, 495 is my best 'gym pull' also raw...
i've had 500 above my knees a couple times now...
the world record @148 is 700 by jaroslaw olech ...look him up on you tube... THAT is a good pull...
im an energy drink fiend... i make my own mix:
1/2 redline
1/2 endorush
4tbsp liquid aminos
4 scoops waxy maize (50g)
and sometimes i take a bit of ephedra with it...
