The OP of this thread(bigmc) is the biggest liar and Bullshitter in getbig. And he is a mod 
I've got no beef with MC, he's been cool with me, but 500 is a fantasy
I worked out with the Army powerlifting team champion, at 280lbs+ at 5'10" he barely would get 550+......after working with him for over a year he got me to 405x3 at 235lbs and I was 10% or so BF working out 2x daily, Army PT and then lifting with him.
Just for perspective this is me a year or so ago at 210-215lbs at 12-14% fat
