lot of believable posts itt 
mesmorph natural, uncle junior doesnt train legs and can crank out 400 x 8 @ 170 lbs, etc.
anabol bringing the truth as usual
my best natural squat was 5x170kg (374lbs) at 85kg (187lbs)
i didnt get a chance to record this but i did record next weks workout of 3x170kg, wes saw the video
i find 8x400 unlikely as well but it depends on the ROM, mine was olympic squat so full leg flexion
since roids i dont squat anymore for the androgen receptors in the obliques would give me a rich piana like butterfly taper at the waist
instead i pump the leg press
