It looks as if it has worked!!!
For me it is 300kg raw in the gym, and 300kg equipped in a 3 lift comp.
This was at 105kg bodyweight.
Please state if your lift is raw or equipped, although DL suits do not give the sort of increase that bench and squat suits do.
My short term goal is 317.5kg which I believe is 700lb; longer term, I think I have 350kg in me. We shall see.
