Excellent perspective.... did you drink the protein powder all the way up to your show? Did you have to work your way up to that amount? Just didn't like cooking/eating?
when I was younger, (1990-1991) I used only foods, as I was pretty stingy and protein powders weren't really developed yet. other than cassienate and albumin.
I never competed again until 1995, and by then I owned my gym, protiens had exploded on the market, and I was totally sick of cooking.
actually, my last couple competitions, I pretty much had protein powders non stop all day, and then would eat a couple litres (quarts) of ice cream at night. I force fed myself for decades, and now really don't enjoy eating whole foods any more. not that I recommend eating nothing but protein powder, it was done out of laziness, (take that piana!! lol) and it seemed to work ok.
