lol, you don't have to eat steak when bulking..but it sure is nice!.. buy like 20lbs of regular ground beef at the store and eat until ur heart stops (shouldn't take to long)
as far as cost, it can be cheaper if you want it to be..
go to a bulk store and buy your oats in bulk, your chicken in bulk (and other lean meats)
no variety, but it gets the job done
