Have you seen the size of the scoop of protein? It's one big hefty scoop usually equals about 25g protein. Most of those pills take 1g of protein at most. Do you really want to take 25-50pills of that? Assuming you want a post workout shake, you're looking at over 50pills w/ dextrose.
Very bad idea IMO. You're better off buying a powder that tastes good and spending a little extra cash for better taste. Me, I'm a cheap ass, and i know back in the days what they drank tasted like peuk, so i'm not complaining.
