Just updating my previous post. I got a call back from the maker of the Zorex Chocolate Whey/Egg White Protein Powder, and there is no additional sweetener, which was so surprising to me because it tastes very sweet. He said it's just naturally occurring lactose, and the ingredients are Whey, Egg White, Cocoa Powder. That's it! He just left a message but I'm going to call back and find out where it is available to buy.
