I like Optimum's 5 pound whey. It comes w/ 4 kinds of Whey and it's perfect for after a work out. After a work out i don't think you really want egg or cassein, if what you're looking for is an insulin spike. I take 80g dextrose w/ 50g of optimum's whey. Fats, solid food, and slower digesting proteins like cassein and egg may interfere w/ your insulin spike. This is a great time to shuttle all the nutrients into your muscle, so take advantage of it.
