Any ideas to slow down the digestion of whey? That would be a great pre-bed snack if the digestion rate could be slowed down. Casein is not available in China, and the customs are such a pain in the ass to deal with, especially supplements.
If you want to slow it down, eating a whole-food protein source (like a steak) would digest slower. Add some fiber (salad) and fat to help even more.
Do a search before you start a thread next time.
