Good question. I actually don't use protein powder or any mass gainers. I have a few protein bars/cookies that I keep for emergency in case I know I will not have access to protein. In my opinion I recommend you to eat real foods, meats, fish, eggs and lots of low fat yogurt. When I stopped taking supplements a few years ago and switched to just foods I noticed an improvement. If you still want to take protein supplements I recommend a whey isolate post workout or in the morning, and a casein protein before sleep. Equivalent of whey isolate are egg whites and chicken, equivalent of casein protein are dairy. Hope it helps :)

absolutely, thanks for the response
