Need help with protein mixture from the factory

[busdriver1]

I need a good protein shake for after my postworkout insulin shot. i need 0 fat grams and 0 carbs as i am adding my own dextrose. I know whey is fast absorbing, but what about egg white protein. Egg white protein has 0 fat grams and whey has like 1. I know thats not alot but i would like to keep fat 0 or close as possible for the 4 hours that insulin is doing its thing. Is egg white a good protein for my needs after the insulin. If not, advise me a good combo.
