I think that soy is the fastest typical protein supplement after whey. I might be wrong about that. If I were you, I would just add some fats to my whey. It will have a similar effect. I like to do whey + peanut butter before bed if I need extra protein. You could add some olive oil to your shake. Or tuna + mayo (the kind with olive oil). Just my 10 cents.
