Pre-Bed Formula Ideas

I train 1-2 times per day depending on the day. My recovery is good, but not great. I do a lot of running, and my resistance training is mostly explosive movement exercises.

Would a pre-bed protein help with recovery and keep lean muscle? What would you suggest?

Would you add low GI carbs? I want to get lean. I need some fat, but am looking for 10-13%.

I was thinking:

45% IPI for the slow micellar and fast isolate (what type of whey isolate is the IP?)
25% Milk Protein Isolate
15% Aussie
10% WPC
5% Glut peptides

Should I add aminogen?

Thanks
