I usually get home from the gym at around 9pm and drink a whey protein shake that has 60 grams of protein. I wanted to start takin some casein before bed. Should I add it to my shake post workout or should I drink it at midnight before bed. Also what ratio of whey to casein should I take if I use it post workout and how much casein should I take if it is right before bed. Im 6', 185 lbs with about 14 percent bodyfat.
