6lb of NitroCore 24 (56 servings) is $41 shipped. 200cal/5fat/14carb/24protein 4lb of Casein (also 56 servings) is $38 shipped. 120cal/1fat/4carb/24protein I have whey protein isolate for PWO...I need something for other times of the day e.g. in the morning for breakfast or later at night. Is the much broader blend of proteins in the NitroCore better than straight Casein?
