Question about a suppliment?

I have a mass gainer suppliment but I do not have a blender. 4 scoops is one serving I tried just shaking it up it didn't turn out so good. It is mostly whey protein with other stuff in with it. What I want to know is in stead of taking 8 scoops(2 servings) would I be able to take 4 smaller servings of 2 scoops. Or should I wait to get a blender .will this be just as good as taking the 2 servings it says to take
