How to mix PB2 in premier drink w/o blender?

I'm going to try to add some PB2 to my chocolate drink to cut some of the sweetness, I don't have a bullet or a mixer bottle, if I shake it will it dissolve eventually? or do you mix it with water first then add it?

No idea, sorry.. I haven't ever used pb2. I don't know how well it mixes into anything.

I just threw some PB2 in with my chocolate protein,  shook it up, and drank it down. It was delicious. No chunks. A good shake should work for you too!!

I don't have a blender and I use PB2 every day!  One do those little metal ball thingies will help, but ice cubes work in a pinch. 

I just use a plastic jar, add Unsweetened Almond Milk, protein poweder(s) and shake well.  I mix it with a spoon, then I add 3-4 ice cubes.  Stirring it before adding the ice cubes prevents clumping, and the ice cubes thicken the shake up a bit, but prevents the "frothiness" that I didn't like.
