Anyone else here use All the whey chocolate isolate? I bought 2lbs because i heard a lot of good things about them. According to the label its supposed to stir intantly but it doesnt for me? Its like theres clumps of sand heh? Anyone else have that problem? I dont like using a blender and im used to using Optimum nutrition where i can just use a fork to stir it up for 2 secs.
