Hey guestion: Once you mix up the protein powder, how long is it good for? Here is why I am asking: I work 8:30am-4:30pm. I drink two shakes a day, one at 10am and the other at 3pm. Since carrying a blender around in my car and at the office (mental health, blender not a good idea with metal sharp points) so I mix up my shakes around 7am. They taste ok but seem to be thicker and after taste stronger. Does protein powder go bad after being mixed? I mix with 4 cups water, 4 scoops Beverly Internation Muscle Provider, 2 tablespoons natty pb, and 4 egg whites.
