You can do that but what you may find is that they thicken as well as settle. Most of the powders mix without a blender. Find one you like and get a shaker bottle. Put the powder in and just add water when you're ready for the shake. Works very well with the Optimum, ISS, Designer brands to name a few that I've used that way. If you're in a real hurry you may have to settle for a protein bar even, but try the shaker bottle first.
