I think as long as its cold, it will be fine. I brought all ready mixed protein shakes to school. I put them in a lunch box, with a shaker cup that dosent leak with an ice pack worked great, other than the fact that every one asked me what I was drinking. The longer you let them sit, the mix better, get thicker, and taste better. So if there cold they should be fine to drink.
