How long can a protein shake sit for?

I go back to work tomorrow :( (boo) I was wondering how long a protein shake would sit for. If I make one in the morning in my blender bottle. I would drink some on my way to work and most likely put in the fridge at work for a few hours. Would it be all foamy, clumpy or gross after a few hours of sitting or should it be good? Thanks!

I think it depends on the protein powder you use. I've used different
protein powders with different results.  Some are more clumpy than
others.  If I were you, I'd try it today before you go back to work. See if
your shake will sit okay in the fridge. If not, make a small one and
mix them as needed at work.

Thanks! That makes so much sense and is so much simpler! Why didn't I just think of that..LOL :-)

I use unjury or nectar. I make 16 oz shakes and put in the fridge to pour 3-4 oz at a time. Some times it has been the next day before I finished it. Just shake it good each time and keep refrigerated.

Cool! Thanks, I use nectar too.

I get the ready to drink for work, they are easier for me.  I like the EAS carb control chocolate fudge.  Good luck on going back to work tomorrow :)
