I love ketochow but the cream is a bit of a bothersome aspect. I have some at work for breakfast and don't want to worry about lunch but only have one shaker. A portable way to take multiple portions w/o refrigeration would be nice.

Do you have access to a fridge at work? If yes, you can store your pre-mixed KC there easily.

If not, popular options around here are either A) Use a vacuum insulated bottle which keeps things cold for long periods of time (search for "hydroflask" on Amazon or a cheaper brand) or B) Keep a cooler bag with ice packs under your desk.

I have tried both A) and B) and I do B) as I feel it works even better and keeps my KC ice cold all day. I simply store my cooler bag with ice packs in my work freezer, so I don't have to bring it to/from home every day. On my walk to my desk in the morning, I simply pull it out of the freezer, put my KC bottle in, and good to go.

but only have one shaker.

Simple solution: Either A) Buy a second bottle on Amazon or B) Mix 2 Keto Chow meals in 1 container (may need less water). I use this bottle -- link . Every day I blend 2 servings of Keto Chow (roughly ~1000 calories) and put it into this 0.75 L bottle. Both meals fit easily and perfectly. Note I don't use the straw; I just use a "classic" flat lid.
