ProStak® Expansion Pak

Great item to use for traveling

I received a Blender Bottle for Christmas that had the two separate containers on the bottom. I had been searching where I could get another one and then finally saw their ad online. Love them as I can carry my meds in the cup. All-In-One

Love the ProStak

The blender bottle and ProStak really work together to help me fulfill my nutritional goals throughout my days when I am on the go and my car is my temporary office. It makes segregating portions and differing supplements/protein powders convenient and easy.
