I usually buy the RTD (ready to drink) shakes that I enjoy very much. The main reason - they are convenient, no refrigeration needed, taste good at room temperature, fits unnoticeably in my bag and even in my pocket and I really like the chocolate flavor ones.
I also have a lot of the powder drinks since I buy everything in bulk and was wondering, if these shakes can be prepare a day or 2 ahead of time and refrigerate it? Will it thickens and the taste resembles a real milkshake or does it loses it flavor, thin out and lowers its nutritional value
