I was wondering if making a shake and then putting it in the fridge for another day will make the shake go bad. I am using Cytogainer if that helps.

I don't know about the nutrients aspect, but from my experience the shake tastes totally different after being refridgerated for only a couple hours, much less a day or more.

I tried it with Myoplex once. Drank 1/2 a shake, worked out about 30 minutes later, drank the 2nd half after the workout, and it tasted really different. Thicker too, too thick to put down actually.

I always use mine over two days, sometimes as much as 3. It does become very thick, but personally I think the taste betters after a few hours of refrigeration. Unsure about the nutritional aspect to it, though.
