    I'm sure this question has been asked before:

    Suppose I let a weight gainer that has been mixed with water/milk sit in the fridge until I need to drink it (IE I accidentally made too much and would rather save it). Any negatives I should know about? A time-frame with which I should drink it?

    There really should be no problem with having it mixed already and sitting in solution. Would highly recommend not letting it stay in the fridge for more than 2-3 days considering the high protein and carbohydrate concentration of the shake for safety. There may be other supplements in the shake like creatine or an innumerable amount of vitamins and minerals but those should not be of concern regarding length of time in solution.

    Can't say the same for other supplements, but this guy's thesis suggests that mixing acidic OR alkaline drinks with creatine actually might make it convert to creatinine less quickly because of higher activation energy for forming the intermediate:

    So I usually mix mine with a little lemonade (pH=3-4). In any case the time frame is on the order of hours and days, 24-48 hours in the fridge should not really matter.

    Sugars and protein are usually fairly stable unless you got bacteria which loves that stuff. If you mix too much, try to drink what you need from a different container and refrigerate the rest.
