Is it OK to prepare protein shakes the night before for breakfast?

8 hours??? What is there some Myoplex police that make this shit up? Why not 9 hours or 7 hours......there's no difference.....make it the night before, fridge it, and go......OR, better yet, tell her ass to get out of bed 2 minutes earlier....geezus......then we solve this problem and quit wasting time haggeling...

apparently myoplex loses its potency after 8hrs, not sure about other, it was on their website, dunnno if its true though

What potency ?

If you leave your cooked chicken breast or cottage cheese (which are also proyeins) in the fridge for 8 hours, will they lose their "potency" ?
