made myself a protein shake the other nite for the morning after (to save time). however i later read that it should be comsumed within 20 mins. is that the same for all protein shakes or just this one in particular. and why does it have to comsumed so quickly afterwards?!
I made a protein shake once and although I knew the advice was to drink it straight away, I left it a couple of hours.
When I came back to it it was virtually solid, and undrinkable.
