I have had an open can of gatoraid powder for years. Drink some every now and again and it's just fine. Still refreshing as it was when it was new.
Had one in my ruck from my last tour at Ground Zero and it was still good.
Guessing if there's no holes in it and stored in a dry place it'll keep indefinitely.
FHUGETABOUDIT!!!

That stuff can turn into rock. So it really depends on the ambient conditions the sports drinks were tested in to really tell if the results are valid for this area of the world or not.
If you are taking synthetic antibiotics past their expiration date, you are pushing your luck. Lactic acidosis is no joke.
Mom's comin' 'round to put it back the way it ought to be.
Anyone that thinks war is good is ignorant. Anyone that thinks war isn't needed is stupid.
