Sups. Amino acids and greens mixes. Exp dates?

So, I was thinking about using my old supplements which were all open. They don't expire until 11/16 so should it be OK? I tasted them and they're fine.

And secondly how much should one worry about amino acids if you're trying to get into some moderate cardio? I used to do elliptical for an hour and burned about 500+ cals and I thought maybe my amino drink was helping me out. I'm sure it doesn't really matter in the end, but I just wanted opinions

At least greens mixes are good yeah?
