I have seen about reagents going bad after time on here, and my CYA agent came with my original kit in September 2016. Does it go bad? It has no expiration date on it. It has been stored inside in a controlled dark environment. Thanks!!

I seem to recall that CYA reagent seems to be the longest lived animal in the herd. I don't even know if it can go bad?
I'll defer that to Dave or Becky.
