QF doesn't put expiration dates on their products, it has a manufactured date on it instead. It is written in code that I'm not sure of what translates to what right now. It's like they use letters for the month and then the 2 year code or something, don't quote me on that.

Either:
You can wait till Killerweed or Burnt Toast answer because they know how to translate.
Call them for the key to unlock the mystery.
Test it with validity strips.

It should be good for 18 months after the born on date if kept out of the sun. Sun is its main enemy.
