"Da Bomb: Beyond Insanity" hot sauce (Oxford OX4)

unopened. I can't see any dates on the bottle but it's at least 5 years old. does something like this even go off?

I can't handle spice like I used to and I heard that this sauce is not only excruciatingly hot but that it tastes bad as well. but maybe you're a masochist or want to use it to keep slugs away or something? :^)
