Lifespan of PMK

I know the Book of Pyro says 'years and years' but I've got some PMK I mixed about two years ago and it's sitting in the nice brown bottles from Photo Formulary. It's been sitting above the sink in my darkroom through two winters and now two summers.

Do you all think this stuff is still alive? I'm planning on using it with Tri-X for a series of family portraits and I'd rather just start with a fresh batch than test my nights away.

thanks
