A member asked:
What do you do if your nitroglycerin is expired?

Throw it out: Don't ever use old nitro; it won't work and you'll end up going to the emergency room.

Buy more: Ntg is good for 6 months if kept in an air tight amber glass (light resistent) container. If it's opened, it's only good for 6 weeks. After that, it should be discarded and replaced with fresh ntg.
