I've had the same spray for over 3 years.
It doesn't have an expiration date.
I was wondering if it's still good or if I have to buy a new one.
I have no one to test it out on either... don't want to put anyone through that torture if it does work.

All aerosol pepper spray products do expire but the active main ingredient and inflammatory agent known as oleoresin capsicum (OC) is not what expires. In fact, OC itself can stay potent past the expiration date for a relatively long period of time if stored and packaged properly.
To put it straight, the reason why essentially all pepper spray canisters are stamped with an expiration date is because over time the pressurized aerosol canister will not spray the advertised distance, or at all.
Generally pepper spray products will carry a shelf life of 2-4 years from the day they are manufactured. Even though a pepper spray can potentially last you up to 5 years it is certainly advised you buy a new can every 9-12 months for optimum performance. Besides, the manufacturer cannot be held liable for expired pepper spray.1

Well my health psychology class discussed that regular mace isn't as effective as this other brand called "bear mace". I'm not sure if that's the right brand. Look it up, I assure you that one will never expire. But then again everything has an expiration date.. I don't know if this helps.0
