I have some Cyper WP I bought a few years ago and its still about half full. What is the shelf life for the product- or is it still usable?
Cyper WP has a shelf life between 3-5 years. You want to keep stored in room tempature away from any moisture. Extreme tempatures can lessen the effectiveness.
