Pingable, we have always maintained a 1-2 year shelf life for our products as well as most other products we sell. The Polycharged products are no different. They will "separate" rather quickly, but a good shake will put things back together. I have polycharged products that are almost 2 yrs. old, stored in my garage, (which is hotter than 72 degrees) that still work flawlessly. We have received very few issues with the polycharged products in the almost two years we have sold them. Often the issue is when people use the product without shaking them up before they use them. Even when I have taken a bottle of product out of stock that has been sitting for a while and purposely use it without shaking, it reacts a bit weird, but never anything I could not remedy by shaking and re-applying. I hope this answers your question, if not let know or give me a call.
