There will be no expiration date listed on the Pyganic Pro, only a manufacturers release date that should be on the bottle itself. We are not sure exactly where on the bottle this would be as this product is no longer available. The product has a 3-5 year shelf life from the date of purchase if kepty out of extreme temperatures and direct sunlight. MGK who is the manufacturer can be reached at 800-645-6466 and they may be able to better help you find the release date.
