Is it possible to extend the shelf life of EPO extracts? If Customer needs to extend the shelf life, it is possible to proceed as follows: Customer sends a sample of the batch stored in its warehouse to EPO Quality Control Laboratory; EPO QC performs all the tests again and sends back the report to the Customer; Customer decides how to change the shelf life (preferably not be more than a year). To learn more about shelf life information and expiry date, please see F.A.Q 9.1.
