Great posts do what you said in the PM and I will respond. PharmaCyte Biotech Successfully Completes 1 Year Stability Study PharmaCyte’s Chief Executive Officer, Kenneth L. Waggoner , said of the completed twelve-month stability study, “We are pleased that our CypCaps™ product successfully completed all of the required stability tests and that the product has now shown itself to be stable and active after being stored for 1 year at -80oC. The study will continue in order to determine the maximum shelf life of the CypCaps™ product. It should be noted that this data is exceptional for a product of this kind.”
