It is a little known fact – perhaps, completely overlooked – but did you know that Polyprenyl Immunostimulant™ is a 100% made here, in the USA?

PI BottlesPolyprenyl Immunostimulant™, also known as PI or PPI, is a veterinary biologic, and a unique one too: it does not have analogs or similars worldwide. Veterinary biologics are products derived from living organisms and biological processes. They are used to prevent or treat animal diseases and function through an immunological process. Polyprenyl Immunostimulant™ is USDA approved as a therapeutic for signs associated with feline rhinotracheitis, a disease caused by herpesvirus. It is also used in experimental applications for cats suffering from Feline Infectious Peritonitis (FIP) as published by Dr. Alfred Legendre

But where does the ingredient in Polyprenyl Immunostimulant™ come from? The plants, our starting raw material, are grown and harvested in Tennessee. We select the crop and harvest ourselves to ensure only the best quality material ends up in our product. The process of transforming raw materials into a biological product calls for the use of several chemical reagents also manufactured in Tennessee or neighboring Kentucky.

We are proud to say that we do not rely on foreign-sourced components; we have complete control over every step of the raw material sourcing and manufacturing process, and we confidently stand behind our product. The health and the safety of your cat are all-important to us, you cannot have one without the other, and that’s one of the reasons why we are proud to say we offer an all-American product.
