    On his recent podcast (1/24), Joe Tippens advised viewers to stick with Fenben made by Merck (SafeGuard or Pancur-C), because it was impossible to trust other sources of the product and most were being manufactured in China or Eastern Europe. I had just bought a bottle of Fenben capsules from the FenBen lab, (which I see are made in Lithuania), and I was surprised and disappointed by what Joe said. Pancur-C now costs $17 for 3 packets, each containing 222 mg. so that comes out to $170/month just for the FedBen part of the protocol. Based on your testing, do you believe that the FenBen Labs product is of equal quality to the Merck products and can be safely substituted?

      Greetings, Judith, thanks you for a question.
      While we hold Joe Tippens’ viewpoint in high regard, the European market is even more heavily regulated than the American market. The food and drug administration in Europe establish a high standard for European companies that distribute and sell their products for human use.
