Yes. I assist patients and was called and asked what will help my girlfriend. She had been given less than month to live and I suggested Serrapeptase. Without question and really nothing to lose she started with 9 pills a day. I was shocked at first at the level but it turned out very beneficial. At 2 weeks she had her energy back and at 1 month the doctors gave her a clean bill of health. All the blockage was completely gone.
