After two weeks on Serrapeptase, at 120,000 units per day, I found my knee stiffening up more...I had nice results into the first week and stayed with it, then realized it was doing worse for my knee. Mentioned this on another health group I'm on and another member said she had the same results. So I'm off Serrapeptase. Still work with Natto to continue to reduce Fibrogin, so thought I'd mention this.

DejaVu, wonder what your PT friend would say about my results.
