Great stuff. I gave this to my dad for hip and knee problems and after 2 weeks, he had no symptoms. This has been an ongoing issue for years, so all I can say is that I am overly thrilled with the product. Personally I had tendinitis in both arms and couldn't lift 10 pounds. I'm a 34 year old fitness freak, so this bothered me. After a month of wobenzyme, it was cured. For maintained, I bought this, because it was half the price, and it worked just as good. Happy customer.
