I have been using synflex for the past three months to help ease the pain of my osteoarthritis in my spine. For me it was a miracle. I was using a pill form of glucosamine prior to trying Synflex and only felt a minor change. I kid you not, within 1 week of taking the liquid form I was almost pain free. It's not the best tasting medicine, but well worth it. I was also suprised that it really doesnt cost any more than the stuff you can buy in the stores. Plus you have the convience of having it delievered to your door. I have told everyone I know about it, including my doctor. I hope you give it a try, and I hope it works as well for you.
