Hi, My name is Joe and I once weighed over 300 pounds. Every time I tried to get some exercise to lose weight, my back would go out and I could hardly get around. When I started taking just 2 Stem Enhance a day, my back stopped going out. I started going to the gym and lost over 60 pounds. I traded my cane in for a motorcycle. After about six months I stopped taking it. Six weeks later, my back went out. On the second or third day, when I could hardly get out of bed, I decided to start taking Stem Enhance again. Every couple of hours I would take one or two Stem Enhance and one or two vitamin C tables. By the end of that day I was find, and a few days later I was ready to ride again. This stuff is great!
