Just though I would chime in here with my current Cissus experience.
I've had lower back problems and joint problems in my wrists and elbows for the past couple years. I've tried several products and they have helped a little bit but ever since taking the Cissus my problems have been MUCH less problematic. My lower back takes a beating because I love to golf as well. It usually take a good day or two to recover from a full day of swinging but its been MUCH faster taking the Cissus. My joint problems still flare up while working out but it doens't prvent me from doing any exercises (it did before sometimes) and the next day the pain is pretty much gone.
That is my experience and I will continue taking it.
