The regular product in the jar works and eliminate my pain every where I apply it. However as time goes by my body adjust to it and I have to use the clinical strength. I guess I am different. Now I need a stronger concentration. Because my body adjust to the effects of the clinical strength. The clinical strength still works but not as before. As I said my body seems to adjust to it. I gave ajar to my brother in law and he said it really works and eliminate his arthritis pain.
