After having neck surgery I could not get up a move around much, due to the stiffness in my neck and upper back. My Husband bought home a bottle of the 420 X Pure Pain roll-on 5000mg and he massage my neck with it in a few days I really started to notice that my neck was feeling a lot better and I start to be much more mobile. I am back up and driving without much stiffness.
I recommend this product to anyone with joint pain.
