Review (4/5): It's ok
I was buying a product from out of the country, That is was an RX, it seems to be no longer allowed on Amazon.
After reading every review, I chose this one.
it's much better then Bio-freeze, and have used it many times. No weird smell or staining. It works, but I'm not fully there for this prroduct.
suggestion: I put on my Neck area when stiff, and found that it had a burning sensation.
