Query: It bloody well works!

I did not think BIOFREEZE would work, and now it is a staple part of my gym bag.The smell is atrocious but ephemeral and the feel is a bit "interesting" as it goes on—sort of a dry liquid, if that makes any sense.Nevertheless, the penetrative cold seems to reach down into the muscle itself and loosens the pain. I tried it on my thumb which was sore from dead lifts and in one overnight application, it was gone. Another, but this time several, applications to the right knee which was not just sore but may have been strained, and poof! gone.I will swear by this product, it's excellent.
