Wow, i happened to come upon this site just looking for samples of anything and this was my first sample to come in... at first i was going to give it to my parents but i have been having back pain and decided i would use it myself and if it works as good as i have seen other testimonials claim then i would order it for my parents once i get the money I honestly didn't expect anything from this, maybe like the effects of icy hot gel where it feels good for about 10 seconds and then it hurts again, i was incredibly excited when i applied this to my back I immediately went out and told my parents about it and told them that this stuff is crazy I don't know how it works but its amazing haha...anybody with ANY SORT OF PAIN I HIGHLY RECOMMEND THIS TO!! This product is a must have, I know it sounds like just another crazy miracle product but it actually works, truly amazing i will definitely be ordering a tub of it when I get the money to do so, but it will last a while I know because it does not take much at all to help just a dab of 2 fingers and then rub on your sore area.
