I was given a sample of Real time by a distributor in our park. I have used it on my lower back, shoulder and wherever else may be hurting. This stuff works!! I used to use Bio-Freeze that was recommended by my Chiro in Michigan, this works much better, smells better etc. I often joke that I wish it came in a 55 gallon drum so I could bath in it. Try it, you will see for yourself!
