They charge a large amount of money and the product does not work.When trying to return as their guarantee states, they will not honor it.

I was very disappointed after trying the product for the 30 days as they required. The pain did not diminish. I was on glucosamine before and that is fairly inexpensive and worked pretty well. THey claimed that this would work much better and that just wasn't the case.

Also be aware that it causes much stomach irritation due to the cayenne pepper that they have in this product as well.Very very disappointed.
