MyHusbandandIhavebeentakingSierraSilfor7years. We first heard about SierraSil on the Shell Busey show and how it helped him. We both had a lot of soreness and stiffness in our knees and also in my lower back. After using SierraSil for 2 weeks we found amazing relief in our symptoms. I highly recommend SierraSil, it is a great product.
Thank you from a happy customer!
