Darwin W. - Calgary, AB*


I am a 68 year old renovating carpenter and physical work has taken a toll on my body – repetitive movement and heavy lifting. I suffer from back, arm and leg weakness and discomfort. A carpenter like myself mentioned he had similar symptoms and even worse than mine, said “I swear by a product called Joint Formula 14”. He was so serious I had to try it. In the course of one week I had much better movement and comfort, also less discomfort if I work longer or harder, during a work day.

I certainly recommend SierraSil to physically active people with work related trauma.
