Nine years ago I was diagnosed with a terrible joint condition that made it so I could barely walk. I injected myself with methotrexate. After 8 years I wanted to get off all medications and I heard about SierraSil and weaned myself off drugs and started taking the powder form. Now 6 months later I have a ton of energy and sleep a whole lot better. So far I swear by SierraSil. Thank you!
