Activate Your Stem Cells. As we age, our stem cells decline in their ability to heal our bodies. Imagine if we could activate our stem cells and reset them to a younger, healthier state. This would be healing in a completely non-invasive, safe and cost-effective way. Discover the synergistic benefits of X39® + X49T in the LifeWave Performance Bundle. Using both patches together, you trigger a multiplier effect that supports performance and shortens recovery time, allowing you to do more, do better and do faster. LifeWave X39 and X49 Performance Bundle – 30 Patches of each, in separate pouches.
