They can’t be approved by FDA because they contain no drugs/chemicals. Clinical studies on LifeWave phototherapy have been ongoing for 20+ years. Interesting and detailed data available if you search for it.
What I’d like to see more of is reactions people are having to each patch if they can trace it to the patch. After 12 months using X39 and experiencing remarkable, multiple results we added another patch. My blood pressure has always been normal and steady. Suddenly it’s high…..unusually high. There’s no resource or information through LifeWave that shares this info among users.
