I was experiencing debilitating symptoms following a Delta , COVID-19 infection. The fatigue and heart palpitations made it difficult for me to work and enjoy my life. One week after daily use of X-39 patches I noticed I had less heaviness in my chest and could breathe easier! I even worked a 12-hour shift! Is it a miracle for everyone or every condition? I am not promising. Does it bring improvement? So far so good!
