I herd about the X 39 patches from my dad, who was already trying out the patches that brother sent him to try. So far he has gotten more energy, the purple varicose veins on his feet and legs are going away, and he is getting better sleep from wearing the patches. So my dad gave me 7 patches for me to try. After four day of using the patches I have more energy. That is all I have noticed so far, but I hope that continuing to wear the patches that it will help with the carpal tunnel pain of the wrist a elbow on both hands and arms, rebuild up my metabolism to lose weight, get better sleep and have better range of motion all around. I just wana feel like a kid again and not be so tired all the time.
