Dolphin Neurostim has been shown to dramatically help concussion recovery. It also helps reduce pain dramatically! Similar to neural therapy with out needles, it resets the electrical charges of the cells increasing ATP. This can be used to increase the function of any organ and reduce inflammation. If you have had surgery and still are having pain, if you have scars or tattoos and unresolved pain you should try the Dolphin Neurostim with acupuncture to reduce and eliminate pain and upregulate your whole body and brain!!!!!
