I have been using NeuroStim for a while now and nothing compares to the clean energy and focus this gives me. I work in healthcare and often need to stay well past my shift times due to being short-staffed and this stuff keeps me going with a bright mood and ability to stay on task. I also use it before playing ball and it helps me keep my head in the game. It’s getting harder to find the product and I’m so happy to have found it here. No product that I’ve tried even comes close to this.
