Id seen an interview with the runner/developer of this gum and had seen it in stores but was nervous/reluctant to try even though the concept sounds great.
I did purchase three flavors, used the bubblegum flavor in a half marathon this past weekend. I cant say that it made a performance difference, but it did make a distraction difference. I have 2 other packs I will use over the next week or two and I would for sure purchase more
