KRI have tried energy gels from many… I have tried energy gels from many well-known brands, but the only one that felt smooth and effective when ingested was SIS. It seems to be the world's best brand of energy gel. Due to the brand awareness as well as the quality of the product, you can trust it and see it consumed by many athletes, including European soccer players, runners, marathoners, and swimmers. Highly recommended!!
