GU Energy Labs

GU Energy Labs is the parent company of the Roctane Ultra Endurance brand. GU Energy developed Roctane as the performance energy choice for ultra endurance athletes. The first Roctane Energy Gel was designed and tested 6-7 years ago by athletes competing in the Hard Rock 100 Ultra Marathon trail run who needed a portable, efficient and effective energy source for an event that can last over 24 hours. Since then GU Energy Labs has continued to work with these same ultra endurance athletes to develop and expand the product lineup so athletes can continue to go fast and far.
