Glukos Energy Gel 12 Pack. With Glukos Energy Gel fueling your ride, going the extra mile has never been easier. Featuring incredible energy that's also incredibly tasty, at their core these gels are made with glucose. This simple sugar molecule is absorbed immediately resulting in instant energy while other sport fuels use inferior sugars such as fructose and sucrose that have to be digested before they can provide any benefit. This process wastes valuable time, and even robs your body of energy. So if you want to push yourself to the limit these gels can help you go the distance.
