Hammer Energy Gel
I really like Hammer Nutrition products. They've got what you need, and not much more. They don't go too nuts on the flavoring, which is great. The Complex Carbohydrate Energy Gel really does the trick when you're bonking. These gels taste good, and get you're energy up quickly. My personal favorite flavors are Espresso and Apple Cinnamon, which tastes a lot like a delicious gooey apple pie!
