First Endurance EFS and Ultragen are an unbeatable combo, and truth be told we couldn't imagine using one without the other. Drinking EFS and using EFS Liquid Shot while you ride lets you maximize your endurance and energy so you can make the most of your training, while drinking Ultragen after you ride facilitates the sort of complete recovery you need to hammer yourself again the next day. Since they're such a potent tag-team, we've packaged them together here so you can take care of your energy drink needs in one click -- and save some money at the same time. By buying them together you'll save 10% in comparison to buying them individually. You get one canister of EFS in Fruit Punch, Grape, Lemon-Lime, Orange, or Tangerine; one canister of Ultragen in Cappuccino, Orange Creamsicle, or Tropical Punch; and one 6-pack of EFS Liquid Shot in Vanilla. You'll also get one bottle of Optygen and one bottle of Multi-V, so you've got your energy and nutritional needs completely covered.
