History and Usage: Redline Power Rush is a sugar-free, carb-free and zero calorie ready-to-drink energy product with an exceptionally small serving size, one-half of the tiny 2.5 oz. bottle. That makes Redline Power Rush a much more discreet and easy-to-use product than the familiar energy drinks that come in much larger cans and require you to drink much more product to get the effect you want. Like the Chaser drinks, Redline Power Rush uses a blend of caffeine, amino acids and vitamins to give you long-term sustained energy, not a temporary caffeine-and-sugar buzz after which energy levels crash. Redline Power Rush may be a small product, physically, but it's a powerful formula that should be used carefully, not recklessly. Be aware that a full bottle is actually two servings, so be sure to asses your tolerance to a single serving of Redline Power Rush before experimenting with higher doses.
