Unless you complement your carbohydrate source with protein, your body will start to digest its own muscle tissue (for protein) for energy after about 90 minutes of hard exercise. When your training takes you beyond the range of Hammer Gel alone, you can rely on Sustained Energy with its 7:1 carbohydrate to protein ratio. Sustained Energy contains a superior blend of complex carbohydrates, a precise amount of GMO-free protein, and a few carefully selected micronutrients that all work synergistically to provide consistent, long-lasting energy. With Sustained Energy, you'll have 100% confidence in your fuel, even during your longest and hardest training sessions and races. Without any added flavoring or sweeteners, it has a pleasant neutral flavor.
Since 1992 Sustained Energy has stood the test of time in every conceivable endurance and ultra-endurance event. No matter how difficult or lengthy your exercise or race is, Sustained Energy will come through every time, and keep you going mile after mile, hour after hour.
Hammer Nutrition's original long distance fuel, Sustained Energy has attained a legendary status in the world of endurance sports since its introduction in 1992. Tested and proven in virtually every endurance event on the planet, Sustained Energy, with its unique 7:1 carbohydrate to protein ratio and it's neutral flavor is still the first choice of thousands of athletes. After about two hours of exercise, you need to have some protein in your fuel or you will start to cannibalize or break down precious muscle tissue. So when your exercise goes beyond the range of Hammer Gel or HEED alone, Sustained Energy is ready to serve you, providing premium fuel complemented with specific nutrients that support enhanced fat utilization and lactic acid buffering.
Give Sustained Energy a try—you'll have 100% confidence in your fuel—and you'll understand why it's been the choice of thousands of endurance athletes for well over a decade. For maximum fueling variety and flexibility during your longest and hardest training sessions and races, mix or alternate Sustained Energy with Hammer Gel, HEED, and/or Perpetuem.
This unflavored product is ideally suited for athletes who want calories with as little taste and sweetness as possible. In addition, soy protein ensures that minimal ammonia will be released into the muscles, further reducing fatigue and tissue damage.
You can make a concentrated solution of Sustained Energy and "nurse" it for several hours, alternating with sips of plain water from another bottle. You can also flavor Sustained Energy with your favorite flavor of Sustained Energy with your favorite flavor of Hammer Gel.
HOW TO USE SUSTAINED ENERGY
Use as a primary source of calories during exercise/competition lasting more than two hours.
One serving equals three scoops of Sustained Energy and contains 320 calories (approx. 85 g).
Suggested Doses by Body Weight*
*These are estimated doses. Each athlete should determine in training, under a variety of conditions, their personal optimum.
If using more than one fuel, be sure to combine all of the calories from all of the products consumed to reach a correct total hourly intake.
Mixing / Usage Instructions
IMPORTANT NOTE: Due to potential spoilage issues, Sustained Energy cannot be premixed and left for several hours in warm weather. You can mix and consume Sustained Energy three different ways depending on individual preference and logistical concerns. Please experiment with the following options to determine which works best for you.
The One-Hour Bottle - Mix the suggested amount of Sustained Energy for your body weight (see chart above) in 475-825 ml of water. Consume one bottle hourly. This method is ideal when training or racing with a support crew and vehicle. If you're without a support crew, but still want to use this option for mixing, keep in mind that it's obviously less convenient as you'll have to stop more frequently to mix your fuel. Also, because you are trying to fulfill both hydration and caloric requirements from one source, you have limited ability to adjust one without affecting the other; you may need to consume additional water to satisfy hydration requirements.
The Multi-Hour Bottle - This is by far the most convenient method of fueling because it allows you to be self-sufficient for many hours, requiring only additional plain water along the way. The only limitation is how many scoops you can fit into a bottle. Determine your proper hourly intake of scoops by experimenting with the numbers from the dosage chart. Let's say you've determined through testing that 1,5 scoops of Sustained Energy per hour is your ideal caloric intake. For a 4-hour workout, you'll need (4 x 1,5=) six scoops in a bottle, filled with water and shaken. You may need to add a few scoops at a time to get it all to mix well. You then "nurse" this bottle, taking small sips every 15-20 minutes. At this concentration, the water in the mixed bottle does not contribute much at all to your hourly fluid intake needs. To meet your fluid requirements, carry a second and possibly even a third bottle of plain water, use a hydration system, or know where you can refill along your route. Drink according to the temperature/humidity and your exertion level so that you consume in the range of 475-825 ml of plain water per hour. This way, as long as you can obtain water along the way, you're set for hours of hard training.
Gel or Paste - If you want to carry the highest volume of calories in the least amount of space, making a thick mix is your best option. Sustained Energy can be made into a super-concentrated, near paste-like consistency and dispensed from a Hammer Gel Flask. Using a blender or bowl and spoon, mix scoops of powder with a small amount of water, gradually adding water as necessary to create the desired consistency. You can also add Hammer Gel or HEED for flavor if desired. Depending on how many scoops per hour you require, and how concentrated the mix is, each flask of Sustained Energy can supply you with 2-4 hours of fuel. As with the multi-hour bottle, you must carry additional bottles of plain water or use a hydration system to meet your fluid requirements.
By design, neither Perpetuem nor Sustained Energy contains artificial preservatives. Preservatives provide absolutely no benefits for athletic performance or general health. We consider them health hazards, in fact, which is why we do not include them in either of these products or any of the Hammer Nutrition fuels. As a result of this, however, once mixed into solution, the protein component in both Perpetuem and Sustained Energy is affected in the following ways:
At some point in time, it will eventually sour and no longer be acceptable for consumption.
It tends to separate after several hours and may settle on the bottom of a bottle or hydration pack bladder.
We believe that not having artificial preservatives in our products is far more important than these two inconveniences; however, they are factors that you need to consider when using Perpetuem or Sustained Energy.
