30 Servings: Net Wt. 2250g
Serving Size: 85g
The world’s first protein-fortified sports drink still stands the test of time. Designed to provide steady energy, buffer lactic acid, and prevent lean-muscle cannibalization, this unsweetened and mild-tasting 7:1 carb-to-protein blend has been a fan favorite since 1992. It is especially popular with ectomorph, hyper-metabolic body types with limited fat stores who struggle to maintain muscle mass during high-volume training.
BENEFITS
✓ Long-lasting energy
✓ Lactic acid buffering
✓ Lean muscle mass protection
✓ Vegan Friendly
✓ Certified Kosher
✓ No Sugar Added
Use as a primary source of calories during exercise/competition lasting more than two hours.
Serving Size
One serving equals three scoops of Sustained Energy and contains 320 calories (approx. 85 g).
Suggested Doses by Body Weight*
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 Perpetuem for your bodyweight (see chart below) in a 21-24 ounce (approx 520-710 ml) water bottle. Consume one bottle hourly. This method is ideal when training or racing with a support crew. If you're without a support crew but still want to use this option for mixing, keep in mind that it might be cumbersome as you'll have to stop more frequently to mix your fuel drink. Also, because you are trying to fulfill both hydration and caloric requirements from one source, you have limited your 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 2 scoops of Perpetuem per hour is your ideal caloric intake. For a 4-hour workout, you'll need 8 scoops in a bottle, then filled with water and shaken well. 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 to your hourly fluid intake needs. To meet your fluid requirements, carry a second or third bottle of plain water, use a hydration system, or know where you are able to refill along your route. Drink according to the temperature/humidity and your exertion level consuming between 16-28 ounces (approx 475-830 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. Perpetuem 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 consistency desired. If you're using the orange-vanilla flavor of Perpetuem, remember that the heavier and more concentrated you mix it, the sweeter and stronger the flavor will become. You may also add Hammer Gel or HEED to alter the flavor, if desired. Depending on how many scoops per hour you require, and how concentrated the mix is, each flask of Perpetuem 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.
Special Note on Perpetuem:
Due to this being a high concentration calorie source (via its complex carbohydrate, soy protein, and healthy fat components), Hammer Nutrition has noted that many athletes do well with a substantially lower calorie intake when using Perpetuem as their primary-to-sole fuel. Therefore, with this particular fuel Hammer Nutrition highly recommends starting with the lowest amount suggested-perhaps even a bit lower-and work your way up to a higher amount, if a higher amount has proved to be necessary via testing in training.
*These are estimated doses. Each athlete should determine in training, under a variety of conditions, their personal optimum.
Important information:
By design, neither Perpetuem nor ed Energy contain artificial preservatives. Preservatives provide absolutely no benefits for athletic performance or general health - Hammer Nutrition considers them health hazards, in fact - which is why they do not include them in either of these products, or any of the Hammer Nutrition fuels.
As a result of this, however, once mixed in solution the protein component in both Perpetuem and ed Energy is affected in the following ways:
Ingredients: Maltodextrin, Isolated Soy Protein, Amino Acids (L-Carnosine, L-Carnitine Tartrate), Choline Bitartrate, Chromium Polynicotinate. Contains:Soy. This product is processed in a facility that also processes dairy, egg, and wheat products.
Ingredients Breakdown
Maltodextrin
A high-glycemic index (GI) complex carbohydrate, ideal for providing fast-acting, long-lasting energy during exercise.
Isolated Soy Protein
A dry powder food ingredient that has been separated or isolated from the other components of the soybean, making it 90 to 95 percent protein, and nearly carbohydrate- and fat-free.
L-Carnosine
This dipeptide (a combination of two amino acids) L-carnosine is a potent lactic acid buffer. It also offers antioxidant support.
L-Carnitine Tartrate
A compound containing L-carnitine chelated (“bonded”) to L-tartrate, which is a salt of tartaric acid. L-carnitine is the key nutrient involved in the shuttling of fatty acids into the cell for energy production. Tartrate is a potent antioxidant.
Choline Bitartrate
A type of B-complex vitamin that helps with efficient use of body fat stores as energy. Choline bitartrate also supports enhanced cognition, learning, and memory.
Chromium Polynicotinate
This trace mineral helps regulate blood sugar and plays a vital role in energy production.
A: The effectual benefits ("desired properties") are not lost, but the l-carnitine in both products may deteriorate somewhat, forming crystals within the mix since it is very hygroscopic (has an affinity for water). The deterioration, if any, is minimal in 48 hours post-mix, refrigerated. However, for best results we recommend using ed Energy or Perpetuem as soon as possible after mixing.
Q: Should I Use Perpetuem Or Sustained Energy?
A: Hammer Nutrition offers two superb long distance fuels in powder form – Sustained Energy and Perpetuem. Sustained Energy (“SE” as it’s commonly referred to) was introduced in 1992 and its formula has remained unchanged ever since. Perpetuem first became available in early 2003. Both of these fuels are intended to be used as your primary or sole fuel when exercise goes beyond two hours.
Deciding whether to use Sustained Energy or Perpetuem (or both) will undoubtedly be influenced by personal preference; however, there are a few differences between these two time-proven fuels that can assist you in the selection process.
Q: Do Any Of The Hammer Nutrition Products Contain Brown Rice Syrup?
A: Hammer Nutrition does not use brown rice syrup in any of our products, so you have nothing to worry about with regards to Hammer Nutrition products.
Q: What Happens If I Mix Perpetuem Or Sustained Energy And Keep It Refrigerated?
A: The effectual benefits ("desired properties") are not lost, but the l-carnitine in both products may deteriorate somewhat, forming crystals within the mix since it is very hygroscopic (has an affinity for water). The deterioration, if any, is minimal in 48 hours post-mix, refrigerated. However, for best results we recommend using Sustained Energy or Perpetuem as soon as possible after mixing.
Q: How Soon After Mixing Perpetuem And Sustained Energy Do They Need To Be Consumed?
A: Let's say that the bike portion will take you six hours. You can make all six hours of fuel in two bottles. For example, if you have found (through testing in training) that two scoops of Perpetuem will provide an hour's fuel, put six scoops in and make a 3-hour bottle, fulfilling your hydration requirements with plain water (approx 20-28 fluid ounces/600-830 milliliters per hour) from another bottle or hydration system. Make two 6-scoop bottles and you've got your six hours worth of fuel taken care of.
Mix the bottles the night before the race and freeze them. That will keep them cold and palatable as they thaw during the bike portion of the race. If, however, the weather on race day is going to be very hot, or you don't have a way to keep the bottles cold until the bike leg, then try this method: mix and freeze one bottle as above, but in the other put only the six scoops of Perpetuem, and add no water.When you finish your first 3-hour bottle you will need to stop and take a few moments to add cold water to this second. It just takes a few seconds, but now you have a fresh, cold bottle of fuel for the second half of the bike ride. Using insulated bottles also helps, if you don't mind the slight extra weight.
