Mixing Options

You can mix and consume Sustaind 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: This method works best in training or racing situations where you have a support crew and vehicle. They can keep your mixed bottles chilled and prepare fresh bottles of fuel along the way. 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 drink. 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. Either way, with or without a support crew, to make the one-hour bottle, mix the suggested number of scoops of Perpetuem for your bodyweight in a small (20 ounces) or large (24-28 ounces) water bottle. Consume one bottle hourly.
  • The Multi-Hour Bottle: This is by far the most convenient method of fueling because it allows you to be self-contained 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. You need a 6-hour fuel supply. Multiply the number of scoops you need by the hours that you will be exercising (in this case 1.5 scoops x 6 hours) and place in a large bottle with as much water as will fit. You may need to add a few scoops at a time to get it all to mix well. Then "nurse" this bottle, taking small sips every 15-20 minutes. In this concentration, the water in the mixed bottle does not contribute more than a couple of ounces to your hourly fluid intake needs. To meet your fluid requirements, carry a second and possibly even a third bottle of plain water, or 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 16-24 ounces of plain water per hour. When using the multi-hour bottle, 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, this is your best option. Sustained Energy can be made into a super-concentrated, near paste-like consistency and dispensed from a small 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. Depending on how many scoops per hour you have determined you require, and based on 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.


Q: How soon after I make Sustained Energy or Perpetuem do I have to drink it?

A: Ideally, it should be within 3-5 hours, with up to perhaps 6-8 hours (depending on the temperatures) being the longest we recommend. Dr. Bill Misner explains: "Energy drink powders (such as Sustained Energy and Perpetuem) containing no preservatives are predisposed to change once set in solution mixtures. Time, temperature, humidity, environmental airborne or endogenous microbes, oxidation factors may cause fatty acids to turn rancid or proteins to "sour" in the presence of long chain or short chain carbohydrates. A prime example is found in pasteurized milk. Milk typically sours in stages as one type of bacteria is replaced by another. Bacilli convert protein into ammonia products, and the pH rises. The odor or taste of spoiled milk is apparent once this has happened. We have observed this phenomenon in our soy-based products, Sustained Energy and Perpetuem if the product is mixed prior to an event then not kept cold or consumed within 3-5 hours.

Athletes should be encouraged to keep pre-mixed protein-enhanced or lipid-containing carbohydrate drinks under 59° F (15° C) or ideally at a cooler 40-45° F (approx 4.5 - 7.25° C) in order to keep fermentation of environmental bacteria from proliferating in the drink mixture. Freezing the drink the night before an event may result in keeping the macronutrient contents intact and inhibit bacterial growth potential. Once the drink is soured to taste or has become noxious to olfactory sensed odor, then it is advised that the drink not be consumed."

Q: If I mix Sustained Energy or Perpetuem and keep it in the refrigerator for a day or two, will it break down any of the desired properties due to sitting for a while and not being used right away?

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 possibly after mixing.

Q: Can I use Sustained Energy or Perpetuem in a hydration pack?

A: You could but we don’t recommend this practice. First, neither Sustained Energy nor Perpetuem contain any preservatives and as a result, the protein component tends to separate after awhile and may settle on the bottom if the mixture is not agitated on occasion. Keeping a carbohydrate/protein fuel thoroughly mixed can be difficult to do when using a hydration pack. Also, when you mix the product in a water bottle you’re better able to see exactly how much you’re consuming. Lastly, cleaning the bladder of any hydration pack is substantially easier when you use it for drinking water only. Our recommendation is to use water bottles to mix Sustained Energy and Perpetuem and hydration packs for water only.

Q: I’m doing a full iron-distance triathlon and the weather is going to be hot. I want to use Perpetuem for the bike portion. How do you suggest I mix it so that it doesn’t get warm and unpalatable? 

A: For the sake of an even number, let’s say the bike portion will take you six hours to complete. 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 is the amount you need to fulfill an hour’s worth of fuel requirements, you make a 6-scoop bottle. You now have three hours of fuel in one bottle, which means that you need only drink 1/3 of that bottle every hour, augmenting that with plain water (approx 20-28 fluid ounces/600-830 milliliters per hour) from another source, such as another bottle or hydration system. Make two 6-scoop bottles and you’ve got your six hours worth of fuel taken care of.

If the race day weather isn’t going to be too terribly hot, you can make both 3-hour bottles ahead of time and freeze them the night before the race. That will allow them to stay 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, we suggest making one 3-hour bottle of fuel the night before the race and freezing it. The other 3-hour bottle that you’ll carry on your bike (or have waiting for you at the halfway point/special needs area) will contain DRY POWDER ONLY; it won’t be premixed in water. Yes, when your first 3-hour bottle of fuel is finished you will need to stop, dismount your bike, and take a few moments to add cold water to this second 3-hour bottle of powder and get it thoroughly mixed. However, this is time well invested because you now have a fresh bottle of fuel, one that’s cold and very palatable, to take care of your fuel requirements for the second half of the bike portion.

One athlete who recently completely Ironman Australia did just that and wrote us saying, "I did as you recommended - had the second bottle of dry Perpetuem powder in my bike Special Needs bag, and just added cool water. It only took 30 seconds or so and I was underway with a bidon of cold Perpetuem for the second half of the bike. Great suggestion, it works like a treat!"
