What is the benefit of making a multi-hour bottle of Perpetuem, and how do i make it?
While athletes love how Perpetuem works, many do not like to drink large volumes of flavored liquid hour after hour. Making Perpetuem in a bit more-concentrated, multi-hour bottle will resolve that, with most athletes making a bottle that contains 4 hours’ worth of Perpetuem. Here’s how to do it:
Each scoop of Perpetuem 2.0 contains 90 calories. Athletes weighing ~200 pounds, may use up to 2.25 scoops an hour, which supplies 202.5 calories. For light-weight athletes, 1.0 scoop (90 calories) to 1.25 scoops (112.5 calories) per hour works well. Medium-weight athletes will find that 1.50 scoops (135 calories) to 2.0 scoops (180 calories) per hour is an excellent amount.
Using the larger athlete as an example, start with the water bottle about 1/3 filled with water, add a couple of scoops of Perpetuem, but the lid back on the bottle and shake vigorously. Repeat the process until 9 scoops of Perpetuem are thoroughly mixed in the bottle. There are now 4 hours of fuel in one bottle, which benefits in two primary ways:
1. You don’t have to drink so much volume of flavored liquid hour after hour. Because you have 4 hours’ worth of fuel in one bottle, you only need to drink ¼ of the bottle every hour, augmenting that with plain water from another source (another water bottle, hydration pack, etc.) to take care of your hydration needs. Many athletes find that plain water quenches their thirst better than liquid fuels do, and drinking water to cleanse the palate makes taking another drink of fuel even more palatable.
2. Because you have 4 hours of Perpetuem in your bottle, you don’t have to stop and make more every hour, which saves a lot of time.
HOT TIP: Using a Sharpie permanent ink pen, mark your bottle off into 4 equal segments so that you have a visual of what line you need to drink down to every hour.
NOTE: If the weather is going to be hot, make your 4-hour bottle the night before and put it in the freezer. This is perfectly acceptable, and it will keep the mixture cold for a longer period of time.
Why did the serving size change?
The original 270 calorie serving was too big, which lead too many people down the path of excess calorie intake, which is the exact opposite of what we advocate - Less is best. In fact, about the only complaints we ever got was from consuming too many calories per hour. 180 calories per hour is close to what most athletes find works best, with some needing a little less and some needing a little more. Starting with one serving per hour and adjusting up or down for individual needs makes things a lot easier to find your ideal hourly caloric intake.
For those wanting to get back to the original serving size, it’s very easy. Each scoop is 90 calories, so three scoops will equal 270 calories.
How soon after mixing Perpetuem does it need to be consumed?
In moderate temperatures, a pre-mixed bottle of Perpetuem should be suitable for consumption for up to 5 hours, perhaps even slightly longer. In warm-to-hot weather, that consumption “window” will be shorter, as short as 2 hours in very warm weather. Freezing your pre-mixed bottle(s) of fuel the night before will extend their palatability (i.e., staying colder longer) and keep the mixture suitable for consumption for a longer period of time.
How should i mix Perpetuem for a hot-weather event?
If the weather is going to be mild-to-warm you should make your multi-hour bottle(s) of Perpetuem the night before and freeze them. If, for example, you’re doing an iron-distance triathlon you can put both bottles on the bike or leave one at Special Needs. If you’re doing a 6-hour cycling event, you can carry both bottles on the bike. If you’re doing an ultrarunning race, you can carry one and have the other in a small cooler at the “bag drop” aid station.
If it’s going to be hot on your iron-distance triathlon, freeze your first multi-hour bottle of Perpetuem. Freeze the second bottle as well, but prior to putting it in the freezer, wrap a wet face cloth or rag around the bottle and secure with a couple rubber bands… then stick it in the freezer. This second bottle will end up having a frozen face cloth/rag around it, which provides extra insulation to help keep it cool. This second bottle will go to Special Needs. This is also a good strategy for ultrarunners who have a “bag drop” aid station. Carry the first frozen multi-hour bottle with you, and pick up the wrapped-frozen multi-hour bottle at the bag drop aid station.
If the weather is going to be extremely hot on event day, make up and freeze your first multi-hour bottle of Perpetuem 2.0 and carry with you on bike or body. Have the second one waiting for you, dry powder only in a bottle at Special Needs (triathlon), on your bike (cycling events), or at the “bag drop” aid station (ultrarunning). You will have to stop briefly to add cold water to the powder-only bottle and spend a little time getting it mixed. However, this is time well invested because you will have a fresh bottle of cold fuel to cover you for the next several hours.
Is it okay to mix Perpetuem and keep it refrigerated?
It is perfectly acceptable to mix bottles of Perpetuem ahead of time, though for maximal potency we recommend consuming the pre-mixed bottle(s) within 48 hours’ time once mixed. Freezing the mixture is also completely acceptable, and there is no time limit on when you need to consume frozen Perpetuem. You may notice a small amount of crystals at or around the top of the bottle. This is due to the l-carnitine component in these two fuels, which is very hygroscopic (has an affinity for water). L-carnitine formed crystals may signal a slight reduction in potency of this amino acid; however, this crystallization effect is normal and harmless, and the product is perfectly acceptable for consumption.
How do i determine the equivalent of one scoop of Perpetuem?
No scoop? No problem! With the following conversion information, your "Where did my scoop go?" problems are resolved!
Perpetuem 2.0
1 Level Scoop (39cc) = 2 TBSP +1 ¾ tsp (Serving Size: 2 Scoops)
Perpetuem Classic
1 Level Scoop (60 cc) = 4 TBSP + ½ tsp (Serving Size: 2 Scoops)
What is the difference between Perpetuem and Perpetuem solids?
Perpetuem Solids are made from the same corn maltodextrin formula as Classic Perpetuem powder. Each 3 tablet serving provides 100 calories, 10 more calories than 1 scoop of Perpetuem powder. Perpetuem Solids can be used as the sole source of calories, but most athletes use them as a supplemental fuel that gives them something to chew on without resorting to gummies (aka candy) or other solid foods that will slow digestion and can lead to GI distress.
150 - 180 total calories per hour is the “sweet spot” for most athletes and Perpetuem Solids provide a novel way to help you hit this target.
Can Perpetuem and Heed be used in a hydration pack's bladder?
Q: Can Perpetuem and HEED be used in a hydration pack's bladder without clogging it up?
A: While both products can be used in a hydration pack bladder, because Perpetuem is a bit thicker by nature--with its complex carbs, protein, and healthy fat--it has the greater potential to clog. HEED is just an all-carbohydrate fuel, no protein or fat, so it's easier mix in and consume from a hydration pack.
Does Perpetuem contain caffeine?
Caffe Latte flavour contains 30 mg of caffeine per serving.
Can my teenagers use Perpeteum?
Q: Can my teenagers use Perpeteum during their longer workouts and events? They get very hungry and needs the calories but doesn't want to eat food and bog down. This seems like a perfect product for that.
A: Perpetuem is an absolutely ideal fuel for teenage athletes! We like to refer to Perpetuem as a "meal in a bottle" fuel, as it contains complex carbohydrates, protein, and a small amount of healthy fat, and it's superb for fulfilling energy requirements, while also staving off hunger pangs.
Is Sodium Phosphate, found in Race Day Boost and Perpetuem, safe to consume?
Yes, sodium tribasic phosphate (also referred to simply as sodium phosphate) is remarkably safe, especially in the relatively small amounts found in Race Day Boost and Perpetuem. Sodium phosphate enjoys FDA "GRAS" (Generally Recognized As Safe) status as an emulsifying agent, Nutrients and Dietary Supplement, a sequestrant (a food additive whose role is to improve the quality and stability of the food products), and for miscellaneous use.
The LD50 of orally dosed sodium tribasic phosphate for rats (the amount of an agent that is sufficient to kill 50 percent of the rats) is 7,400 mg/kg. Translated for a 75 kg/165 lb. athlete, that would mean a dose of nearly 555 grams (555,000 mg), an astronomically high amount that no one would even conceive of trying to take. By comparison:
The LD50 of sodium bicarbonate (baking soda) for rats is 4,220 mg/kg
The LD50 for rats consuming acetic acid (vinegar is a dilute aqueous solution of acetic acid) is 3,310 mg/kg
The LD50 of sodium chloride (table salt) for rats is 3,000 mg/k
Is the Soy Protein in Perpetuem Non-Gmo?
The soy protein isolate used in Perpetuem is GMO-free.
How can i prevent any clumping from happening when mixing my fuel bottles?
Always start with about one-third of your water bottle/blender bottle filled with water. Adding water to dry powder will oftentimes cause clumping, but if you first start with water and then add the powder, this issue will cease to exist. Once you’ve added the powder to the water-containing bottle, put the lid on and shake vigorously. After that, add a bit more water, put the lid on, and repeat the process. Continue until your fuel bottle is full. Note: This is especially important when you’re making a multi-hour bottle of fuel; make it a little bit at a time—add some water, add powder, put the lid on, shake, repeat.
How to use
1–2 scoops per hour as a primary source of calories as follows:
One Hour Bottle
Add 1–2 scoops to 12-20 oz (355 – 591 ml) of water.
This option is most effective when resupply is accessible, such as on-lap courses or when using a follow vehicle. Otherwise, mix bottles when refueling. Carry extra servings of dry powder and blend more as needed.
Multi-Hour Bottle
Mix 2–8 scoops in a water bottle. Take small sips every 15– 20 minutes. Augment with additional water and electrolytes from separate sources to meet your hydration and electrolyte needs.
Paste
Gradually add water to 2–4 scoops of Perpetuem 2.0 to create a thick, paste-like consistency. Fill Hammer Flask or other container with the concentrate.
Each flask can generally supply you with 2–3 hours of fuel. Augment with additional water and electrolytes from separate sources as needed.
Pro tips
For exercise lasting three hours or more, use from the outset.
Perpetuem 2.0 contains no artificial preservatives. To avoid spoilage, do not premix or leave unrefrigerated, especially in warm weather.
INGREDIENT BREAKDOWN
2.0 = TAPIOCA Maltodextrin – Non-GMO and unsprayed, tapioca is the king of complex carbs! Far less processed, guaranteed no GMO content, lower mono and disaccharide content/much higher percentage of polysaccharide content (courtesy of its lower Dextrose Equivalent), less sodium content, and even closer to the desired neutral pH, tapioca is the sugar and corn alternative we’ve been wanting to bring to you for years is finally here!
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.
Soy Lecithin – The extract from soybean oil, lecithin is an easily digestible source of healthful fat. This helps create a feeling of satiety and also supports the body’s natural fat-burning capabilities.
Sodium (Tribasic) Phosphate – This compound enhances the functioning of all three of the body’s ATP-producing energy systems—the short-term ATP-CP system, the medium-term lactic acid system, and the long-term oxygen/aerobic system.
A primary benefit of sodium (tribasic) phosphate is its ability to buffer blood acidity and help maintain a more ideal acid-alkaline balance by neutralizing excess hydrogen ions within the muscle cell. Effectively buffering lactic acid extends energy production within this system. This nutrient also increases 2,3 diphosphoglycerate (2,3-DPG). This compound, found in red blood cells helps release oxygen from hemoglobin into the muscle cells. An increase in 2,3-DPG will improve the availability of oxygen to working muscles during exercise.
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 – L-Carnitine Tartrate is 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.
Stevia – A natural, calorie-free sweeter derived from the leaves of Stevia rebaudiana, a plant native to Central and South America. It does not affect blood sugar levels or contribute to tooth decay like sugar does.
Chromium Polynicotinate – This trace mineral helps regulate blood sugar and plays a vital role in energy production.
Energy Smart® (Grape Juice, Rice Dextrin) – This all-natural, low-sugar sweetener plays an important role in Hammer Gel’s delicious flavor while contributing minimally to the overall carbohydrate content. Energy Smart® is certified non-GMO, gluten-free, and allergen-free.
