Perpetuem®

HEED is a “carbohydrate only” drink mix that is great for bouts of exercise up to 2-3 hours in duration. Perpetuem 2.0 is a “carb + protein + healthy fat” drink mix that is ideal for longer-duration workouts and races. The inclusion of protein in Perpetuem helps to satisfy the 10-15% of energy that must come from protein/amino acids during long-duration exercise. Without this protein donation the body is forced to cannibalize its lean muscle tissue to satisfy this small percentage of energy requirements. That decreases exercise performance, due to the excess amount of fatigue-causing ammonia that is produced, and it will also cause recovery after exercise to be significantly longer because there is a greater percentage of broken down muscle tissue that needs repairing. The healthy fat added to the Perpetuem formula gives the body a cue of sorts to let it know that it’s not depriving it of fat (the “you have to eat fat to burn fat” train of thought). As a result, the body releases its fatty acid stores more liberally so that the calories from them can be used to create energy more consistently and efficiently. As you can see, Perpetuem is a very complete “meal in a bottle” fuel for endurance exercise.

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.

In moderate temperatures, a pre-mixed bottle of Perpetuem or Sustained Energy 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.

It is perfectly acceptable to mix bottles of Perpetuem or Sustained Energy 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 or Sustained Energy. 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.

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)

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.

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.

Q: I know that Perpetuem is best when used no longer than 3 years after manufacture, but what is the “best used”  time frame once opened?

A: The "best by" date that extends from the manufacture date (listed as ""MFG"") is the length of time the product will retain maximal potency once opened. Be sure to store your container(s) of Perpetuem away from direct sunlight, moisture, and excess heat, and it will be completely potent for 3 years, possibly even longer.

Caffe Latte flavor contains 30 mg of caffeine per serving.

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.

The soy protein isolate used in Perpetuem is GMO-free.

Q: What is the source for iron in Perpetuem? Is it from the soy or additional additives?

A: The 1 mg of iron that you see on the labels of all flavors of Perpetuem 2.0 and Perpetuem classic is for a 2-scoop serving, and it is what naturally occurs in the soy protein and soy lecithin in the product. No iron has been added.

Q: I cannot consume soy. Is there a recipe for a soy-free Perpetuem?

A: Yes, you can make a non-soy endurance fuel that’s comparable to Perpetuem by using HEED and Vegan Protein:

Each 2-scoop serving of Perpetuem contains 180 calories from 34 grams of carbohydrates, 5 grams of protein, and 2 grams of fat. To make a soy-free version that’s similar to Perpetuem, mix together the following:

• 1.25 scoops of HEED = 137.5 calories from 35 grams of carbohydrates
• 1/3 scoop of Vegan Protein = 40 calories from 2.5 grams of carbohydrates, 6.5 grams of protein, and 0.67 grams of fat

TOTAL CARBOHYDRATES – 37.5 grams
TOTAL PROTEIN – 6.5 grams
TOTAL FAT – .67 grams
TOTAL CALORIES – 177.5

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.
