Sustained Energy

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.

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.

The original 320 calorie "mega" serving was way too big, which is the exact opposite of what we advocate - Less is best. In fact, about the only complaints we ever got was from over consuming. 180 calories per hour is much more in line with 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 easy. Each scoop is 100 calories, so three scoops will almost give you the same amount of calories.

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.
