You need to find out where you are with Perpetuem. Maybe a full dose is too much? Maybe too little? I usually use HEED early on and then switch to a HEED-Perpetuem mix later on during a ride. Everybody is different. Find your mix, then enjoy the ride. Ive been using Hammer products, namely HEED and Perpetuem for quite a while (20 years) and Ive found my "mix". Once you find your sweet spot you will be good to go. I like to get my calories and nutrition from a liquid and not a solid as I don't want to have to waste energy digesting solids during a long ride. Hammer is science for endurance athletes. You do the fine tuning.


Been using "during ride" drinks since the late '90's along with water. I tried a lot of them and Cytomax and Endurox were my favs for years. Maltodextrin (simple sugar: "energy") is the go to ingredient in everything, it's cheap, easy to produce, etc. But it's not good for you (stomach issues for some of us, "processed", etc. Been using Hammer Nutrition (gels, Recoverite, etc.) since late '90's and have always been happy. NOW finally they got rid of the processed corn syrup (causes inflammation) and replaced with tapioca. Got "Cherry Bomb" flavor with caffeine and LOVE it. Mild cherry flavor is good. If they got rid of the Xylitol it would be perfect. Thanks Hammer Nutrition.

I've been using Perpetuem for several years now. For me, it has an improved taste over its predecessor. But the biggest improvement is how much easier it is to mix and dissolve. Although it can take some time by hand, I now also use a battery-operated frother. I put one scoop of Perpetuem in about 4 ounces of water, froth to mix it, and put it in the refrigerator. Just before I set out on my bike ride, I drink it. That mix and balanced electrolytes in my water bottles pretty well carry me through a 45-mile ride with my club. 32 servings turn into 64.
