Hammer NutritionPerpetuem (32 Servings)(Return to Product Page)

There aren't all that many supplements with protein and fat, and Perpetuem works for me better than any I've tried, at a better price than most. I start taking in Perpetuem, at least in part, after about 3 hours and use it for rides up to 10 hours, which is kind of the upper end of me trying to ride without consuming 'real food'. Four stars instead of five because I don't love the texture and because of occasional mild stomach issues, but the latter could be simple exertional issues whereas the former is (I think) a commonality of all powders with fat and/or protein, so maybe I'm being unfair. Also, I wish they had a couple more flavor options. Anyway, after all that, I recommend this product.

This doesn't give me the syrupy sugar goo mouth like other mixes can on long rides a few hours or more long. I like that it doesn't contain the typical sugars so it doesn't create insulin response issues or promote tooth rot. The flavor is just enough ( I like the orange ). On race day it's not my choice though, I switch to the sugar mixes for easier digestion / absorption and I have electrolytes in the mix. I'll do a couple long training rides with the sugary mixes before the race to make sure my stomach is ready for it.

I used 2 servings of this today and I literally couldn't bonk. I stopped taking water and salts to try to stop my workout but kept running for an hour and a half after. I did 58 miles on the bike and 16.2 miles on the treadmill, and this was 6 days off a marathon. Usually I feel defeated after a longer workout but I noticed a much better state of mind as well.

I use Perpeteum in longer rides, keeps me fueled without having to stop and eat. I still carry other real food but this is great

Use it on all ultra rides. Great liquid fuel to supplement the solid food eaten during these events.

I first began using Hammer Perpetuem while training for a grueling five day ride in the Negev Desert. I knew that the ride itself would require supplemental calories and protein to preserve muscle strength over the long haul. I had previously relied on gels and energy drinks which were largely sugar and electrolyte based and knew that I needed more substance to deal with the desert heat and climbing. I like the added boost that Perpetuem provided particularly on back to back hard rides that I used it more and more as the training intensified. Now that I have completed the ride I see Perpetuem as a mainstay of my training nutrition regimen and a must for long multiday rides.

For all my bike rides in excess of two hours, this is what I mix into my aero-bottle. I still supplement with endurolites or other electrolyte supplement.

Each time I use this product, I see to burp a lot... Not sure at this time if it is all that different than other, similar products.... Still hoping for more results.

Great products

Chocolate flavor mixes things up and does not leave as much after taste as other flavors.

My local bike shop said their distributor was out of stock. Western Bike works had the flavor I wanted in the big can for a good price. Added chamois cream to order to get free shipping.

This has been the missing link. I typically use electrolyte drinks like cytomax on long (over 2hrs) rides. However, I still bonk here and there. After using Perpetuem, Im able to ride for much much longer when I use it as directed (4hr-8hr rides).

I take this on days when I'm going to be in the saddle for 4+ hours. This powder helps me power thru to the end.

I first experienced this product when my LBS suggested me a trial pack before a training ride. Since then I have relied on this to keep me going on any my 60 mile ride where the pace is expected to remain in the mid 20's. I can't digest much in the early mornings, so if I need a little push to help sustain me on the weekly group rides that almost rival a cat 4-3 type training race, I will also occasionally use Perpetuem for these shorter but stout rides.

I can no longer find my favorite coffee flavor, but the typical orange cream works well. I like the fact that it is a natural product and will go bad after preparation if not consumed in a couple of hours. I'm always worried of foods that never expire.

A friend who is an ultra marathoner recommended this product to me after I mentioned that I sometimes just seemed to hit the wall very quickly on some of my longer bike rides (4-6 hours). Often I need to pack all of my own foodcalories because there are no stores or other sources of food in the remote areas where I most like to train.

Perpetuem has been a nice discovery. It provides long lasting energy, can be carried in several forms (in your water bottle, as paste in small flask, or as powder), and won't make you nauseous. If you have water sources along your route you can go a long long way without packing a lot of weight or bulk (you MUST take in a considerable amount of water along with Perpetuem or you won't be able to digest it).

My friend also recommended that I read through the Hammer website. I hadn't paid a lot of attention to nutritional needs before but found the Hammer documents to be outstanding. They gave me a much deeper understanding of the general needs of long distance cyclists as well as how those needs could be met by specific Hammer products.

I use this product for longer biking events, lasting over 2 hours. Consistency is smooth when well mixed. I have tried both flavors and both taste creamy without much hint of orange or strawberry. I notice a difference when I use this product in that I am stronger at the finish of rides. I recommend this product for what it does, however if you want something that tastes good find another product.

I take this with me on every ride over 10-15 miles. I use the orange-vanilla flavor (creamsicle -) It tastes good, you can use it in place of gels, and it can even replace food in a pinch. It has 7gr protien, 54gr carbs in 2 scoops. It can be a real life saver! Great stuff. Hammer is the best. I am just a loyal Hammer fan. They use good ingredients, very well thought out.

I use this for fuel on longer rides (2.5 hours plus). I use to eat bars but the higher sugar level in the bars I was eating (about 22 grams) was causing me to have swings in energy to power the ride, especially when I would eat 2 bars on a longer ride. What I found happened when I stopped the bars and switched to Perpetuem is I no longer had swings and feeling like I lost my power output. Perpetuem helps me to continue strong power output in that third and fourth hour of riding when my original energy storage at the beginning of the ride is depleted. I assume because it is a liquid fuel it goes into the body faster than food too but I can't say if that is true but that what I perceive. I usually don't start drinking Perpetuem until I am in the beginning of that third hour but I assume this would be different for everyone depending on your conditioning.

I mix one scoop and put in a small glass of water to drink just before heading out on my road bike for a 2+ hour ride. I first make a paste with a very small amount of water, then add about four more ounces of water and stir. I don't like making a solution to use on rides because of the difficulty of cleaning the container. It just doesn't dissolve all the way and it leaves a residue. But the solution helps give me good energy for my rides. The 32 servings become 64 servings (or rides) for me.

Perpetuem is my go to liquid fuel for any activities that run from 2.5hrs to all day (anything shorter and I'll use Hammer's Heed product). It simply works and has a noticeable (positive) impact on performance & fatigue on long rides, hikes, paddles, etc. Flavors are just ok and the powder is a little sticky, but absolutely improved performance for extended activities.
