Strengths:    Has proper nutrition for long distance events, like a liquid food

Weaknesses:    taste

Bottom Line:   
Ok, in full disclosure, I'm a road biker but I've got LOTS of experience with this product. I use it on centuries and long training rides. I mix 2 scoops with 24 oz. of water in my Polar bottles. To help the taste I add a couple packets of Stevia sweetener per bottle. My bike is set up with 5 cages so 4 of my bottles have Perpetuem while the other has ice water. I drink half a bottle every 11 miles and that gets me to 88 miles, from there on it's all me. I also use e-gel (great stuff!!), and down one of those every hour. I've done centuries without taking on food at rest stops in cooler weather, only topping off a couple bottles with water at the mid-way rest stop and I've never felt hungry. I've used the Orange-vanilla Perpetuem but am going to try the new strawberry flavor some shops sell it in small packets so you can give it a try without shelling out a lot for the big jug.

Strengths:    This is one of the few drinks which contain protein and fat. It has similarities in that respect to Ensure. It is designed for multi-hour endurance efforts; situations where you will truly run out of carbs, not just get tired.

Weaknesses:    Taste.

Bottom Line:   
This is my long day staple. If I am going to be out for several hours on MTB, road, trail running, AR, etc. then Perpeteum is my fuel of choice usually mixed with a bit of EFS and green tea for caffeine and antioxidants. It is far from a complete meal, but it is much better than straight carbs. It doesn't give me stomach problems any more than any other product would. I mix it into a thick paste and chase with appropriate amounts of water for a long course (Iron distance) race; the new solids may be a better choice than the paste mix.

Strengths:    Before I started to use Perpetuem I had problems with bonking and I also had muscle fasciculations after the ride. Bonking is no longer and issue and I even use it for shorter events as it prevents the fasciculations. I use of for cross country skiing and cycling. I like the ability to calculate the concentration that you will need for an event.

Weaknesses:    Hard to dissolve but I just shake it up before I drink it. I find the taste quite tolerable. It can be hard to find in stores.

Bottom Line:   
Prevents bonking. I was happily surprised that it also prevented muscle fasciculations.

Strengths:    Caloric balance between fats, protein and carbs.

Weaknesses:    No electrolytes

Bottom Line:   
Even though my reason for trying this stuff was to use on the mountain bike, the first test was on the road where I could could control intake easier and could make adjustments without too much trouble if things fell apart. Things didn’t fall apart and honestly, I felt great through out the ride. I tested the product on a 5 hour mtb ride and again had no troubles. Time for the real deal. I debuted the use of Perpetuem at the 12 Hours of Arcata in late 2009. I drank a 1-hour bottle each lap and overall I was very pleased with the result. I drank no additional water or other products. aside from the 1-hour bottle each lap. I didn’t have any gastro problems and I felt full and fueled for the first six hours. The only problem I had was over hydrating. This was not a problem with the product, just the fact that I was mixing it in with too much water. The result was a fair amount of cramping and a sloshy gut. So, I didn’t drink anything for two laps until I felt better. After 8 hours I started getting tired of the taste so I mixed things up a bit and starting drinking HEED and eating a bar on each lap. Therefore, as a sole source of calories it fell short. Again, I think that was due more to my tastes and inexperience with it than the product itself. I had a nice even energy burn for the entire race and although was getting tired I never felt like I was bonking or running out of gas. Keep in mind there is some caffeine in there and I can definitely feel it after a race. As exhausted as I am I always have a hard time falling asleep when I drink Perpetuem.

Strengths:    Most people reviewing find it to work great

Weaknesses:    I'm throwing my review out there in case anyone else is like me and finds this product doesn't work for them. This stuff tastes really bad and it gets worse as it warms up. Everytime I've tried to use it in long distance races(4+ hrs) I have to stop drinking it after the first hour if it gets to warm. To make matters worse, when it warms up it starts to make me nauseous and sick feeling in my stomach.

Bottom Line:   
In theory and for most people this product works great despite the terrible taste. However, I've used it in three races and found it does not work for me once the flavor gets even worse as it warms up. Everyone has their own formula for what works, but for me this stuff doesn't even come close.

Strengths:    Keeps me from having hallucinations of ham sandwiches crossing the trail in front of you on long rides.

Weaknesses:    no

Bottom Line:   
In the future i will make sure my riding buddies are using this stuff too so that I won't be cutting rides short. People tend to start whining that they are hungry 3 hours into a good ride when I feel fine and want to go more using Perpetuem. Just sayin. It works.

Strengths:    It works and it works extremely well.

Weaknesses:    The taste is reminiscent of soy milk. Not bad but it is there. The Orange-Vanilla is even more subtle.

Bottom Line:   
When I first started to take up century rides I was ill prepared for the nutritional needs they require. My first couple of centuries I bonked around the 80-90 mile mark. After that I started searching around and comparing what was out there. I tried a few different things starting with cliff bars and a few energy drinks here and there. I asked around at the forums here and at roadbikereview.com and Hammer products where highly, highly, recommended. On my next century I had some Hammer Gels and Perpetuem. I did not bonk....finally. I also hadn't done more than maybe a month, month and half, of riding between my last century when I bonked and this one when I didn't.

I was tired at the end. I felt fatigue. I knew I had worked out. There was no sudden burst of energy or any feeling of additional energy. I was simply able to keep riding, turning the pedals to the end with a fairly consistant effort. And it is this that I think is what makes Hammer products so great. They don't add to the effort. They don't make things better, faster, and stronger Rather, they give the fuel your body needs and as long as you're willing to put in the effort, you'll achieve what you set out to do. Simply put, in order to actually get better, faster, and stronger, you need to put in the time, miles, and effort. This allows you to do that if you're so inclined.

Strengths:    It works. Keeps me going strong after a long strenuous workout/race. Great buffers for the lactic acid, and my stomach never feels stressed.

Weaknesses:    none so far

Bottom Line:   
Best product for long rides available. Usually mix it with Heed, and am good for a few hours of hard riding. I recently did an eight hour ride in Durango Colorado, ride was supposed to be only four hours, but, at the end of eight hours, I just took my last gulp of Heed/Perpetuem, and felt great. My legs were fatigued, but, were still going strong. The lactic acid buffers work great. Nothing on the market compares to this product. Good job Hammer.

Strengths:    Works as advertised, keeps up energy, prevents soreness

Weaknesses:    Tastes like poo. Seriously. Like poo.

Bottom Line:   
Tastes pretty foul once it warms up. It ain't all that great when it's cold, either. But it does work -- I rode Hidden Valley, Moab Rim and Slick Rock in a single day using Perpetuem, HEED, Gu packs and water, and I felt fine the next morning. That's pretty amazing.

Strengths:    IT WORKS, flavor isn't overpowering

Weaknesses:    Not as readily available as other brands, could mix a bit better

Bottom Line:   
THIS STUFF WORKS. It's not my favorite tasting drink, but that isn't to say it tastes bad. I have used it on rides ranging from 10-300+ miles and it has worked well for all of them. The only times I have had any problems with Perpetuem has been on really hot days, but that's only been a couple of incidents where nothing went down well...A great product, especially on rides lasting longer than 2 hours.

Strengths:    This stuff works.

Weaknesses:    Tastes sort of like orange/vanilla pancake mix. It doesn't desolve easily.

Bottom Line:   
This stuff works well. I rode a very hard race with over 4,500 feet of climbing in 25 miles and I never felt out of energy. This is a very good product. Based on the fact that it works well (and I never got sick due to it) I rate it very highly.

Works okay. I can't say it wows me or works as good or better than Endurox R4--before they dropped the glucose and lost me as a user. It does work better stopping the bonk than not using it.

Strengths:    Perpetuem does it all and keeps you well fueled out there. I practically live on this stuff and have used it at endurance events in combination with Hammer Gel and other products for over 28 hrs without getting sick of it. Plus the taste is just right for me, where other products can be so heavy or chalky.

Weaknesses:    None for me. I can't promise it will be as good for you but I do think everyone should try it. Put two scoops in you water bottle filled with ice and add water. shake and enjoy.

Bottom Line:   
Best fuel on the market.
