Product Description

FAST-ACTING FUEL - Karbolyn is a CARBOHYDRATE powder derived from potato, rice, and corn that has been clinically studied (with peer-reviewed, published research). The use of this type of energy and recovery supplement is designed for elite athletes who want to load their muscles with energy quickly and easily. Karbolyn allows you to carb load in minutes, not hours, before your event or training session.
I WILL ACCEPT NO SUBSTITUTES - There's nothing like Karbolyn to power your monstrous workouts! Although it enters the bloodstream like a simple sugar, the energy it provides lasts longer without crashing. There can be no comparison between Karbolyn and carbohydrate products sold on the market, either simple or complex, since Karbolyn absorbs faster than dextrose, sugar, bread, pasta, rice, and other carbohydrate products. This is why professionals around the world use it!
Do you want to outlast, outmuscle, and outperform anything and everything in your path? DO YOU WANT PUMPS, POWER, AND PEAK PERFORMANCE? If you don't want our lab to test overhyped copycat products, then you should stop fooling around with them. The Karbolyn Pre, Intra, and Post Training stimulates and maintains a high-intensity training level, maximizing the power output for greater muscle hardness and fullness... and pumps you've never had
SPORTS DRINK - Skip those sugar-filled "sports" drinks that will do little to help you during your workout or game. Featuring zero sugar, no gluten, no stimulants, and zero dairy, Karbolyn is also vegan friendly. Have you ever used a carb powder that clumps like cement or gels? Many people are surprised at how easily Karbolyn mixes and how delicious the taste is. Essentially, Karbolyn ensures you maximize glycogen storage before, during, and after training... so you don't feel bloated, lethargic, or cramped!
It is hard to find brands that actually manufacture their own products other than EFX Sports, which is now part of a very small, elite group. Karbolyn meets our proprietary claims, is 100% banned-substance free (informed sport certified), and always delivers what is promised on the label. If you purchase Karbolyn by EFX Sports, you get the purest, most powerful carbohydrate product on the market!

I agree! A representative from the company told me that it has a similar composition to rice, potatoes, The use of animal derivatives is not permitted.

Can anyone tell me if they have tried this before running a long distance? Is that how it worked?

This is something I have attempted in the past at a Spartan Beast of about 12 miles that took about 4 hours to complete in mid-July. I was pleased with the result. strongly suggest consuming a gel pack, depending on the number of miles that you run, during your run. I utilize this product before, during, and after my workouts.

It's gonna be a good day, no? The transition from a 2 to a 3 was difficult
5/5

It was a 2 lb tub of neutral to ensure that I wouldn't be a victim of the poison. So I ordered it in 4 lb for sure. Approximately 4 lbs. My preferred neutral is that I can mix it with my EAA Max watermelon for intra in a way that does not interfere with the taste. Sometimes I mix in a slight amount of the powder with my coffee or I have tried it in everything I've tried so far, and it hasn't changed the taste in any way. Among the reasons I love Karbolyn is that I do not experience bloating or upset stomach, and I do not experience the insulin spike or crash after a workout like I do with other pre-workouts. As part of my pre-treatment I take a stimulant During our workout together, I would raise my heart rate to 230-240 This is the 3pm wall, and it's hard, but I no longer notice it. experience steady energy during an intense workout, and I notice I'm recovering quicker than when I'm less intense. My recovery time has decreased significantly after taking carbs. I used to take EAAs and BCAAs, but I can tell the carbs are delivering nutrients to my muscles more efficiently because I saw a difference as soon as I started taking them. The results are pretty darn good, all things considered.

An excellent replacement for a large breakfast before going to Despite being able to complete my workouts in the morning with a lot of carbs, I was still eating a lot of carbs every morning
5/5

The number should be 2 instead of 3 In addition to consuming 4 eggs with rice every morning, I now consume 1 cup of oatmeal with fresh fruit and walnuts, along with a scoop of this protein powder with my breakfast, and I am good for my workouts. It really does seem like a steady supply of carbs. This 4lb tub of shampoo has been used nearly all up and I plan to buy more in the future.

Drink it before or during your workout for an excellent carb boost
4/5

My workouts start around five in the morning, depending on how much time I have At 6am, you should be empty stomached. The presence of 50-plus It makes a huge difference in the quality and endurance of my workouts to have 100 grams of carbs in my system before and during a session. I have tried most of the flavors, and have not come across one I disliked. Unlike plain water, it has a thin consistency and is not viscous. Don't worry about the consistency of the shake, it is not thick at all, like a protein shake.
I have no complaints on the product, I think the flavor and quality are excellent. There is only one thing I don't like about the There is no doubt that this is at a premium price point, and I use it every day.

The results I expected were not as good as I had expected
3/5

After a friend shared this with me, I tried it out. As far as I'm concerned, he's what I would call a legitimate amateur bodybuilder, as he has even competed in a few contests. I thought I would try it after working out after seeing him use Because of the serving size (1 scoop), I think the flavor is very potent, so you basically need a half gallon of water in order to dissolve it (which you won't do, you'll use your shaker bottle). My protein powder is combined with Karbolyn, which makes me feel bloated and gross, especially considering I just completed my workout, but I should be feeling great because I just tried something new. Because I drink my protein by itself throughout the day and I feel great, I know it isn't my protein that is giving me this awful feeling. The last time I took it after working out and going to the pool, I felt like a swing ring was inflated in my stomach (I couldn't even suck into it if I tried, and I don't normally need to suck into it). This product may work for some people, and I am not saying it is a bad product, but I was not satisfied with it. Perhaps I will just add a banana to my protein shake from now on.

If you don't have a scooper, 12 cup is normally sufficient
5/5

It works great! I was overwhelmed by how much was in this thing! The scooper had to be disposed of halfway, so I dumped it in a ziploc to find it. A single one didn't exist. Thanks to past tubs of supplements that I keep, I have old ones on hand. one that is exactly half a serving as it says for each serving (1 scoop is equal to 60cc). A little over half a cup on the scale is just shy of 1/4 cup. As an alternative, if you do not have a scooper in the tub, use 1/4 cup or 1/2 cup, based on if you are going for a full 200cal/50carb serving or a half. Is this stuff going to work now? It is usual for me to do 30 minutes Every other day, alternate the bike ride with a rowing machine workout for 50 minutes. We decided to row for 2 hours this morning fasted at first. It was about half a bottle of gatorade we sipped on while we rowed. A weak feeling and a lightheaded feeling filled me. My plan was to down half a serving of this before I made my oatmeal to get some calories in quickly. It worked well. The next eight minutes went smoothly. I did not wolf down my oatmeal or anything like that. The food was casually eaten. Three hours after taking the medication, I feel amazing. Would be interesting to do a 20-minute video Instead of the long workout this morning, we will have a short session tonight of 30 minutes. It is very strong in flavor, but if you are going to sip on it while doing longer distance biking, rowing, or whatever it is you are going to be doing. If you mix these with a decent sized water bottle or two depending on how much water you need, then this stuff is The power of this stuff is pretty strong if you wait until postworkout and try to take it down. All that, and I was trying to down half a serving of cereal this morning as fast as I could. No idea what a full serving would be like. Though, you may have a sweet tooth to die for P PH (Rainbow Candy tastes like the powder from "Fun Dip" if you've tried that before. In this game, you dip a white sugar stick into powder and suck it up. I found it to be very sweet tasting).

It works, but not perfectly
3/5

According to me, the product does what it is supposed to do. In addition, it is important to note that the product did trigger a warning under California Prop 65 due to carcinogenic chemicals/compounds used during manufacturing. It was revealed to me that they had adjusted the serving size to just pass the warning, so that it would not trigger a No matter what your feelings about Prop 65 are, you should know what's in the product. I sent them an email asking for transparency, and they answered. It should tell users what's in it and at what level, just like an Optimum Nutrition program. I emailed them back, but they didn't return it.

It has a great taste, keeps your energy up, and mixes well
5/5

This is the best carb powder I've tried. I am a bodybuilder and ultrarunner, so I use many. For example, I use it to carb up for a stage, to stay carbed during a long run, or even to keep my energy up when I have a stomachache. The product digests well, mixes well, and stays well dissolved even after stacking it with preworkout, electrolytes, BCAAs,.

Cardio should be done fasted then carbs should be consumed quickly afterward
5/5

IF you like doing cardio fasted and carbing up quickly for weights with no upset stomach like dextrose, this is the product for you. I usually don't eat for another hour or two after weight training with almost no hunger and that means no protein shake either. In order to stretch out the servings of Karbolyn, I started mixing in 25% dextrose. Additionally, I don't consume any carbohydrates for the remainder of the day since I am.
