Ultra High Carb
For pro-level performance. PFF contains four different carbohydrate sources (maltodextrin, fructose, glucose, and sucrose) to allow your body to absorb and convert energy more efficiently than a single carbohydrate source. 

Curious if this mix is right for you? Chat with an INFINIT Formulation Specialist to determine the right strategy for your goals.

Fructose for Max Absorption
It’s all in the gut. PFF includes a four carb blend (maltodextrin, glucose, fructose and sucrose) and features a 2:1 glucose to fructose ratio for increased caloric absorption. Fructose is digested via a completely different pathway in the gut than glucose. Adding fructose increases your gut’s saturation point for processing carbs, allowing you to digest and absorb nearly 50% more carbohydrates than using a single source approach. This particular glucose-to-fructose ratio has been well studied over the last decade and has shown to be the key to success for high carb fueling methods.

INFINIT Electrolyte Blend
Containing naturally sourced sea salt, potassium, magnesium, and calcium. This blend of essential salts helps to eliminate muscle cramping by rehydrating the body efficiently and replenishing the minerals lost through sweat. No need to carry salt tablets or extra electrolytes — everything you need is right in your bottle.

All Natural Ingredients
Made with 100% all-natural ingredients with zero artificial flavors, sweeteners, or colors. It tastes great, even warm, and will not sour in the heat. Naturally flavored with real fruit extracts, and sweetened with natural cane sugar and fructose.

This Stuff is Legit!
Apr 30, 2024
I just wanted to give the 120 GRAM PREMIUM FRUCTOSE FUEL a review. I used it for BWR Wafer in California this past weekend. This nutrition was absolutely perfect. I had a little over 120 gram of this stuff per hour for the entire 5:05 of the race. I did not have any other type of nutrition during the race. I had zero stomach issues, no nausea, no cramping, zero crashes in energy. I will personally bring using this for every race going forward including unbound 200. Well done, Infinit Nutrition! This stuff is legit!!

The science is real
Apr 26, 2024
I tried the Premium Fructose Fuel to see if the high carb hype was real. It is! I feel so much stronger in races and I’m hitting the podium more often. I especially like the 500 electrolyte level with caffeine.

The 120g is a GAME CHANGER. I have been struggling with nutrition for several years and feel like I've finally hit my stride. Have a 12 hour mountain bike race coming up and this is my cheat code.

The 90 gram Fructose Premium ...
Jan 2, 2024
The 90 gram Fructose Premium Fuel is my favorite. I’ve been using for training and racing and love it. 2 scoops provide 357 calories good enough for about an hour. I highly recommend it.

Using Infinit PREMIUM Fructose Fuel provides a positive difference...
Dec 14, 2023
This is my second go-round with Infinit PREMIUM Fructose Fuel. This past summer I used the 90g/500mg mix that worked well for a number of rides both indoors and outdoors (between 20-100 miles). Now I'm using the 120g/500 mix which is helping boost my energy during my rides.

I LOVE THIS! My coach has been trying to get me to get in more carbs per hour and this is really helping. It's sweet and I sweat a lot so I add a touch of salt to the blend even at 600mg and it is perfect. I am currently using the 90g version.

120g Carb mixed with 500mL ...
Sep 22, 2023
120g Carb mixed with 500mL flask is how I have used this so far. I was pacing 100K of my friends 200 miles. I was excited knowing I was getting more calories and carbs over my Custom Blend I was already using. I didnt have any trouble keeping a steady stream of this in my belly every 20min. I will keep using this towards my own 100 mile race in October.

Product Questions

can we make the super premium fructose mix with lighter flavor
Question by: Matt Thompson on Sep 22, 2023, 6:10 PM
Hi Matt,
Thanks for your question. Unfortunately the flavor level of the Premium Fructose Fuel is locked in and not customizable. If you are looking for a lighter flavor and/or less sweet drink, we would recommend our traditional custom blend system which can still go up to 81 grams of carbohydrate per serving: Let us know if you have any other questions or need any help with a blend. Thanks!

For years I've double concentrated my custom blend for Ironman racing, so I don't have to figure out how to carry 5 bottles. Will this blend mix well double concentrated? I'd still plan to take in quite a bit of plain water in addition to the concentrated mix.
Question by: Nicholas Modrzejewski on Apr 13, 2024, 8:33 PM
Hi Nicholas,
Yes the Premium Fructose Fuel mixes very well and can be double concentrated. The only thing to note is that Fructose Fuel is already sweet so double concentrating it will only make the taste even sweeter. For some, this sweetness level may be overpowering but washing it down with plain water should also help. Feel free to reach out with any questions or to discuss this further.
