Synergy Overview
Energy & Performance: Cluster Dextrin provides sustained energy while dextrose delivers rapid glucose uptake. Together, they cover both immediate and extended exercise demands.
ATP Resynthesis & Recovery: Ribose accelerates nucleotide and ATP regeneration, working alongside dextrose for glycogen restoration and glycine for mitochondrial support.
Glucose Metabolism & Insulin Sensitivity: Myo-inositol improves glucose handling and insulin efficiency, complementing the carbohydrate blend and supporting stable energy release.
Antioxidant & Cellular Defense: Glycine contributes to glutathione synthesis, buffering oxidative stress from high carbohydrate metabolism and synergizing with ribose’s nucleotide support.
Holistic Cellular Energy: All five ingredients converge on energy metabolism pathways, ensuring that glucose is efficiently absorbed, stored, and recycled into ATP for sustained performance and faster recovery.
FAQ
Q: What’s the main difference between the two formulas?
A: The new CARB FUEL (formerly HEXAGEN) takes everything that worked in HEXAGEN and pushes it further. It delivers faster energy delivery, deeper cellular recovery, and a more complete glycogen reload thanks to higher carb density and a stronger ribose backbone.
While HEXAGEN focused on balanced endurance, CARB FUEL is engineered for performance acceleration — built for athletes who want to recover faster, train harder, and repeat sooner.
Q: Why combine cluster dextrin and dextrose in CARB FUEL?
A: The 1:1 ratio of cluster dextrin and dextrose creates a dual-speed fueling system that HEXAGEN never reached.
- Cluster dextrin delivers smooth, stomach-friendly glucose that keeps energy stable.
- Dextrose provides the rapid insulin response needed for post-training nutrient drive.
Together, they hit both the immediate and sustained energy windows — meaning faster glycogen restoration and less downtime between sessions.
Q: Why does CARB FUEL include ribose, and how is it different from HEXAGEN?
A: Both formulas have 10 g of ribose, the sugar that drives ATP regeneration.
The difference? CARB FUEL pairs ribose with fast carbs, glycine, and inositol, creating an optimized environment for rapid cellular uptake and energy restoration. This means your muscles recover faster, feel fuller, and are ready for the next training session sooner, compared to HEXAGEN’s slower, less targeted delivery.
Q: What’s the purpose of adding glycine to CARB FUEL?
A: 3 grams of glycine enhance insulin efficiency and protect against oxidative stress during recovery. It helps shuttle glucose and ribose into the cell while supporting glutathione production — your body’s primary antioxidant defense.
CARB FUEL therefore absorbs faster, recovers cleaner, and supports better hormonal balance post-training.
Q: Why include inositol in CARB FUEL?
A: 2 grams of inositol fine-tune how your cells respond to insulin and manage glucose. It’s a quiet performance amplifier: you feel smoother energy uptake, steadier blood sugar, and sharper nutrient partitioning.
While HEXAGEN relied on mineral salts and ornithine for balance, CARB FUEL upgrades the metabolic control system itself — right at the receptor level.
Q: How does CARB FUEL perform compared to HEXAGEN?
A: HEXAGEN provided reliable, steady energy — but CARB FUEL amps things up. The higher carb turnover and precision co-factors (ribose, glycine, inositol) create a noticeable surge in muscle fullness, faster recovery, and a stronger “second wind” effect post-workout.
Athletes switching from HEXAGEN typically report quicker refueling, fewer energy crashes, and a tighter, more anabolic response after training.
Q: Who should use CARB FUEL?
A: Anyone training for intensity, strength, or volume. CARB FUEL was built for athletes who push into glycolytic fatigue — lifters, sprinters, CrossFit, or team sports.
If you loved HEXAGEN’s balance but want to feel a real performance edge, CARB FUEL is the clear evolution.
Q: Why choose CARB FUEL over a pure cluster dextrin product?
A: Pure cluster dextrin is great for steady energy, but it only addresses one part of the recovery equation. CARB FUEL combines cluster dextrin + dextrose for both rapid and sustained glycogen replenishment, plus ribose, glycine, and inositol to accelerate ATP synthesis, improve nutrient uptake, and reduce fatigue.
In short: CARB FUEL doesn’t just fuel your muscles — it recovers, repairs, and primes them for the next session, something pure cluster dextrin alone can’t do.
Q: Why choose Formula 1 over a sports drink like Gatorade?
A: Sports drinks are primarily sugar and electrolytes — they hydrate and give a quick energy spike, but they don’t actively rebuild cellular energy or optimize recovery. CARB FUEL delivers:
- Rapid and sustained glycogen restoration
- Targeted ATP support via ribose
- Enhanced nutrient uptake with glycine and inositol
This means faster recovery, fuller muscles, and less downtime after training — benefits you simply won’t get from a standard sports drink.
