Energy gels made with real lychee, mango, and white peach.
Three launch flavors. Pick the one you want first — we'll make more of whatever wins.
Real lychee, mango, and white peach concentrate. Not "natural tropical flavor," which is whatever a lab made this week.
Under 10 ingredients. Nothing you can't pronounce. 25g carbs, dual-carb blend, absorbs fast so your stomach stays happy.
A real gel, not a syrup. No sticky burn, no chemical aftertaste, no gluing your teeth shut when you need it most.
$5 deposit. We're making ~3,000 units per flavor for the first run. Your deposit locks your spot, your flavor, and first-ship priority. Applies to your first order — or we refund in full.
Your reservation is locked. Confirmation email incoming. We'll send monthly updates until we ship. Now go run.
Our target ship window is Q3 2026. Making an energy gel from scratch takes time — getting the recipe right, working with our manufacturer, making sure it stays fresh for a year, then the first production run. We'll email you monthly with real updates. If we're late, we're late honestly.
Because "free email signup" tells us nothing. $5 is enough to make you think about it — and enough to tell us we're building the right product. If you're not willing to put down $5, we shouldn't be building this.
Most gels: chocolate, vanilla, fake tropical, sticky texture, too sweet. Kai Fuel: real Asian fruit concentrates, under 10 ingredients, a smooth gel texture (not syrup, not goop), 25g carbs that absorb fast, zero chemical aftertaste. Every stat matches or beats the Asian-brand competition.
Luke Chen — runner in Atlanta, half marathon training, engineer by day. Got tired of every gel on the market tasting the same three flavors. 开 (kāi) means "open" or "unlock" in Chinese. It's what a good gel should do — unlock the next mile.
Yes. Your flavor choice here helps us plan production. You'll get an email confirming your final flavor breakdown before we ship.
Full refund, no return required. Keep the gels, give them to a running buddy, throw them in your race bag. I only want this in the hands of people who actually want to keep buying it.
