Prologue โ The wall
Different walls. Same problem.
It's rarely talent that fades in the final hour. It's fuel. You carry only so much fast energy, and your brain โ the most demanding organ you own โ burns through it whether you're climbing a mountain or a spreadsheet.
When the easy fuel runs short, everything you're good at gets harder. That's not a willpower problem. It's a fuel problem. And fuel problems have fuel solutions.
Chapter I
You were born with a backup generator.
When fast fuel runs low โ a long fast, a low-carb stretch, a long day in the mountains โ your liver starts making ketones: an energy source your brain and muscles are built to burn. It's how humans hunted, foraged and endured long before anyone invented an energy gel. Ketone-IQ lets you switch it on without the fast.
The fast fuel.
The reserve fuel.
Tank two, on demand. No fasting. No keto. No sugar.
Scroll the clock forward. Here's what happens after you twist the cap โ and why it feels different from a sugar hit.
Illustrative, not measured data. Individual response varies with dose, activity and diet.
Two ounces, zero sugar. The active ingredient is R-1,3-butanediol โ a ketone precursor your body already knows exactly what to do with.
It converts the precursor into BHB (beta-hydroxybutyrate) โ the same ketone your body makes on its own when it's been running long.
BHB enters your bloodstream, ready for brain and muscle to burn alongside glucose. That's why the pros take it 30โ60 minutes before the hard part.
Ketones stay elevated for hours โ a second fuel running next to your carbs. No sugar spike. No sugar crash. Just more in the tank for the second half.

Chapter II
First built for people who don't get a second attempt.
Most energy products are built for a flavor trend. Ketone-IQ was built for a brief: give elite operators a fuel that keeps the body and the brain sharp when the mission runs long. Then the world's best cyclists got hold of it. Now it's in your hands.
Two Stanford alumni found H.V.M.N. โ Health Via Modern Nutrition โ to chase human performance with real evidence.
They launch the world's first drinkable ketone, and go straight back to the lab to make it better.
A U.S. Department of Defense contract funds a next-generation fuel for elite special operators.
Ketone-IQ arrives: re-engineered to taste better, cost less, and keep ketones elevated longer.

Your desk. Your long run. Your 5 a.m. Same fuel, no special clearance required.
Three hard hours. Three ways to fuel them. Tap one and we'll set up your order.
10g of ketones for the third hour of focus โ without stacking another coffee on top of the first two.
30โ60 minutes before the long ride or run. Keep your carbs in the plan โ and add a second fuel to it.
5g of ketones plus 100mg of natural caffeine from green tea. Your morning coffee, with a second engine.
Chapter III
What happens when the fuel shows up.
Your brain is about 2% of your body and burns roughly 20% of your energy. It's built to run on ketones โ during long fasts, they can cover most of its fuel needs. Ketone-IQ hands it that fuel without a sugar spike, for the block of work that matters.*
In long efforts, ketones are an extra source of energy that runs alongside carbohydrate. The pros don't swap their gels for ketones โ they stack them. Think of Ketone-IQ as more fuel in the plan, not a replacement for it.*
Ketones aren't a stimulant, so the No Caffeine shot won't feel like an energy drink. What people tend to notice is quieter: the second half feels more like the first. Want a kick, too? That's exactly what +Caffeine is for.

Straight answers. No lab coat required.
The active ingredient is R-1,3-butanediol, a ketone precursor your liver converts into BHB (beta-hydroxybutyrate) โ a ketone your brain and muscles can use for energy. Zero sugar in either formula. +Caffeine adds 100mg of natural caffeine from green tea and carries 5g of ketones; No Caffeine carries 10g.
No. That's the point. Ketone-IQ raises circulating ketones without fasting or cutting carbs. It's a temporary boost in available fuel โ not the same as the full metabolic state of a long fast, and it works alongside a normal diet.
No Caffeine: no. There's no stimulant, so there's no jolt โ people describe it as steadier, not louder. +Caffeine: you'll feel the 100mg of caffeine, about a cup of coffee's worth. Experience varies by person.
No. Treat ketones as an additional fuel source, not a substitute for carbohydrates, fluids and electrolytes. Stack it into a fueling plan you've already practiced.
About 30โ60 minutes before training, or roughly 30 minutes before a focused work or study block. Follow label directions, start with one shot, and test it in training before you ever try it on race day.
If you're unsure, start with No Caffeine โ twice the ketones and no stimulant to coordinate with your coffee. Choose +Caffeine when you want the 100mg kick built in. Or grab the Two-Fuel Starter and find out for yourself.
