How it works
What's inside, and what each part does.
01
Fuel
5g
of real cane sugar. That's it.
Most energy drinks have 37 to 54 grams.
That's a lot of sugar all at once.
5 grams gives you quick, real energy without the big sugar spike.
The rest of the sweet taste comes from plants:
Reb MMonk fruit
Plus organic agave fiber, a prebiotic that feeds the good bacteria in your gut.
02
Lift
187mg
of caffeine from green tea leaves.
Caffeine gives you the lift.
L-theanine helps smooth it out, so you get the energy without the jitters.
The result: a smooth curve, not a jittery spike.
03
Focus
Alpha GPC gives your brain choline.
Your brain uses choline to make acetylcholine, the messenger behind focus and memory.
Ginkgo supports blood flow to your brain.
Ginseng helps you stay sharp when you're running low.

04
Power
B vitamins help your body turn food into energy.
We use methylcobalamin for B12 and P5P for B6.
Cyanocobalamin has to be broken down before your body can use it.
Methylcobalamin is ready to go.
05
Deliver
Electrolytes are minerals: sodium, potassium and magnesium.
Sodium and sugar team up to pull water into your body faster.
That water carries the caffeine and every active in with it.
So you feel it sooner and stay hydrated while you do.

Clean
No artificial flavors, sweeteners, colors or preservatives.
No sucralose. No sorbate or benzoate.
Just plant fiber from agave and a clean, bright taste.
The sugar math
Just enough. Not a sugar bomb.
Sugar isn't the enemy. Too much of it is. A classic energy drink packs 37 to 54 grams, which hits your bloodstream fast and can leave you lower than where you started.
Zero-sugar drinks swing the other way and lean on sucralose. We landed in the middle: 5 grams of real cane sugar, about 20 calories, that your body can use for energy right away. Small enough to skip the big spike. Reb M and monk fruit handle the rest of the sweetness.

Questions
Straight answers
How much caffeine is in a can?
187mg, all of it from green tea. For reference, a 12 fl oz Red Bull has 114mg and a Celsius has 200mg. The FDA cites 400mg a day as an amount not generally associated with negative effects for most healthy adults.
Why use sugar instead of going zero sugar?
Because a little real sugar is real energy your body can use. Zero-sugar drinks get their sweetness from sucralose or other sweeteners. We use 5g of cane sugar, about 20 calories, and let Reb M and monk fruit carry the rest.
What is methylcobalamin?
Methylcobalamin is the natural form of vitamin B12. Most energy drinks use cyanocobalamin, which has to be broken down before your body can use it. We do the same with B6: P5P instead of pyridoxine HCl.
Is there anything artificial in it?
No. No artificial flavors, sweeteners, colors or preservatives. The can stays shelf stable with malic acid instead of sorbate or benzoate.
Who shouldn't drink Instant Kill?
It contains caffeine, so it's not recommended for children, people who are pregnant or nursing, or anyone sensitive to caffeine.
Where can I get it?
Order the 12-pack on Amazon, or use the store locator to find a cooler near you.
