Two Hydrafuel and two Creatine Monohydrate. Hydrafuel replaces the salt and the fuel you burn through while you train. Creatine builds the strength you come back with. Together they cover the session and the weeks after it, and buying them as a stack saves you $20.
2 × Hydrafuel, 1kg each. 27 serves per bag. 30g dual-pathway carbs and 530mg sodium per serve.
2 × Creatine Monohydrate, 500g each. 100 serves per bag. 5g of pure monohydrate, one ingredient.
Hydrafuel: one scoop in 500 to 750ml, sipped through any session over an hour.
Creatine: 5g a day in anything wet. Timing does not matter, consistency does.
They mix together fine in the same bottle if that is easier.

What's in the box
Two jobs. One box.
Hydrafuel works during the session. Creatine works across the weeks. Most people end up buying both anyway, so this is the cheaper way to get there.

Why these two
The session and the weeks after it.
Most stacks are a discount looking for a reason. These two work on different timescales, which is exactly why they belong together.
02
Strength that compounds.
5g of creatine a day adds 5 to 15% to strength and power output over a block. It pays off in week four, then month six, then year two.
03
One habit covers both.
Creatine in the morning, Hydrafuel in the bottle. Two scoops a day and the whole training week is covered.
Why we made it
"They told me I'd never run again. So I did.
KYRO is what that journey built,
because I ran."
Two ACL tears and a year I almost lost. I built KYRO between recovery and the Ironman 70.3 World champs start line. For everyone making their own version of that journey.

FAQ
The questions worth asking.
Yes. Creatine has no taste and dissolves into Hydrafuel without changing it. One bottle, both jobs.
254 serves in the box. Two Creatine bags cover roughly six months at 5g a day. Two Hydrafuel bags cover 54 sessions, so around three months if you are training long three or four times a week.
Yes. Creatine saturates your muscle stores across weeks rather than hours, so the daily 5g matters more than the timing. Hydrafuel is for the sessions that run long.
Both are sold on their own. The stack exists because most people end up with both anyway, and this way it costs $20 less.

Pairs well with the work.
