The difference
Most functional drinks hide the dose.
A proprietary blend hides how little active you're getting. We print every milligram, and only claim what's permitted.
The ritual
Chill, crack, drink
No prep, no mixing. Keep it cold, crack it open whenever you need it.
Keep it chilled
Best served cold, straight from the fridge.
Crack it open
Ready to drink - nothing to mix, nothing to wait for.
Get going
Your functional cold brew, wherever the day takes you.
What's inside
The whole formula. On the label.
Every ingredient at the dose it’s actually in. Items tagged Approved claim carry an authorised health benefit, in the approved words; the rest are listed in full and described in plain terms.
The evidence
Doses you can check
Most blends sprinkle a token amount and hope you don’t notice. We print every dose in full and put the number on the front - so you can check it against the research yourself.
Natural caffeine
A measured 120mg - in a real cold brew, not a synthetic energy drink.
L-Taurine
A full gram of taurine, printed on the can.
L-Tyrosine
The amino people reach for under load - 500mg, listed in full.
Magnesium · 15% NRV
Contributes to normal muscle function and the reduction of tiredness and fatigue.
The real thing
Named and dosed, nothing hidden
Every active named, every dose on the can - not a mystery “energy blend” you can’t measure.
From the cold brew itself - a measured amount, paired with taurine and tyrosine.
Built into the brew, at doses you can see on the can.
Why these, at these doses

Why we made it
I was tired of paying for functional drinks that wouldn't show their working. So we built the one I wanted - full doses, on the label, nothing to hide.
Honestly
Is this for you?
We'd rather you bought the right thing. Here's the honest version.
It's for you if…
- You read the label before you buy
- You train or push through long days
- You don't want an energy crash after a 200mg caffeine bomb
- You like clean electrolytes built in
- You want it ready to drink, no mixing
Probably not if…
- You want zero caffeine - try Focus Smart Stick instead
- You want a sweet, sugar-filled drink
- You just want a run-of-the-mill pre-workout
- You don't take the right supplements at the right time

Questions
Good to know
The sticks are formulated to be flavourless, so they dissolve into water, coffee or tea without changing the taste. The cans are a proper cold brew you drink as-is.
Check the formula above — where caffeine is present it’s listed with its dose. Focus and Recover are caffeine-free; Perform and the cold brews contain caffeine.
Yes. Where a benefit is an authorised health claim, we use it in the approved words - those are the items tagged Approved claim. For the rest, including caffeine, we state the dose and what the ingredient is known for, and leave you to check. We don’t dress up a benefit we can’t stand behind.
