Introducing
ONETHIRD

The breakthrough after three decades of peptide science:
Melatonin-free. Non-sedative. Liberating.

Everyone f*cking sleeps now.
One night23:00 → 07:00
Without With ONETHIRD

A new dawn

Built on peptides instead of sedatives,
ONETHIRD doesn't work like other supplements.

That's why it doesn't fail like them.

40 minutes of sleep a night.

That's 30 nights a year.

There is some good and some bad news.
Why sleep?

Because your day is built the night before

Willpower, endurance, mood and focus are made in REM and deep sleep.

Get both, and the day is yours.

Goal achievement

Willpower

Poor sleep makes you three times as likely to miss your goals.
Willpower is a prefrontal function, not character.

Deep sleep

Endurance

Muscle repair, tissue, immune work. All of it happens while you are in deep sleep.
Same training, more return.

Sleep satisfaction

Mood

Of the ones with bad sleep: 47%. Same question, same survey.

Focus

Two groups. One got 26 minutes of sleep, the other kept working. Reaction time: 34% apart.
Now imagine a whole night.

That was the good news.
Now things go south.

Why nobody sleeps

One hormone ruins all four for you:

23:10
Falling asleep
01:00–06:34
Staying asleep
07:30
Waking up
09:00
Life

Cortisol,
a stress hormone.

Ten thousand years ago it woke you up and kept you alert when in danger.
Too bad it still can't tell the difference between caveman-you getting attacked by a sabre-tooth tiger and today-you in a meeting full of idiots.

23:10
You can't fall asleepLights off. Brain on. Cortisol still running your day.
01:00–06:34
You don't sleep wellCortisol still active. Deep sleep loses. Wake-sleep-hate-cycle.
07:30
You wake up like shitCortisol should get you going in the morning. Yours kept you going all night.
09:00
Your day is fuckedBrain fog. Zero focus. Coffee fixes nothing. You're trapped.

It's not just you.
It's your friends, your colleagues.
Even the person with the perfect evening routine.

Why nothing helps

Symptom management isn't a cure

Every sleep aid on the shelf misses the point.
You cannot calm a nervous system high on cortisol.

Journal all you want.

What everyone tried

Melatonin and its copycats

2,333 new sleep aids in five years. Almost all of them with melatonin.

Problem is, you don't lack melatonin.
Melatonin tells you when. Cortisol decides if.

What everyone tried (for a few days)

Journaling, meditation, etc. etc.

Breathing exercises, cold rooms, no screens before sleep… and then what?

It worked for a few people. They stopped after a week.

What everyone still tries (despite knowing better)

Alcohol, weed, sleeping pills

Sedation flattens exactly the stages you came for: deep sleep and REM.

Feels like you're sleeping, but you're not. You're in a chemical coma.

One scoop of powder in water, 30 minutes before bed. Then go to bed. That's the whole protocol — the same dose, at the same time before sleep, that the clinical work used. Make it a habit for even better mornings.
How does pre-ordering work?Your founding pouch is reserved at €54 instead of €69 — and that price is locked for every order you place after that. Fully refundable any time before it ships.
Why is there no melatonin in it?You're most likely not melatonin-deficient — you're too wired to switch off. Melatonin only tells your body it's night; it can't quiet a nervous system that's still running. ONETHIRD can. And will. Without adding a single hormone.
So, how does ONETHIRD actually work?By removing the reasons you're still awake. The actives work three angles at once: they quiet a nervous system stuck in overdrive, trigger the drop in core temperature your body reads as “time to sleep,” and let your body build its own melatonin instead of borrowing it from a pill. In short: you wind down. The single most important step to a full night of sleep.
Will I feel groggy in the morning?No. Nothing in here sedates you. You're not knocked out — you're asleep. Deep sleeping, dreaming, regenerating. And waking up as yourself. Or better. The morning is the whole point. Tomorrow starts tonight.
When will I notice a difference?Falling asleep: from the first nights. Deep sleep and mornings: give it two to three weeks. That's when most of our users report the needle really starts to move.
What if it doesn't work for me?60 nights to change your mind after delivery. Full refund — keep the pouch. That's how sure we are.

… And finally, what will happen

Sleep isn't sleeping

It's four quadrants that determine how you live your life.
ONETHIRD tackles all four.

1.1  ·  Falling asleep  ·  23:10

Effortlessly.

Stress down.
Nervous system exhales.

Then you sleep.

1.2  ·  Staying asleep  ·  01:20

No ADHD.

Doing one thing.
Not stopping until it's done.

Once you sleep, you sleep.

1.3  ·  Waking up  ·  06:45

F*ck snooze buttons

Your sleep has ended.
You get up feeling like yourself.

Maybe better.

1.4  ·  Being awake  ·  09:00

Your night

Everything that felt heavy yesterday is just a task today.
