You're exhausted.
But you can't
switch off.

Your cortisol stays elevated all day. C-01 measures it, intervenes at 6pm, and rebuilds your cortisol curve.

Your cortisol
never drops.

Nervous system diagram

It should fall by 6pm. In most people under chronic stress, it doesn't. That's why you're wired at midnight. And why nothing you've tried has worked.

The Aequo system has
three layers.

Measurement. Intervention. Behaviour.

Your symptoms as indicator

Evening anxiety. 3am waking. Unrefreshing sleep. Aequo maps where your cortisol curve is breaking down, then tracks it.

Your pattern
Timed intervention

Two modules. Sequenced to the hour your cortisol should be dropping, not when you're already in bed.

Your compounds
Personalised behaviour protocol

The compounds only work if the behaviours support them. C-01 includes a personalised behaviour protocol, built around your schedule.

Your behaviours

A measured system. Not a guess.

Aequo tracks your cortisol-driven sleep pattern through a daily score — ARC. It moves as your system recalibrates.

Dysregulated

Evening cortisol elevated. Sleep onset slow. 3am waking frequent.

Calibrating

Cortisol curve blunting. Sleep onset reducing. Nights more continuous.

Aligned

24-hour regulation stable. Morning alertness restored. System reset.

Every competitor starts at bedtime.
C-01 starts at 6pm.

Not an overnight fix.

Reserve trial spot
DAY 1-7
Evenings feel quieter.
Most people notice it within the first week. Easier to wind down. Mind less active at bedtime.
WEEK 2
Sleep onset improves.
Falling asleep becomes more consistent. The wired-but-tired feeling starts to ease.
WEEK 3
Fewer wake-ups.
Nights become more continuous. Less disruption between midnight and 5am.
WEEK 4
3am waking reduces.
The early morning cortisol spike — the most common pattern — begins to normalise.
WEEK 6
Mornings feel different.
More alert on waking. The system has had time to recalibrate across the full cycle.
ONGOING
A new baseline.
Stable regulation across the day-night cycle. The goal is not dependency — it's a reset.

Eight compounds.
One behavioural protocol.

No ingredient is on this label for marketing. Every compound has a mechanism, a dose, and a role in the protocol arc.

From our first cohort.

"I've tried magnesium and melatonin for two years. The difference is that I'm actually calm by 9pm instead of just suddenly crashing. By week four, the 3am waking had largely stopped."

Marcus H.
Strategy consultant, Munich

"Taking the first module at 6pm felt strange initially. But that's exactly why it works. I'm actually tired by 10:30 instead of wired at midnight."

Tomás K.
Founder, Berlin

"I didn't think the evening habits mattered. They're what made it work."

Why cortisol, and why the evening?
The mechanism behind the two-module protocol and why intervening at 6pm changes what's possible at midnight.
