Cortisol is not just the stress hormone. Now measure yours.
A lab test you do at home, shipped to your door — your cortisol rhythm across one full day, interpreted one-to-one by a neuroscientist.
Cortisol Rhythm Panel
- Your cortisol rhythm: 4 saliva samples across one day — how your stress axis moves from morning to night
- Plus the full urine neurotransmitter profile: serotonin, dopamine, noradrenaline, adrenaline, GABA, glutamate
- Kit shipped to your home, prepaid return to the lab
- Results session with Francisco (neuroscientist) included
The price includes the test kit, lab analysis, shipping within Portugal/EU, and the results session. VAT exempt: clinical psychology service (art. 9(1) of the Portuguese VAT Code). Lab analysis by Doctor’s Data (LC-MS/MS), ordered by MuLabs as registered practitioner via Nordic Laboratories.
A complete collection kit, nothing to figure out
The Nordic Laboratories kit comes with everything: collection tubes, step-by-step instructions, and the prepaid return packaging for the lab. You collect at home, in your own time.

Results, explained
A one-to-one session with Francisco: your numbers, what they mean, what to do next — integrated with your qEEG if you have one.
What the test actually tells you
A rhythm, not a single number. Cortisol is supposed to move: higher in the first hour after waking, falling through the day, low at night. A single measurement can’t see that — four time-points across one day can.
More than stress. Cortisol is also your body’s wake-up and energy signal — the same axis touches sleep, focus and recovery.
The context (neurotransmitters). The same kit measures serotonin, dopamine, GABA, glutamate and the adrenaline family — so you see whether the stress axis and the messenger systems tell the same story.
And what it is not. This is a body-level snapshot, not a brain scan. The brain’s live activity is what a qEEG shows — the two together are where it gets interesting.
Honest questions, honest answers
Why saliva, and why 4 times?
Saliva tracks the free, active fraction of cortisol, and it’s easy enough to collect that you can repeat it 4 times in one normal day — which is the whole point. The rhythm is the signal: when it rises, when it falls, where it should be low. A single value, measured once, tells you very little.
Who is this for?
People who want data behind how they feel: wired but tired, slow mornings and wide-awake nights, energy that crashes mid-afternoon, stress that never switches off. It’s also a natural next step after a MuLabs qEEG assessment.
Which lab runs it?
Doctor’s Data, a specialist clinical laboratory, using LC-MS/MS (mass spectrometry). These tests are practitioner-only — MuLabs orders them for you as a registered practitioner through Nordic Laboratories.
I take supplements or medication — can I still test?
Usually yes — tell us what you take when you order and we’ll tell you what to pause (some supplements) and what never to touch (prescribed medication — never change it for a test). The results session takes everything you take into account.
How long until I know something?
Kit at your door within days; about 2–3 weeks of lab time after your samples arrive; then your results session is booked at your convenience.
This test is for wellness insight and self-knowledge. It is not a medical diagnosis and does not replace your doctor.
