Know Thy Hormones: How to Map Your Body with the DUTCH Test
There was a stretch of time when my body felt borrowed.
Panic would slam the brakes on an ordinary afternoon. Sleep thinned to a few ragged hours. My skin erupted along the jawline like a bad flashback. Moods shifted without reason: flat, then wired, then flat again.
Every appointment ended the same way: tube of blood, a quick glance at “normal” ranges, a polite smile. You’re fine.
I kept hearing my own internal verdict: something was off with my hormones. The whole cascade that turns cholesterol into cortisol, progesterone, estrogen, and testosterone felt out of rhythm. I didn’t just want to guess which link had slipped - I needed to see the mechanism, to know exactly what wasn’t working. I needed a map.
So I ran a DUTCH test and tracked an entire cycle - not just a snapshot on some random Tuesday morning, but the full rise and fall of my hormones over real days for an entire cycle. Luteal. Follicular. I mailed the dried strips, waited, and opened the report like an x-ray of my month.
There it was. Cortisol waking too soft, spiking too late. Progesterone not pulling its weight when I needed it. Estrogen metabolism drifting into lanes that amplified symptoms. It wasn’t one villain; it was a pattern.
The thing is, we live in a world of second-hand cures. One friend clears her acne with an androgen-suppressing drug; another swears by estrogen-blocking supplements. But those fixes match their chemistry. If they don’t match yours, you’re just medicating a problem you don’t have. Why poison yourself for the wrong target? Without data you’re shooting in the dark.
DUTCH is a map. It keeps you from guessing. It showed me where my body was struggling so I could stop gambling with treatments and start healing for real. That clarity changed the game. I stopped throwing generic fixes at myself. I built targeted protocols, layered them in sequence, and kept score. Panic eased. Sleep returned. Skin calmed. Mood stabilized.
What the DUTCH Test Actually Measures (in human words)
DUTCH = dried urine hormone testing across multiple points in a day (and, if you choose, across a whole cycle). It captures:
Sex hormones: estrogen family, progesterone (as metabolites), and androgens like DHEA and testosterone.
Adrenals: free cortisol and cortisone across the day so you can see rhythm, not just totals.
Metabolites: how you process hormones—hydroxylation and methylation patterns for estrogen; 5-alpha vs 5-beta pathways for androgens.
Extras (panel-dependent): melatonin metabolite, oxidative stress markers, and selected organic acids.
Types / Panels of DUTCH Tests
DUTCH Complete
Sex hormones + adrenal + organic acids + metabolites + oxidative stress + melatonin etc.
DUTCH Plus
Similar to Complete but with extra markers like Cortisol Awakening Response (CAR).
DUTCH Cycle Mapping / Cycle Mapping Plus
Focused on women: tracking hormone fluctuations across the menstrual cycle. Useful for irregular cycles, fertility, unexplained symptoms etc.
How to Perform the Test
Here’s how one typically collects a DUTCH test. The exact instructions vary slightly by panel. Use your kit’s instructions, but these are typical steps and considerations.
Receive the kit: Includes dried urine collection strips/papers, instructions, forms (health history, medications, cycle info for women).
Timing your collection:
If you have a menstrual cycle: usually collect in the luteal phase (second half of cycle), sometimes ~ Day 19-21 in a 28-day cycle (adjust if your cycle is longer/shorter).
If you opt for cycle mapping (highly recommended!!!), you’ll collect samples every day throughout your cycle.
If you don’t cycle, are male, or post-menopause: any representative day can be used, as long as the conditions around that day are typical of your regular state.
Sample collections over time (for many panels):
Several points in a day: e.g. dinner (~5pm), bedtime (~10pm), upon waking, a couple hours after waking.
Pre-test preparation:
Avoid unusual stress, intense exercise, excessive caffeine or alcohol near the time of collection.
For women, avoid using hormonal birth control if wanting baseline; certain medications/supplements might need to be paused because they can interfere. Ask me in the comments if you’re unsure whether you should pause any medications or supplements you’re currently taking.
Drying and shipping:
Let strips/paper dry thoroughly before sealing. The dried format helps with stability during shipping.
Send back to lab with all forms filled. Lab processes via advanced methods (mass spectrometry etc) for hormones + metabolites.
Sample Results & What They Mean
Below are sample result types.
Hormone Summary: A dashboard showing key hormones (e.g. estradiol, progesterone, testosterone) with where they fall relative to ranges (for people in similar life-stage). Might include “normal / high / low” labels.
Adrenal (Cortisol) Curve: Graph of free cortisol/cortisone levels across the day (waking, mid-morning, afternoon, night), showing whether the natural diurnal rhythm is preserved or flattened or too high/low at certain times.
Metabolite Pathways: For estrogens – how the body is converting / “detoxifying” estrogen (which hydroxylation pathways are active, methylation capacity etc.). For androgens, whether conversion favors more androgenic vs less androgenic metabolites (e.g. 5α-pathway vs 5β-pathway). This matters for symptoms like acne, hair loss etc.
Organic Acid / Oxidative Stress / Melatonin: These may show markers of oxidative DNA damage, melatonin metabolite (sleep quality insight), nutrient status (vitamins B6, B12 etc.), neurotransmitter breakdown products.
Who Should Consider It
Women
Irregular cycles, PMS, heavy flow, mid-cycle anxiety, perimenopause insomnia.
Acne or hair shifts that don’t match your bloodwork story.
Fertility questions where timing and luteal sufficiency actually matter.
Men
Low morning drive, flat workouts, slow recovery, irritability at night.
Skin or hair changes when “total T” looks fine.
Midlife shifts in body composition and sleep that don’t show up in a single AM lab.
Reading the Map Without Getting Lost
A few patterns that actually translate into symptoms:
Low morning cortisol with evening elevation: hard starts, wired nights, broken sleep.
High total cortisol, especially late day: agitation, mid-afternoon crashes, stubborn belly fat.
Low luteal progesterone relative to estrogen: PMS, heavy or painful periods, sleep fragility, anxiety spikes.
Estrogen metabolism leaning toward 16-OH with poor methylation: breast tenderness, fluid retention, cycle heaviness.
Androgen metabolism favoring 5-alpha: jawline acne, hair shedding, oily skin—even if total testosterone is “normal.”
Low DHEA/testosterone in men or women: flat libido, slow recovery, low drive.
The point is not to memorize pathways. The point is to match data with felt reality, so interventions stop being guesses.
Only a small group of providers really know how to read these reports, so finding someone experienced is key. When I first got my results, my OB-GYN literally turned the pages over in her hands and admitted she had no idea what she was looking at. I ended up teaching myself — digging through articles, cross-checking pathways — just to make sense of it. Honestly, it’s not that hard once you understand what you’re looking for. If you’re unsure, seek out an HRT or functional medicine specialist, or use one of the newer AI tools to help you parse the data. Back when I did it, there was no such shortcut; I had to decode everything by hand. With today’s tools, you finally have no barrier to understanding your data — run the panel and see what’s actually happening.
Sample Story / Case (Hypothetical)
Jane, 38, with irregular cycles, heavy periods, mood swings. She does a DUTCH Cycle Mapping. Her results show elevated estradiol, but estrogen metabolic pathways favour the 2-hydroxy (good) rather than 16-hydroxy (less favourable), but methylation is weak (bad). Also her progesterone is low in luteal phase. Adrenal curve shows elevated evening cortisol. Interventions: dietary support for methylation (folate, B12, methyl donors), reduce evening stress (sleep hygiene, adaptogens), support progesterone (nutritional + possibly bioidentical), cycle tracking, maybe herbs to balance estrogen metabolism. Over several months she reports lighter periods, more stable mood, better sleep.
Blind Spots and Caveats
It’s not a diagnostic for rare endocrine disease. If something looks extreme, you still pursue medical work-up.
Collection errors and bad timing can muddy results. Respect the instructions.
It costs money and often isn’t covered by insurance. Consider cost against months or years of trial-and-error.
If You’re Starting Here
Get clear on your question. What is bothering you most? Sleep? Skin? Cycle? Energy rhythm? Pick the thread you actually want to pull.
Run the right panel and collect on the right days.
Match findings to symptoms before touching a single supplement.
Intervene in sequence, not all at once: circadian and meals first; then specific pathway support; then re-check.
Retest when you’ve actually changed something. Otherwise you’re just doing expensive scrapbooking.
I did not get better by chasing everyone else’s fix. I got better by seeing my own map, choosing targeted steps, and sticking with them. I’ve laid the protocols out in other pieces - bile support, circadian repair and nutrition, progesterone and nutrient cofactors, thyroid support - so you can borrow what helps and skip what doesn’t.
Remember: you doctor standard “within range” is not the same as “well.” If your body feels wrong, listen. Then measure what matters, so the treatment fits the problem you actually have.
Sound like too much work - maybe even intimidating? Think of it as a quest, a quest for your own health. It’s a worthwhile investment that will pay off. Take matters into your own hands and start getting better.

What would be the mechanism behind somone having oestrogen dominant symptoms but the DUTCH test showing LOW oestrogen (like menopausal range) and normal progesterone in a perimenopausal woman who is also taking HRT (oestrogen and progesterone) ? Could it be due to fluctuating oestrogen levels during this time or maybe oestrogen being stored in the tissues like Ray Peat says?
