How this guide was made

01Who wrote it

Sean, who makes n1lab, wrote this guide with an AI research assistant. Neither is a clinician or a researcher, and no clinician has reviewed the guide. It describes what published research says about running a careful one-person test. It is general information, not advice about anyone’s health.

02How the sources were found and checked

The guide started from two research briefs written in October 2026. One covered methods for one-person trials, single-case designs and self-experiment tools. The other covered how symptoms are measured and how food challenges are run. Together they drew on about a hundred sources: journal papers, reporting standards, and guidance from professional and public bodies.

Each source was checked against its own record: its PubMed entry, its DOI record, or the publisher’s page. The authors, year, title, journal and identifiers in the References come from those records.

The References page also says what was read for each source. For many papers that was the abstract only. Each page is written to claim no more than what was read supports, and a claims review checks it before the page goes live. Where a source couldn’t be read, it isn’t cited.

03How the pages were written

Every summary was written fresh from the source, in plain words, rather than copied from it. Quotes are rare and short, and always say whose words they are. The guide links to each source’s record and hosts no copies of papers.

The names of conditions, and the words studies use for medical care, are kept to sentences that report what a named study did or found. They never appear in titles or headings. The one exception is n1lab’s Help cautions on when to ask a doctor first, repeated word for word on the safety page and on Bringing a food back. No medicine is named outside a source’s own title.

Before a page goes live, it is checked against Australian rules on health claims and advertising, and against n1lab’s own wording rules. Those checks are done in-house, with AI reviewers. They are not legal or clinical advice.

04What’s left out, and why

• Evidence on specific diets. This first release covers methods only, so research on particular diets is held back.
• A page on n1lab itself. A page comparing what n1lab does with this research is written, and held back too. Both wait until n1lab has had professional advice on how health rules apply to it.
• Some practical topics. Hiding what’s being tested with a helper’s help, worked examples, and tests of sleep, caffeine or exercise are planned but not written yet.

05Keeping it current

Each page shows the date it was last checked. Research moves: papers are corrected or withdrawn, and newer reviews appear. Each source shows the date its record was last checked, and a page changes when what it says no longer holds.

These pages carry no analytics and no third-party ads, because what someone reads about health can hint at their health. The box at the end of each page is about n1lab.

06Reporting a mistake
