What this site is
Biology Verdict is a buying guide for equipment, tests, wearables and supplements. It compares documented practical benefits, costs and trade-offs. It does not give medical advice, promise a health outcome or claim to be an independent medical-review service.
Biology Verdict is written by Porsche Ma, cofounder of Superhuman Chambers. His profile explains his background and work at the site.
How reviews are written
Each review names one model or variant and cites maker pages and manuals, certifier listings, regulator records and published studies where relevant. Specifications, prices, policies and certifications stay within what the source says. When sources disagree, the review says so.
Research is source-based. Biology Verdict does not present its reviews as hands-on product testing. Anything we could not confirm is recorded as unknown, rather than filled with guesses or figures from another model.
How health claims are handled
Evidence ratings assess a stated claim in a stated population and modality, from Strong to Not supported. A study of an ingredient, a technique or a category does not prove that a specific product works.
Not supported means the cited evidence does not support the stated claim. It does not mean the claim has been proven ineffective. Pages on tests, wearables and supplements are general information, not medical advice. Talk to a clinician before acting if you have a health condition or take medication.
How picks are made, and who pays
Picks follow the criteria listed in each buying guide, such as certification, running costs, warranty and return terms. They are picks for different needs, not a universal ranking. A health-claim rating is separate from a buying pick.
We plan to fund the site through affiliate links, not ads. Each review says under its price button whether that link pays us. A commission never decides a pick or rating, and there are no paid placements or sponsored reviews. The funding page gives the disclosure.
Updates and corrections
Prices, policies and sources are reviewed when a page is revised or material information is reported. Displayed check dates describe the recorded review, not continuous monitoring. If you spot a mistake, our corrections page explains how to report it.
When a correction changes a factual claim, rating or conclusion, we update the page and its date. This process is editorial review of the cited material. It is not a claim that every page has had independent medical review.
