How we research, test and correct these guides
Short answer
Every guide on this site follows four rules: claims are traceable to a named source, measurements are published rather than asserted, we say what we do not know, and corrections are logged with a date. This page explains the standard and how to challenge it.
The four rules
- A source or a measurement, never a vibe. Health, safety and performance claims cite a named study, standard or regulator. Where we publish a number, we say how it was obtained and what it does not cover.
- Tools publish their method. Every calculator on this site lists the inputs, the formula and the assumptions underneath it, so you can disagree with the maths rather than the conclusion.
- We state the limits. If the evidence is thin, mixed or absent, the page says so. Band research measures strength, not muscle size — so a page about muscle size says that out loud.
- Corrections are dated and visible. When we fix something substantive, the change and its date go on the page.
What we will not do
| Not this | Why |
|---|---|
| Invent statistics or attribute them vaguely ("studies show") | It is the fastest way to lose the reader and the search engine at once |
| Publish fake reviews or review counts | The store sells the products; the guides are allowed to say when a product is the wrong choice |
| Hide the commercial relationship | This is a store. Guides exist to help you buy the right thing once, not to pretend the shop does not exist |
| Copy a competitor guide and reword it | Every guide here is built from the source material and our own tool output |
| Give medical advice | We explain mechanism, evidence and safe use. Diagnosis and treatment belong to a clinician |
How a guide gets written
- We start from the question people actually ask — from search result question boxes, support tickets and returns data.
- We pull the primary sources on that question: position stands, meta-analyses, regulator guidance, manufacturer specification sheets.
- Where a decision depends on a number, we build a tool instead of describing the number in prose.
- We write the shortest version that answers the question, then add the detail that stops the reader making a bad choice.
- Before publishing, a second pass looks for overclaiming: any sentence that asserts more than the cited source supports gets cut or softened.
Corrections and contact
If a page here is wrong, out of date, or cites something that has since changed, tell us and we will fix it and note the date. Reach us via the contact page.
On conflicts of interestWe sell the products these guides discuss. That is a real conflict, so the standard is disclosure, not denial: guides recommend the right tool for the job even when it is the cheaper one, and say plainly when a product is unnecessary.
