# Editorial policy
This page sets out the rules every page on BPC-TB Guide follows. It exists so that you can check our work against our own standard. If you find a page that breaks a rule here, that is an error and we want it corrected.
1. Source hierarchy
We rank sources in three tiers and say which tier a statement comes from.
- Regulators and public-health bodies. FDA pages and briefing documents, the World Anti-Doping Agency (WADA) Prohibited List, the United States Anti-Doping Agency, NIH pages, and federal registers and statutes. These are our primary sources for legal and regulatory status.
- Peer-reviewed records and registries. PubMed records, Cochrane reviews, systematic reviews and trial registrations on ClinicalTrials.gov. These are our primary sources for evidence. We read the record itself, with its design, species, size and stated result, and we do not rely on a summary of it.
- Commercial, clinic, news and forum pages. These are claims. We may say what a page claims, attribute it in the sentence, and grade it against tier 1 and tier 2. We never cite such a page as evidence, never link to it, and never name a clinic, shop or seller.
We link only to tier 1 and tier 2 sources. A statement we could not confirm in a primary source is left out, or marked "we could not confirm".
2. The grade key
Every claim ledger on the site uses the same five grades, with this exact wording.
- Human trials support. Controlled trials in people support the claim.
- Small human reports only. The only human data are small, uncontrolled or case-level reports.
- Animal or lab studies only. The support is from animals, cells or other laboratory work.
- No published support found. We searched and found nothing that supports the claim.
- Contradicted by sources. A regulator or a primary record states the opposite.
A grade describes the published record on the date shown. It is not a judgment about whether anyone's experience was real, and it is not a statement about safety. We do not raise a grade because a clinic, a forum or a famous name says so.
3. The dating rule
Rules, pages and trials change, so we date them. Every statement of regulatory status carries the date of the source, such as "FDA page current as of 2026-04-22", and each table ends with an "as of" line. Sources are listed with the date we read them. We write dates in absolute form, never "last week" or "recently". When a regulator posts something new, we update the page and change the date.
4. The attribution rule
Words that praise or compare a compound or product, such as better, stronger, faster or more effective, appear only when we say who used them, for example "a clinic page says". We never use words that certify a compound, such as a safety or effectiveness verdict, in our own voice. We do not use "best", "top" or "leading" without saying who made the ranking. Quotations stay under fifteen words and carry the name of the source.
5. What we leave out
- Doses, schedules and how-to instructions. We name no dose, even when a study used one, and we explain why in the pages on dosing.
- Names of sellers, clinics and individuals. We name no seller, clinic or business. We name no athlete. Researchers appear only as authors of a cited record, by surname and year.
- Personal-story marketing. We run no reader stories or customer accounts, and where we mention before and after claims, it is to explain why they are weak evidence.
- Urgency. We use no countdowns and no pressure.
- Credentials. We list no credentials and make no review claim we cannot back up.
6. Describing studies
For a study we say the design, the species, the number when the record gives one, what was measured and the stated result. We also say what it does not show. We separate cell work, animal work, small human reports, controlled human trials and registered but unfinished trials.
7. Funding and independence
As of 2026-10-09 the site carries no advertising and no affiliate links, and has no sponsor. No company that makes or sells the compounds we discuss pays us, reviews our pages or sees them before publication. If this changes, we will state it on the About page and on each affected page, and record the change in the log below.
8. Corrections
When we find an error, we fix it on the page and add an entry to the correction log below with the date and what changed. When a source changes, we update the dated statement and its "as of" date. Typos fixed without changing meaning are not logged.
