Editorial policy.

Sourcing

Every factual claim about a compound's mechanism, evidence or regulatory status traces to a primary source — a peer-reviewed paper, a regulatory document, or a trial registry entry. Citations link out by DOI or PubMed ID so the source is one click away. We do not cite other content sites as evidence.

Where a claim rests on a single study, a small study, or a study from a single research group, we say so in the sentence that makes the claim rather than in a caveat at the bottom.

Dosing

We report published clinical-trial protocols, with the trial named and cited. We do not author dosing protocols, convert animal doses into human ones, or publish schedules for compounds that have never been dosed in a human trial. For most compounds covered here, no established human dose exists, and the correct thing to publish is that sentence rather than a chart.

How commercial links work

Articles link to a retailer where it carries a compound the article discusses, and this site earns revenue from purchases made through those links. Four rules constrain that:

• Coverage is not gated on stock. We publish guides on compounds the store does not sell and will not sell — bioregulators, discontinued drugs, compounds abandoned for toxicity. Roughly two in five compounds in the A–Z index are not stocked.
• Evidence sections are written before commercial ones. A product link never changes what the evidence section says. Where the evidence is weak, the article says the evidence is weak, next to the link.
• Rankings state their criteria and include us. This used to say we published no supplier rankings at all. That was the safe position rather than the useful one, and a reader asking where to buy was left to do the comparison themselves. We now publish them — ranked on stated criteria, every cell a document you can open, and the retailer we earn from in the same table on the same columns with its own limitations named. What we still do not publish is a score: nothing here has been rated.
• Disclosure on every page. Not a single buried page — the footer of every article states the relationship.

What we will not publish

• Therapeutic claims for compounds that are not approved for the indication
• Before-and-after photographs as evidence of anything
• Dosing protocols with no trial behind them
• Purity or accreditation claims we cannot substantiate
• Content that reads as encouragement to use a research compound in a human

Updates and corrections

Pages carry an updated date. When new trial data changes a conclusion we revise the page rather than publishing a second article that contradicts the first. Substantive corrections are noted on the page. Report an error to hello@wheretobuypeptides.org.

AI use

Drafting and research assistance involve AI tools. Every factual claim, citation and figure is checked against the primary source before publication, and the editorial responsibility for what appears here is entirely human. Articles carry the WTBP Research Team byline, which is the house name for that team.
