Our editorial purpose
We publish educational, research-oriented material about peptide information and the documentation suppliers make public. Our aim is not to create certainty where the evidence is incomplete. We describe what a source supports, what remains unverified and where a reader can inspect the underlying material.
Research-only scope
Content on this site is not medical advice, diagnosis or treatment guidance. We do not publish personal protocols, dosing instructions, reconstitution directions or recommendations to purchase or use unapproved research materials. A research finding, supplier claim or certificate of analysis is not treated as proof of safety, efficacy, regulatory status or suitability for human use.
Evidence standards
We prefer original studies, lot-specific records and documents that can be traced to an identifiable issuer. We label supplier-provided material as supplier-provided, distinguish it from provider-verifiable records and keep secondary sources in their proper context. More public documentation can make a supplier easier to evaluate; it does not automatically prove better underlying product quality.
Scientific research is described in the context of its model and limitations. Cell, animal and human studies answer different questions. We do not turn preliminary findings into clinical conclusions.
Supplier comparisons and scores
Supplier reviews evaluate transparency, evidence coverage and documentation against the criteria published in our methodology. They are not certifications, endorsements or guarantees. We may withhold a numerical score when the available evidence does not justify that degree of precision.
Commercial features such as price, catalogue size, shipping or site design are recorded separately from analytical documentation. Missing information is not counted as positive evidence.
Affiliate disclosure and independence
Some links may be affiliate links. Where a commercial relationship applies, we disclose it on the relevant page and keep it separate from editorial scoring. Affiliate availability, commission value or discount codes do not increase a supplier’s score or change the evidence standard we apply.
We do not accept supplier copy as editorial content. A supplier’s own claims may be quoted or summarized only with their source and verification status made clear.
Authorship and AI assistance
Peptide Choice Guide identifies its founder and research editor on the About page. AI tools may assist with research organization, drafting, analysis and structure. They are not treated as scientific sources. Material scientific and factual claims should be checked against the underlying sources before publication.
Updates and corrections
Supplier catalogues, testing documents, policies and commercial relationships can change. Pages that depend on this information should carry a review date when appropriate. When a material error is identified, we will correct the page and update the relevant date or note rather than silently preserving an inaccurate statement.
If you identify an error or have source material that could improve a page, please use the contact route listed on the site. Submitting information does not guarantee publication, and it does not change the evidence standard applied to it.
