Weighting
Testing visibility
30%Readable COAs, lab-report visibility, batch specificity, and document access carry the heaviest weight in the review process.
Methodology
How we review peptide suppliers
PeptideSuppliers.org uses an editorial review framework built around public-facing information. The process weighs what a supplier makes visible on the page rather than treating polished presentation as proof.
The goal is to show how supplier pages are assessed for documentation quality, clarity, research framing, and overall buyer fit.
Weighting
Site clarity
25%Product pages, categories, policy pages, and support routes are scored for readability and ease of use.
Weighting
Research framing
20%Research-use-only language, disclosures, and educational boundaries are reviewed for consistency across the site.
Weighting
Buyer fit
25%Supplier positioning is interpreted through catalog depth, usability, and the type of visitor the page may suit best.
What is included
The review focuses on visible public information
Reviews are based on what the site publicly shows: COAs, product pages, category structure, policy clarity, contact information, and research framing.
That keeps the methodology tied to what visitors can inspect themselves.
- Documentation links
- Product-page clarity
- Policy detail
- Disclosure and RUO consistency
What is not claimed
A review is not a lab certification
A strong page can still leave important questions unanswered, and a weak page can still change over time. The methodology is meant to explain editorial rankings, not replace independent due diligence.
That distinction is central to the way the site frames supplier reviews.
- Not a purity guarantee
- Not legal guidance
- Not a medical recommendation
- Not a substitute for independent verification
