About Peptide Ranking

Peptide Ranking is a reference site for people who buy research peptides for laboratory work and want to know which suppliers can back up what they claim.

What the site does

We collect the checkable facts about each supplier (testing, certificates, company details, catalog, pricing, ordering) from its own public pages and from public records, run them through one published formula, and show the result with its working. The methodology is public and the data is downloadable.

Who is behind it

The site is produced by a small editorial team with a background in the research-peptide supply industry. Because of that background we publish an advertising and relationships disclosure, and we keep scoring formula-based so that no page depends on anyone's opinion of a supplier. If you believe a fact is wrong, the corrections route is open to suppliers and readers alike.

What the site will not do

• It will not collect, display or mark up customer reviews or star ratings.
• It will not accept payment for placement, and referral status never enters the formula.
• It will not describe or endorse any use of listed materials other than laboratory research. Nothing here is medical advice.
