About Rated Peptides

Rated Peptides is written for the person in a lab who has to place the order: the one who needs a supplier that will ship on time, show its certificates and still be in business next quarter.

What you get here

For each supplier we gather the facts a careful buyer would want (testing, certificates, company details, range, prices, shipping and payment terms) from the supplier's own pages and from public records. We feed those facts into one published formula and show the resulting star rating along with every number behind it. You can read the formula and download the data.

Who writes it

A small editorial team that has worked inside the research-peptide supply business. That experience is why the ratings are formula-driven rather than opinion-driven, and why we publish a disclosure of how the site makes money and where our interests lie. Suppliers and readers use the same corrections route.

Lines we do not cross

• No customer reviews, testimonials or star ratings are collected, shown or marked up. Our stars are editorial.
• No paid placement. A referral link may earn us a fee, but it never enters the formula.
• No discussion of using what these suppliers sell. Everything listed is labeled for laboratory research use only, and nothing on this site is medical advice.
