How we make money, and what we will not do for it

Two minutes of reading that should make the rest of the site easier to trust.

Referral links

Some of the links that take you to a supplier carry a referral code. If you order after clicking one, the supplier may pay us a commission. You pay the same price either way. Not every supplier offers such a link, and having one or not has zero effect on a supplier's stars, its position in the table or the words on its page.

Our ties to the industry

The people behind Rated Peptides have worked in, and hold financial interests in, the research-peptide supply business, including with suppliers that appear here. We handle that conflict the only way we think is honest: the formula is published in full and runs the same for everyone; each fact on a review cites where it came from; and the whole dataset is downloadable so you can rebuild the table without us. Where a listed supplier is connected to the people behind this site, the review says so.

Things we turn down

  • Money for a listing, a position, a rating or a sentence.
  • Free product in return for coverage.
  • Requests to delete accurate negative facts such as warning letters, closures or gated certificates.

Fixing mistakes

Anyone, supplier or reader, can ask for a factual correction through the contact page. Show us the evidence and we will change the fact. We do not change ratings on request; they change when the facts do.
