About PepFinder
An independent place to compare research peptide suppliers on the things that matter: testing, prices, delivery, service and what customers say.
Why we exist
Hundreds of websites sell research peptides, and from the outside they look much the same. The product is a white powder in a vial, and the evidence about what is actually inside it is scattered across certificates, forums and review sites that are often run by the sellers themselves. PepFinder brings that evidence together in one place and shows where every piece of it came from.
What we do
- List suppliers serving the UK, the US, Canada, Australia and New Zealand, in the supplier directory.
- Read each supplier’s public catalogue and prices, so you can compare price per mg in your own currency.
- Record the certificates of analysis suppliers publish and score how open they are about testing: see third-party testing explained.
- Collect moderated customer reviews that suppliers cannot remove, under our review policy.
- Rate every supplier on the buying experience, with the source of each rating shown, as described in the methodology, and publish rankings only where there is enough data.
- Write neutral, referenced peptide guides and practical buying guides.
What we do not do
- We do not sell peptides or take orders.
- We do not give medical advice, and we never describe a product as safe.
- We do not let payment change a rating, a ranking, a review or anything we write. Our editorial policy and advertising policy explain how that is enforced.
