PepFinder Score
ProvisionalReviews are moderated before publication. Suppliers can reply but cannot remove them. Review policy
Each rating shows where it comes from. Automated data is what we read from the supplier's website and listings; customer ratings take over as reviews come in. No customer has reviewed this supplier yet. Be the first. Payment for a listing never changes a rating.
No website can promise that a supplier is trustworthy. These are the checks we can make from public records, the supplier’s own website and our reviews. They are the same checks as in our guide to spotting an unreliable supplier.

Product names, photos, quantities and prices are as publicly listed by the supplier; photos load from the supplier’s own website. “vs market” compares price per mg with the median across tracked suppliers listing the same peptide in the same currency; prices are never converted between currencies. We do not sell these products and give no guidance on their use.
Pros and cons appear here once at least 5 customers have rated the same part of the experience. We don't write them ourselves. Write a review

For readers who want the detail: what Crown Peptides says about testing, the certificates of analysis we hold, and our Transparency Score. This is separate from the PepFinder Score above.
Transparency review · updated 24 Sept 2026
Crown Peptides is a United Kingdom-based research-peptide supplier listing 22 of the peptides we track, priced in GBP. Where it does well: links a certificates-of-analysis page (not yet reviewed by us); states a company registration number (17068950). Where it falls short: we found no statement of independent testing on its website; we found no refund or returns policy. Our Transparency Score is 4.5/10, provisional until more of our criteria have been assessed.

Crown Peptides links a certificates-of-analysis or lab-results page. PepFinder has not yet collected or reviewed any of its certificates, so this is the supplier's own claim.
We record what testing documents state and where they came from. We do not test products, and a certificate is not evidence that a product is safe for any use.
We cannot vouch for any supplier, but we can report what the record shows. Crown Peptides meets 3 of the 9 checks we make, with nothing flagged. Each check, and its source, is listed on this page.
Our records place Crown Peptides in United Kingdom, trading as Crown Peptides Ltd.
Crown Peptides states that it ships to Australia, Canada, United Kingdom, New Zealand, United States. Check the supplier's own shipping policy before ordering.
