Peptigen is a UK-based vendor that serves both retail buyers and bulk orders across a modest catalogue. The site lists prices on most of its products, but testing documentation is limited—one vendor-hosted COA appears on file, with no peptides currently covered by third-party lab verification. There's not yet much community signal to draw from, so shipping reliability, product quality, and customer service remain open questions.

Anecdotal signals
Testing coverage
We hold lab certificates for this vendor, but none of them correspond to a product currently in their catalogue — so we cannot confirm what is in any vial you could actually buy. Testing scores zero until that mapping exists. This one is on us as much as them.

We don't issue verdicts — we publish the evidence and let it speak. So far we have captured no substantiated community reports and no lab documents for Peptigen. That absence is itself information: it does not prove anything is wrong, but it means independent evidence is thin — proceed accordingly.
