About Us
About Peptide Origin
Peptide Origin Limited is a UK company supplying research compounds to laboratories, academic institutions and professional researchers. We are registered in England and Wales, company number 16688695, and ship from London.
We source our compounds rather than manufacturing them. Every batch we take in is sent for independent analysis before it is offered for sale, and the resulting certificate is published in full on our COA page — not summarised, not selectively quoted. If you can see a product on this site, you can read its analysis before you buy.
How Our Testing Works
Batches are analysed by one of two independent laboratories for conformity and purity before release. Testing confirms two things: identity, that the material is the compound stated, and purity, the proportion of that compound relative to related substances.

A certificate reports on the sample tested at the time of testing. It confirms what was in that batch; it is not a warranty of fitness for any purpose, and it does not certify any product as safe for use in or on humans or animals.
What You Can Expect
Three things we commit to, and which you can check for yourself.
Independent Testing
Every batch is analysed by one of the two laboratories named above before release. We do not test our own material.
Published Certificates
The complete certificate for each batch is published on our COA page. Match the batch code on your vial against it.
