Questions
- What does full panel tested mean?
- Four tests on the same product at an independent laboratory: purity, mass, bacterial endotoxins and sterility. Purity and mass are the usual pair on a peptide certificate. Endotoxins and sterility are the two that most certificates leave out.
- Are the peptides third party tested?
- Yes. The tests are run by an independent laboratory, not by Peptx and not by the manufacturer, and the certificate is published exactly as the laboratory issued it.
- Is the testing finished?
- Each product on this page is booked at an independent laboratory for all four tests. The first results are due at the end of October 2026 and each one is published in the COA Library as it is issued.
- Where are the results published?
- In the Peptx COA Library, exactly as the laboratory issued them. Each test is listed there from the day it is booked, with its laboratory and its due window, so a result can never appear only when it is good.
- How do I find out when they land?
- Create a free Peptx account and press Notify me. We email you as each product arrives in UK stock. You can leave the list at any time from your Portal.
- What are these products for?
- They are research reagents, sold for laboratory research use only. They are not medicines and are not for human or veterinary use.
