pep3 supplies analytically verified research peptides to laboratories, universities and independent investigators. We started with a simple idea: every vial should be traceable to a published, independent test result — no exceptions.
What we do
We source peptides produced by solid-phase peptide synthesis, purify them by preparative HPLC and release a batch only after an independent laboratory has confirmed identity and purity. Each vial carries a lot number that links to its Certificate of Analysis in our public COA library.
Independent testing
Purity by HPLC and identity by mass spectrometry, performed by accredited third-party laboratories.
Full traceability
Batch-level certificates you can look up by lot number before and after you order.
Careful handling
Lyophilized for stability, stored cold and shipped in insulated, discreet packaging.
Our quality standards
- Target purity of ≥99% by HPLC for catalogue peptides
- Identity confirmed by mass spectrometry for every batch
- Certificates of Analysis published for every lot we sell
- Temperature-controlled storage from receipt to dispatch
- Clear research-use-only labelling on every product
Research use only
Our products are intended strictly for in-vitro laboratory research. They are not drugs, food, supplements or cosmetics and must not be used in humans or animals. We reserve the right to refuse orders that suggest otherwise.
