Research-Grade Peptides
You Can Actually Verify.
xPeptides exists to bring transparency to a market full of unverifiable claims. Every batch we ship is third-party tested, every COA is public, and every number on it can be independently checked.
How we prove purity
Every batch is analysed by HPLC (High-Performance Liquid Chromatography) and mass spectrometry to confirm identity and ≥99% purity. We don’t ask you to take our word for it — testing is performed by an independent third-party laboratory, and every Certificate of Analysis carries a unique verification key you can check yourself.
- ≥99% purity by HPLC
- Mass-spec identity confirmation
- Independent third-party lab
- Per-batch COA, publicly linked on every product
- Full batch traceability

Our story
We started xPeptides after buying one too many vials with no COA, no traceability and no way to know what was actually inside. The research-peptide market runs on claims — we wanted receipts. So we built the supplier we wished existed: one where the certificate of analysis is public, the lab is independent, and the logistics are boring and reliable.
