Quality control
At NeoPeptidos every batch goes through an independent analytical verification process before it becomes available. Full transparency, from start to finish.
Every compound goes through a strict verification process before it becomes available in our catalog.
We work exclusively with manufacturers that have GMP-certified facilities and documented synthesis processes.
Each batch is verified by high-performance liquid chromatography (HPLC) to confirm a minimum purity of 99%.
A unique Certificate of Analysis is generated per batch with a serial number, date, analytical results and the laboratory's signature.
Lyophilized peptides are kept refrigerated at 2–8°C in our warehouse and travel in their stable powder form, which tolerates room temperature for weeks without losing integrity.
The COA (Certificate of Analysis) is the document that certifies the identity and purity of each compound. It is issued by the laboratory that performed the chromatographic analysis and contains:
The published certificates are checked directly in the issuing laboratory's system, with the code printed on the document. No account and no intermediaries.
Verify a certificate ↗The party that manufactures the peptide is not the one that certifies its purity. That separation is deliberate, and it is what makes the result mean something.
Solid-phase synthesis · batch traceability
We work with manufacturers that operate GMP-certified facilities and document their synthesis process batch by batch. Supplier selection does not depend on price: we require documented process control and traceability from the raw material before adding any reference to the catalog.
The manufacturer's identity is shared with wholesale customers and distributors under a confidentiality agreement.
Carlsbad, California · analytical laboratory
The certificates of analysis are issued by Elemental Purity Labs, an independent laboratory that neither manufactures nor sells peptides. Each certificate is published at a permanent address that anyone can check, without an account and without going through us.
Each certificate corresponds to a specific batch and was issued by Elemental Purity Labs, an independent analytical laboratory. You can open any of them and check the results directly in the laboratory's verification system, without an account.
Verify a certificate by code ↗Each of the certificates above can be opened and checked in the issuing laboratory's system with the code shown on the card.
View catalog →Our control program provides for twenty certificates of analysis per production batch. Since the catalog is extensive, that quota is assigned to a subset of references per batch, so not every presentation in the catalog is part of the analysis of a given batch. The certificates shown on this page are those issued under the current program.
Each certificate applies exclusively to the batch and sample identified in the document, and describes the sample as received by the laboratory. The results do not extend to other batches or other presentations of the same compound.
