Certificates of Analysis (CoA)
Every lot is tested by independent laboratories using HPLC/LC-MS to confirm identity and purity before it goes on sale.
Independent laboratory
Testing is carried out by specialised external laboratories, unconnected to the peptide manufacturer.
Identity and purity
FTIR/LC-MS confirms that the vial contains the stated peptide; HPLC measures purity and potency against the label.
Per lot, not generic
Each certificate corresponds to a specific lot number, with the test date and the laboratory's signature.

Certificates of analysis correspond to specific lots received from our suppliers and are replaced as new lots are restocked. If you need the current CoA for a specific lot, contact us stating the product. All products are for scientific research use only, not suitable for human consumption or veterinary use.
