In the vendor's own words
Written by the vendor · Not verified by PeptideBase
Costides is a United States supplier of research peptides, fulfilling orders from a US warehouse and presenting its catalogue for laboratory research use only, not for human or veterinary use. Products are sold as multi-vial packs aimed at laboratory procurement rather than single units. The site states that certificates of analysis are available, with purity measured by HPLC and mass spectrometry and identified by lot number, and publishes a certificate index. Those are the vendor's own statements; PeptideBase has not independently verified them and holds no laboratory records for this supplier.
