Does every order include a COA?
Yes. A batch-matched certificate of analysis is published for every batch, showing purity by HPLC, identity by mass spectrometry, appearance and the release date for that specific lot. Certificates can be viewed and downloaded from the Certificate of Analysis section for each peptide.
How do I verify a certificate against my vial?
Match the batch code printed on the vial label to the batch number on the certificate. If the two do not match, stop and contact us before beginning any work.
Is testing carried out independently?
Yes. Batches are tested by an independent third-party laboratory in addition to in-house analysis, so the purity and identity figures on the certificate are not self-reported alone.
