Certificates Of Analysis And HPLC Testing

We work only with research grade peptides and NAD+ formulations and verify every supplier through independent laboratory testing before a batch is ever used in our pens.

On this page you can review selected Certificates Of Analysis (CoA), HPLC chromatograms and other analytical reports from our partners, including certified laboratories in the EU and USA. The goal is simple: transparent data behind every molecule.

Important: Not every single production batch has a separate public CoA. For some products we publish representative reference certificates that illustrate purity, identity and analytical method used for that peptide. Internal HPLC testing and in house quality checks are performed on an ongoing basis.

How To Read Our Certificates

  • Purity: Most CoA documents will show peptide purity as a percentage based on HPLC or similar analytical methods
  • Method: HPLC chromatograms and method sections describe how the sample was tested and which column, solvent and gradient were used
  • Identity: Some reports include mass spectrometry or additional data that confirm the exact peptide sequence or molecular weight
  • Lot information: Batch or lot numbers on the certificate may not always match your retail unit but refer to the larger production batch from which it originates
