Reading these results

  • Identity (LC-MS) confirms the material’s molecular mass matches MOTS-c.
  • Net content is the measured amount of peptide in the vial compared with the label amount.
  • Purity (RP-HPLC) is the main peak as a percentage of all detected material. All three batches exceed the 98% specification.
  • The chromatogram on each Kovera Labs certificate shows a single dominant peak for MOTS-c.

Verifying a certificate

Kovera Labs certificates list a report number and access code with a QR code for the lab’s verification page, and SteriGenix certificates carry a report number. Compare the report number, batch and results on the lab’s site with the certificate.
