Peptide testing laboratory

Certificates of Analysis you can verify.

Cert-Lab tests peptides and keeps a controlled record for each released report. Use the COA number to check whether that record is current, withdrawn, or replaced.

Quality

A report is released only after review.

  • Samples are registered and tracked through the work.
  • Methods are used within the scope agreed for the study.
  • Results are reviewed before a report is issued.
  • Each released report can be checked by its COA number.
  • A withdrawn or replaced report stays on record with that status. It is not shown as a current result.

Check a report number.

Verification shows the status held in this system and the fields the laboratory has released.
