Method

  • Source: the third-party COAs that Curo publishes on the COA library. Each lot counts one time.
  • A lot counts as tested when its COA states an HPLC purity. Lots that wait for lab results are not in the numbers.
  • Fill is the measured amount as a share of the label amount. Vials are filled above the label amount, so a fill above 100% is expected.
  • Bacteriostatic water is not a peptide, so its lots are not in the numbers.
  • Purity shows one decimal place, as on the COA. Fill and shares are rounded to whole percent.
  • The page updates when a new lab report is published. Read how Curo tests every lot. An archived copy of the lot table is on Zenodo.
