## Method

- Source: the third-party COAs that Curo publishes on the [COA library](https://curo.you/coa). 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. Archived copy of the lot table: https://zenodo.org/records/22706906
