GHK-Cu lab reports: certificates of analysis by batch

GHK-Cu50mg100mg

This page lists every lab report we have published for GHK-Cu, one per tested batch. The reports come from three sources: tests we commission ourselves at an independent laboratory, independent third-party tests commissioned by someone else, and the batch certificate the manufacturer passes on. We do not run the testing ourselves.

Each card shows the laboratory, the batch identifier, the test date and what that report covers. Where the laboratory publishes the result, the verify link opens it on the laboratory's own server, and the report file is the one we received, unchanged.

Independent testing is being rolled out batch by batch; not every product is independently tested yet. The verify link is shown only for batches we actually sent to the lab.

Independent third-party lab tests

These batches were tested by an independent third-party lab (e.g. BT Labs), commissioned by our supplier or the wider research community, not by us, and passed on to you. Not a manufacturer self-report.

How to verify a report

  1. Open the report and read the laboratory name and the batch identifier on it.
  2. Follow the verify link. It opens the laboratory's own page for that report, outside our site.
  3. Compare the laboratory page with the report here: laboratory, batch identifier, test date and results have to match.

Frequently Asked Questions

  • A high HPLC purity figure reflects organic impurities only; it is not the same as peptide content.
  • Neither laboratory is ISO 17025 accredited. Reports reflect the specific batch tested.
