How to Verify a Freedom Diagnostics Peptide COA

A Certificate of Analysis is only as useful as your ability to confirm it is genuine and that it describes the material in your hands. This article walks through verifying a Freedom Diagnostics peptide report end to end: how the laboratory's lookup works, which analytical methods the report reflects, how the accession verification steps run, and how a specific Hermetica lot maps to its certificate. It is a documentation guide for qualified researchers, not a product use guide.

Who Freedom Diagnostics is

Freedom Diagnostics is an independent analytical laboratory offering peptide identity and purity testing. Like Janoshik Analytical — covered in our companion article — it is a contract service: a client submits a physical sample, the lab runs a defined set of analyses, and it issues a report tied to that sample. The laboratory is paid for the analysis, not for a favourable outcome, which is what distinguishes a third-party report from an in-house claim.

What the report measures: HPLC vs LC-MS

Freedom Diagnostics peptide reports typically rest on two complementary methods, and they answer different questions:

A high HPLC purity figure does not by itself establish net content, and an LC-MS identity match does not establish purity. Read both sections of the report; our guide to reading a peptide COA covers the field-by-field detail.

Accession verification: the steps

Each Freedom Diagnostics report carries a unique accession / report number. Verification happens at the laboratory, not on the vendor's website:

1. Read the accession number and analysis date from the certificate itself — not from a vendor's description of it.
2. Contact Freedom Diagnostics through its official channels and quote the accession number, or use any lookup facility the laboratory publishes, to confirm the record exists.
3. Compare every field: compound name, reported purity, sample identifier, and date. Any mismatch between the laboratory's record and the PDF is disqualifying.
4. Confirm the sample identifier on the report corresponds to the lot number printed on the vial you received. A verified report for a different batch tells you nothing about your material.

The last step is where most verification chains break. Batch-level correspondence is the entire point of the exercise.

A worked example: GHK-Cu lot M26S012

Our GHK-Cu 50mg lot M26S012 was submitted to Freedom Diagnostics, and the resulting certificate is issued under COA #2604070134. The mapping is deliberately simple:

• Vial label carries lot M26S012.
• Certificate COA #2604070134 names that lot as the sample identifier, and reports the compound identity and HPLC purity for that specific sample.
• Verification of accession 2604070134 with Freedom Diagnostics confirms the record independently of anything published on this site.

The certificate is published in full in our COA library alongside the Janoshik Analytical reports covering other catalogue lots, including those reviewed under analyst attributions such as D'Hondt and Hoofnagle where those citations appear on the underlying documentation.

What a Freedom Diagnostics report does not tell you

• It describes one sample at one point in time. It carries no information about storage, transit temperature, or handling after the sample was drawn.
• It says nothing about batches never submitted. Absence of a bad report is not evidence of consistency.
• It is not a quality system. A report is a measurement; traceability, lot control, and cold chain are separate disciplines.
