What is a Janoshik CoA and How Do You Verify One?

September 18, 2026 · By My Store 3 Admin

When evaluating research peptide suppliers, the quality and authenticity of testing documentation is a critical factor. A Certificate of Analysis (CoA) from a reputable independent laboratory provides assurance of compound purity and identity — but not all CoAs carry the same weight. This article explains what a Janoshik CoA is, why independent third-party testing matters, and how researchers can verify results directly.

What is Janoshik Analytical?

Janoshik Analytical is an independent third-party analytical laboratory that specialises in testing research compounds, including peptides, nootropics, and related substances. It is widely used within the research compound supply chain as an independent testing provider, and its reports are recognisable by researchers due to their online verification capability.

Janoshik operates independently of suppliers — results are recorded and held on Janoshik’s own systems, separate from any supplier’s control. This independence is what gives third-party CoAs their value: a supplier cannot alter or fabricate results held on an independent laboratory’s database.

What Does a Janoshik CoA Include?

A standard Janoshik Certificate of Analysis for a research peptide will typically include:

  • Compound identification — Name, CAS number, molecular formula, and molecular weight
  • Batch/order reference — A unique identifier linking the CoA to a specific test order
  • Purity result — Expressed as a percentage, determined by HPLC (High-Performance Liquid Chromatography)
  • Identity confirmation — Mass spectrometry (MS) result confirming the compound’s molecular weight matches the expected value
  • Test date — Date the analysis was performed
  • Verification QR code or reference — Enables independent online verification

How to Verify a Janoshik CoA

Janoshik provides an online verification portal that allows anyone to confirm that a CoA document is genuine and matches the result held in Janoshik’s own records. To verify:

  1. Locate the order reference number on the CoA document (typically in the format of a numeric code)
  2. Visit verify.janoshik.com
  3. Enter the order reference number
  4. The portal will display the results held on Janoshik’s system — compare these to the CoA document provided by the supplier

If the results match, you can be confident the CoA has not been altered. If no result is found, or the figures differ from the supplied document, this is a significant red flag.

Why Third-Party Testing Matters

In-house testing — where a supplier tests their own products using internal equipment — provides no independent verification. There is no external check that the results are accurate, or that the document has not been manipulated. Third-party testing by an independent laboratory removes the supplier from the analytical chain entirely: the sample is sent to an external lab, analysed by staff with no commercial relationship to the supplier, and the results are recorded independently.

For researchers making procurement decisions based on compound quality, independent third-party CoAs are the minimum standard for credible quality documentation.
