If only one of these flags is present, is the COA fake?

Not necessarily. Any single flag is a reason to ask the supplier for a corrected or fuller document. Multiple flags together strongly indicate fabrication. The batch-number mismatch (flag 1) is the most decisive on its own.

What if a supplier refuses to share a batch-specific COA?

Refusal to share a batch-specific COA is itself a final-stage red flag. A legitimate research-grade supplier publishes the COA per batch and can link you to the document.

Where can I see an example of a clean COA?

Every Peptify product page links to its batch-specific Janoshik Analytical COA. The BPC-157 batch 2026/04 report is a current reference example, downloadable from peptifyuk.com/product/bpc-157-10mg.

How to Spot a Fake Peptide COA: 5 Red Flags

Why a fake COA is the central scam vector

Most peptide-supply scams don't bother fabricating the powder — they fabricate the paperwork. A vial that looks fine, a label that looks professional, and a generic PDF labelled "Certificate of Analysis" together cost a scam supplier nothing. The buyer who doesn't audit the document treats it as proof. The buyer who does audit it sees the same five tells, every time.

What follows are the five tells. None require specialist equipment. All are checkable from the PDF and the vial in hand.

Red flag 1 — the batch number doesn't match the vial

The single most important check. Every legitimate COA is anchored to a specific production batch, and the batch number on the COA must match the lot number printed on the vial.

If the document is for batch 2025/09 and the vial says 2026/04, the document doesn't apply to the vial — full stop. It tells you nothing about the purity of what you have. Generic COAs that are reused across batches are common in low-end supply chains and are unfalsifiable except by this single check.

The Peptify Janoshik COA for BPC-157 batch 2026/04 carries that batch identifier on the report itself and on the vial label. If the two match, the document is anchored to the material.

Red flag 2 — no chromatogram image

A real HPLC purity report includes the chromatogram. The chromatogram is the visual trace showing peaks plotted against retention time, with the target peptide peak integrated and a peak-area table or equivalent.

A document that states "Purity: 99%" with no chromatogram is a claim, not a result. The chromatogram is the evidence that produces the number. A real lab includes it because it is what justifies the purity figure.

If you receive a one-page document with a purity percentage and no trace, you are looking at marketing copy formatted as a certificate. It is not a report.

Red flag 3 — no mass spectrometry section

HPLC measures purity. Mass spectrometry confirms identity. A full peptide COA should include both. A mass-spec section shows the observed molecular weight of the sample compared against the theoretical mass of the peptide, with the observed mass falling within instrument tolerance (typically ±0.1%) of the theoretical.

Without the mass-spec section, the document tells you that something is pure, but doesn't confirm that the something is the peptide it's supposed to be. This is a hole that fake-COA suppliers consistently leave open. Demanding a mass-spec section as part of every COA is a single change that filters out a lot of low-quality material.

Red flag 4 — no testing lab named

An anonymous COA is unverifiable. If the document doesn't name the testing laboratory — with an address, a country, and ideally a verifiable web presence — you cannot independently check the result. You can't ask the lab whether they performed the test. You can't establish that the lab exists.

Real labs name themselves on every report because their commercial reputation depends on it. Janoshik Analytical, for example, prints its name and address on every COA it issues. PeptideVerify does the same. A document that lists no lab is structurally less trustworthy than one that does — even before you assess the analytical content.

Red flag 5 — internal inconsistencies

Once you have run the first four checks, scan the document for internal inconsistencies. Common tells include:

- A test date in the future, or older than the product's stability window. - A peptide name that doesn't match the molecular formula or mass-spec section. - A retention time inconsistent with the peptide claimed (a quick literature search will indicate whether the value is plausible). - Logo / formatting that looks copy-pasted from a different lab's template. - Purity figures that round to suspiciously clean values without integration support (e.g. "99.0%" with no peak-area table to derive it from).

None of these are individually decisive, but a document that fails on multiple internal-consistency checks is almost always fabricated.

What a clean COA looks like

A clean Peptify Janoshik COA carries the lab name, the analysis date, the batch number, an HPLC chromatogram with peak integration, a purity figure derived from that integration, a mass-spectrometry trace, and the analyst's reference. The batch number on the document matches the lot number printed on the vial.

None of those elements are exotic. They are the bare structure of an analytical-chemistry report. Every research-grade supplier should meet this standard, and the absence of any element is a checkable, falsifiable signal that the document is not what it claims to be.

Research use only. No therapeutic framing.
