Red Flags & Scams
Educational only — not a buying guide
Many peptides are research-only or regulated; “research use only” labeling is NOT a legal shield. No vendors are endorsed here. See the Disclaimer and Terms & Conditions.
This page is a harm-reduction checklist of warning signs that a CoA, a seller, a product, or a payment request is not what it claims to be. None of this is a recommendation to buy anything — it exists so that people can recognize fabrication and fraud. Use it alongside How to Read a CoA, HPLC vs Mass Spec, and Third-Party Testing.
Top red flags — if you see these, stop
- No batch/lot number, or a batch number that doesn’t match the vial.
- No test date, or a test date before the manufacture date.
- Identical purity (e.g. “99.9%”) across many different, unrelated compounds.
- One CoA claimed to cover “all batches.”
- Verification QR/link that’s broken, or resolves to the seller’s own site instead of the lab’s.
- No mass spec — purity only, so identity is never confirmed.
- The “lab” is the seller, or the named lab doesn’t exist / can’t be found.
CoA red flags
- Suspiciously round numbers. Real instrument output has decimals and minor imperfections. Exactly
99.0%, exactly0.0impurities, and perfectly round molecular weights are fabrication signals. - No impurity peaks at all. Genuine syntheses leave small impurity peaks on the chromatogram. A perfectly flat trace with a single peak is implausible.
- Templated / generic appearance repeated across different peptides — same layout, same numbers, only the name swapped.
- Identical purity across lots, products, or months — a sign of a reused template rather than real per-batch testing.
- Missing chromatogram or spectrum — only summary numbers, no actual trace to inspect.
- No mass spec — purity reported but identity never confirmed (see HPLC vs Mass Spec).
- Missing lab name or contact info, or a lab that returns nothing on an independent search.
- Stripped identifiers — verification codes or QR codes removed or obscured.
- Mismatched reference — the verification code resolves to a different product or seller.
Vendor red flags
- Vendor is its own “lab.” Self-testing is not independent testing (see Third-Party Testing).
- Named third-party lab cannot be verified, or the lab has no record of the batch when checked on its own portal.
- Refuses to provide a batch number or a full, verifiable report.
- Reuses one CoA for everything, claiming it covers all batches.
- No way to independently confirm any quality claim.
Product red flags
- Prices far below comparable sellers (e.g. 40–60% lower) — under-dosed, mislabeled, contaminated, or counterfeit material is the usual explanation.
- Net peptide content never mentioned — only an HPLC purity figure, which hides how much actual peptide is in the vial (see How to Read a CoA and Reconstitution & Dosing Math).
- No storage / handling guidance, or claims that ignore degradation (see Storage & Handling).
- Implausible claims of sterility, potency, or fitness for a use that no report on file actually supports.
Payment red flags
- Only irreversible payment methods offered (e.g. crypto-only, wire, gift cards) with no recourse.
- Pressure tactics — countdown timers, “last batch,” urgency to pay off-platform.
- Requests to move off-platform to complete payment, away from any buyer protection.
- No coherent business identity behind the payment request.
How to act on a red flag
- Stop and verify the batch independently on the testing lab’s own portal, not a link the seller controls (see Third-Party Testing).
- Cross-check the vial’s batch number against the CoA and the lab record.
- Confirm both HPLC and MS are present (see HPLC vs Mass Spec).
- If anything fails to verify, treat the document as fabricated and the claim as unproven.
Remember: this is about recognizing fraud and fabrication. It does not make any compound safe, legal, or appropriate to use — see Regulatory & Legal Status and the Disclaimer.
