Protect yourself from peptide scams.
The research-peptide market is unregulated. Underdosed vials, fake certificates of analysis and outright scams are common. Education is your best defence — here's how to verify before you ever buy.
How to verify a COA
A certificate of analysis is only useful if it's real and tied to your batch.
Match the compound
The COA must name the exact peptide and show it matches by mass spectrometry (MS).
Check the purity
Look for HPLC purity (ideally ≥98%) on the specific batch you're buying — not a generic sample.
Verify the lab
A real third-party lab is named and reachable. Contact them to confirm the report is genuine.
Tie it to the batch
The batch/lot number on the COA should match the vial you receive.
Red flags to walk away from
- ✕No batch-specific COA, or a COA that won't scan / can't be verified with the lab
- ✕Prices far below every other seller for the same peptide and size
- ✕Pressure tactics, crypto-only payment, or no business address
- ✕Reused stock photos and vague 'research only' claims with no testing data
- ✕Purity or mass-spec results that don't match the labelled compound
