- CoA Purity Report
- 98.0–99.5% with decimal precision (e.g., 98.23%)
- Round numbers (99%, 95%) or vague claims ('>95%')
- Legitimate synthesis reports exact measured values. Suspiciously perfect round numbers indicate fabrication
- Mass Spectrometry Data
- 1682.98 Da ±0.5 Da with single dominant peak
- No mass spec data, or peak at incorrect molecular weight
- Mass spec is non-negotiable for identity confirmation. Absence signals either poor quality control or deliberate deception
- Chain of Custody
- Temperature logs, timestamped shipping records, facility registration
- No cold-chain documentation or generic storage claims
- Temperature excursions during shipping degrade peptides irreversibly. Lack of documentation means unknown quality regardless of synthesis origin
- Appearance After Reconstitution
- Clear, colourless solution within 60–90 seconds
- Cloudiness, precipitation, or difficulty dissolving
- Visual clarity is necessary but not sufficient. Counterfeit batches can appear identical using excipients to mimic solubility
- Third-Party Testing Availability
- Vendor provides batch samples for independent HPLC verification
- Vendor refuses or deflects independent testing requests
- Refusal to allow independent verification is the single clearest indicator of counterfeit or substandard product
- Price Positioning
- Within 15–25% of competitor pricing for equivalent purity
- 40–60% below market rate or suspiciously cheap
- Synthesis costs don't vary enough to support dramatic discounts. Extreme low pricing indicates corners cut somewhere in the supply chain
