- Before selecting a supplier, compare the depth and transparency of their third-party verification. The table below contrasts the analytical standards across supplier categories based on publicly available documentation.
- Unverified suppliers
- Supplier-generated HPLC or none
- Rarely confirmed via MS
- Not disclosed
- Generic templates, no batch specificity
- Full batch-specific COA with independent lab stamps
- 'In-house tested' suppliers
- Internal HPLC
- Claimed but not independently verified
- Sometimes included
- Available on request, no third-party lab named
- ISO 17025-accredited lab verification for every batch
- Third-party tested suppliers
- Independent RP-HPLC
- ESI-MS confirmation within ±0.5 Da
- LAL assay <1.0 EU/mg
- Publicly downloadable, lot-specific
- Exceeds standard. Amino acid sequencing + MS + HPLC + endotoxin
- Research-grade verified suppliers
- RP-HPLC + amino acid analysis
- Full sequence confirmation + mass spec
- USP <71> sterility + endotoxin
- Full analytical data with equipment calibration records
- Real Peptides meets this tier with transparent chain of custody
- The critical differentiator is whether the supplier names the independent laboratory, provides the lab's ISO accreditation number, and makes full chromatograms and mass spectra available for researcher review. Suppliers that provide only purity percentages without underlying data are not offering verifiable third-party testing. They're offering claims.
