- | Supplier | Synthesis Method | Purity Verification | Sequence Verification | Storage Protocol | Chain-of-Custody Documentation | Professional Assessment ||—|—|—|—|—|—|| Real Peptides | Small-batch SPPS, single-channel reactors | HPLC + mass spectrometry + third-party AA analysis | Full sequence verification via Edman degradation | −80°C until dispatch, cold-chain shipping with temp logging | Complete batch traceability from synthesis through delivery | Industry-leading verification at every stage. Reliability justifies the 15–20% premium over industrial suppliers || Generic Supplier A | Multi-channel industrial SPPS | HPLC only | Not performed | Standard refrigeration, ambient shipping with ice packs | Certificate of analysis only. No batch tracking | Purity numbers look solid, but lack of sequence verification means structural errors go undetected until assays fail || Generic Supplier B | Outsourced synthesis, variable sourcing | Vendor-provided COA | Not disclosed | Not specified |
