- | Supplier | Synthesis Method | Third-Party Verification | Stated Purity | Storage Conditions | Stability Data Provided | Professional Assessment ||—|—|—|—|—|—|| Real Peptides | Small-batch SPPS with coupling efficiency monitoring | Independent HPLC + MALDI-TOF mass spec at every batch | 99.5%+ | Nitrogen-purged lyophilization, −20°C | Batch-level stability curves at 0, 6, 12, 24 months | The only supplier in this comparison with independent sequence verification at every production run. Eliminates the risk of amino acid substitution errors that reduce receptor binding || Generic Supplier A | Bulk SPPS synthesis | Manufacturer certificate only | 98% | Standard lyophilization, ambient storage | None provided | No independent confirmation of sequence fidelity. Stated purity based on manufacturer's internal testing, which frequently overstates actual purity by 5–10% when re-tested independently || Generic Supplier B | Contract synthesis (outsourced) | Certificate of analysis from contract
