- Before selecting a supplier, compare verification protocols, cold-chain handling, batch traceability, and published test results. The table below summarizes the key differentiators among research-grade peptide suppliers active in 2026.
- Real Peptides
- LC-MS + amino-acid analysis + HPLC (independent lab)
- >98% verified per batch
- −20°C storage, gel ice shipping, temp loggers
- Batch-specific CoAs published on product pages
- Only supplier offering full structural verification on every Dihexa batch with published results
- Generic Research Supplier A
- HPLC only (manufacturer CoA)
- >95% claimed
- Room temp shipping, no cold-chain
- Generic CoA reused across batches
- Purity verified but structural integrity unconfirmed. High risk for inactive analogs
- Budget Peptide Vendor B
- No independent testing
- Not disclosed
- Standard mail shipping
- No batch documentation
- Lowest cost but no verification. Suitable only for preliminary non-critical studies
- Premium Nootropics Supplier C
- HPLC + LC-MS (in-house)
- >98% verified
- Refrigerated shipping on request
- Batch numbers provided, CoAs available on request
- Structural testing conducted but not independent. Moderate confidence level
