- Real Peptides
- SPPS with Kaiser monitoring, controlled TFA cleavage
- Independent HPLC + mass spec on every batch
- 98.2–99.6%
- Full chromatogram, molecular weight, impurity profile provided
- $135–$160
- Gold standard for reproducible research—worth the premium when protocol success depends on compound fidelity
- Mid-Tier Verified Suppliers
- Standard SPPS, generic cleavage protocols
- Periodic third-party testing, batch-specific CoA available on request
- 95–98%
- Purity certificate without chromatogram
- $85–$120
- Acceptable for preliminary work where minor impurities won't confound interpretation
- Budget Suppliers
- Automated synthesis, no coupling verification
- In-house UV spec or no verification
- 85–95% (often undocumented)
- Generic purity claim, no batch traceability
- $45–$65
- High risk for protocol failure—impurities often include active analogs that skew results unpredictably
