- cGMP-Certified Facilities (Real Peptides standard)
- Small-batch SPPS with preparative + analytical HPLC purification
- Third-party mass spec + HPLC for every batch; lot-specific COA published
- 98–99.5%+
- Full traceability from synthesis through shipping with documented storage
- Required standard for reproducible research—worth the cost difference for protocol integrity
- Research-Grade Suppliers (quality-focused, non-cGMP)
- SPPS with single-pass HPLC purification
- In-house HPLC; COA provided on request
- 95–98%
- Batch records maintained but not always accessible
- Acceptable for preliminary studies if COA verifies >97% purity and mass spec confirms sequence
- Bulk Suppliers (volume-focused)
- Large-batch synthesis with minimal purification
- Generic COA template; same document for multiple batches
- 85–95% claimed, often lower
- Limited or no batch tracking
- High risk—purity variance and contamination rates make results unreliable
- Unverified Online Sources
- Unknown or outsourced synthesis
- No documentation or COA unavailable
- Unverified; contamination common
- None
- Research protocol failure risk—underdosing, impurities, or wrong compound invalidate months of work
