- This table compares synthesis oversight, testing protocols, and operational focus between Real Peptides and Peptide Sciences based on publicly available information and documented quality control standards as of 2026.
- Batch Size
- Small-batch synthesis (50–200 vials per run)
- High-volume production (500–1,000+ vials per run)
- Smaller batches allow earlier contamination detection but slower restocking
- Third-Party Testing
- Every batch verified by independent HPLC before shipment
- Sample-based third-party testing with full verification for flagged batches
- Continuous verification eliminates statistical sampling risk
- Traceability
- Lot numbers assigned at synthesis stage with full reagent tracking
- Lot numbers assigned post-packaging
- Synthesis-level traceability supports root-cause analysis for anomalies
- Catalog Breadth
- 60+ peptides with focus on emerging research compounds
- 100+ peptides across metabolic, cosmetic, and research categories
- Peptide Sciences offers wider immediate selection
- Custom Synthesis Minimums
- 50mg minimum order, 4–6 week lead time
- 100mg minimum order, 6–8 week lead time
- Real Peptides better for exploratory small-batch custom work
- Customer Support Response
- Under 12 hours for technical inquiries, direct phone access
- 24–48 hours via ticket system, extensive knowledge base
- Real Peptides better for troubleshooting, Peptide Sciences better for self-service
- Documentation Transparency
- Full synthesis pathway details provided on request
- Standard certificates of analysis, synthesis methods proprietary
- Real Peptides supports reproducibility documentation for publication
- Cost Per Milligram (Average)
- $8–$12/mg for common peptides, higher for specialized compounds
- $6–$10/mg for high-volume peptides, competitive on standard inventory
- Peptide Sciences lower on cost, Real Peptides competitive on risk-adjusted value
