- Purity (HPLC)
- ≥98% verified
- 90–95% claimed (no COA)
- 85–92% estimated
- Real Peptides meets pharmaceutical-grade threshold; competitors rely on in-house estimates
- Sequence Verification
- MS confirmed on every batch
- HPLC only
- Not disclosed
- MS is the only method that confirms amino-acid sequence accuracy
- Third-Party COA
- Published per batch
- Available on request
- Not provided
- Independent validation eliminates self-reporting bias
- Synthesis Method
- Microwave-assisted SPPS
- Standard SPPS
- Liquid-phase (lower fidelity)
- Microwave SPPS reduces racemization and improves coupling efficiency
- Storage Format
- Lyophilized + desiccant, −20°C recommended
- Lyophilized, no desiccant
- Powder in ambient packaging
- Desiccant prevents humidity-driven degradation during shipping
- Price per mg
- Premium (~$180/5mg)
- Mid-range (~$110/5mg)
- Budget (~$65/5mg)
- Price correlates directly with purification rigor and COA verification
