- Before choosing a supplier, researchers should compare synthesis oversight, testing transparency, and application support side by side. The table below maps key decision factors across both suppliers.
- Synthesis Method
- In-house SPPS with Fmoc chemistry, small-batch runs
- Third-party contract manufacturing, batch sizes vary
- Real Peptides maintains direct synthesis control; Paradigm relies on supplier protocols
- Purity Verification
- HPLC + ESI-MS for every batch, chromatograms provided
- COA from manufacturer, total purity percentage only
- Real Peptides offers sequence-level verification; Paradigm provides summary data
- Endotoxin Testing
- <1.0 EU/mg via LAL assay, tested per batch
- Not specified for most products
- Real Peptides suitable for cell culture; Paradigm lacks published endotoxin limits
- Third-Party Testing
- Independent lab verification, blind sample submission
- Manufacturer COA, no independent verification
- Real Peptides provides unbiased quality confirmation
- Cold Chain Shipping
- 2–8°C with insulated mailers, 48-hour thermal protection
- Ambient shipping for most lyophilised peptides
- Real Peptides reduces thermal degradation risk during transit
- Application Support
- Compound-specific reconstitution protocols, pH guidance
- General peptide handling instructions
- Real Peptides offers protocol-level detail for first-time users
- Regulatory Compliance
- cGMP facility operation, environmental monitoring
