- This table compares Real Peptides against typical competitor practices across the quality factors that actually affect experimental outcomes.
- Synthesis Method
- Small-batch SPPS with real-time coupling efficiency monitoring
- Bulk liquid-phase synthesis or automated SPPS without per-step verification
- SPPS with coupling verification produces fewer deletion sequences and higher sequence fidelity
- Third-Party COA
- Published Janoshik COAs for every batch. HPLC purity, MS verification, residual solvent testing
- In-house testing only, or third-party COAs 'available upon request' (often missing)
- Independent third-party verification eliminates conflict of interest and proves claimed purity
- Purity Standard
- ≥98% verified by external HPLC
- Claims of 98–99% without third-party verification, or no published purity data
- Without third-party HPLC, purity claims are unverifiable marketing statements
- Storage Protocol
- −20°C desiccated storage; cold-pack insulated shipping with 48-hour cold-chain rating
- Room-temperature storage; standard ground shipping with no temperature control
- Temperature excursions during shipping cause degradation that visual inspection won't detect
- Sequence Verification
- Mass spectrometry confirmation of molecular weight (160.18 g/mol) on every batch
- Mass spec data not published or only provided selectively
- MS confirmation is the only way to verify you received 5-Amino-1MQ and not a substitute compound
- Reconstitution Guidance
- Bacteriostatic water; refrigerate 2–8°C; use within 28 days; never freeze solutions
- Vague or missing reconstitution instructions; some recommend freezing (incorrect)
- Freezing reconstituted peptides causes structural damage. Proper guidance matters
