- Real Peptides
- Small-batch SPPS with intermediate checkpoints every 5 residues
- HPLC + mass spectrometry on every batch
- Molecular weight confirmed ±0.5 Da
- Lyophilized powder, −20°C with temperature indicators
- LAL assay <1 EU/mg certified
- Gold standard for research applications requiring verified molecular structure and traceable quality documentation
- Research-Grade Competitor A
- Automated SPPS, no intermediate monitoring
- HPLC only, mass spec on request
- Not routinely confirmed
- Lyophilized powder, storage conditions unspecified
- Not disclosed
- Acceptable purity but lacks structural verification—higher risk of deletion sequences
- Bulk Supplier B
- Large-batch automated synthesis
- HPLC from pooled batches
- No mass spec available
- Pre-mixed solution or lyophilized without preservatives
- Not performed
- Significant quality variance between batches, unsuitable for reproducible research
- Generic Online Vendor
- Synthesis location undisclosed
- CoA provided but methodology unclear
- Unknown
- Variable—often pre-mixed
- Unverifiable quality, high contamination risk, frequent shipping temperature failures
