Peptide Sciences is a USA-based research peptide supplier producing highly purified peptides, proteins, and amino-acid derivatives for in-vitro and preclinical research. Every compound is synthesized using solid-phase peptide synthesis (SPPS), purified by reverse-phase HPLC, and identity-confirmed by ESI-MS / MALDI-TOF mass spectrometry. From synthesis through lyophilisation, sealing, and cold-chain dispatch, each batch is quality-controlled to a verified ≥99% HPLC purity and ships with a batch-specific Certificate of Analysis — the chromatogram, not just the number. This is the standard 14,000+ research laboratories rely on.
