Peptide Sciences™ specializes in the synthesis of highly purified peptides, proteins and amino acid derivatives for scientific research and development. Our laboratory utilizes both automated and manual peptide synthesizers alongside advanced solution and solid-phase peptide synthetic technologies to deliver superior-quality peptides and proteins that exceed 99% purity.

From the initial stages of peptide synthesis to packaging and final delivery, our company enforces the most stringent quality control standards to ensure that every peptide arrives in its purest and most stable form.

Comprehensive testing at all stages of production within our analytical laboratory verifies each peptide’s sequential fingerprint for precision accuracy. Using advanced High-Performance Liquid Chromatography (HPLC) and Mass Spectrometry analysis, we scientifically confirm the purity, identity, and accuracy of every peptide produced.
