Peptides World specializes in the synthesis of highly purified peptides, proteins and amino acid derivatives for scientific research and development. Peptide World uses automated and manual peptide synthesizers as well as solution and solid-phase peptide synthetic technology to offer the finest quality peptides and proteins that exceed 99% purity. From the initial stages of peptide synthesis to packaging and delivery, Peptides World implements the most strict quality control standards to ensure that all peptides arrive in their purest and most stable form. In house testing at all stages of production at our analytical test lab verifies our peptides sequential fingerprints for precision accuracy. This is achieved through highly accurate High-Performance Liquid Chromatography and Mass Spectrometry analysis, which scientifically proves the purity, accuracy and identity of each peptide.
