We are here to provide innovative solutions and custom services to further your in vivo research and developmental needs.

We personally guarantee the renowned quality of our products through multiple layers of quality control management. Every peptide undergoes Amino Acid Analysis to insure precise determination of weight and protein quantities. This provides us with detailed information on the relative amino acid composition and free amino acids. In turn, we are able to offer a proven-product you can truly have utmost confidence in. All Chemicals and Reagents undergo multiple forms of Mass Spectrometry to insure purity and that they are contaminant free. Unlike our competition, who only offer deceiving HPLC reports: at Peptides Warehouse we openly offer Full Spectrum testing through GC-MS in full scan electron ionization mode which defines a precise purity as well as even a trace amount of a contaminant. Furthermore, we also offer HPLC-MS using a photo diode array detector with simultaneous monitoring of wavelengths including electrospray ionization in both positive and negative ion modes. All of the aforementioned tests outline our stringent testing protocols prior to issuing a certificate of analysis.
