At Pi Proteomics, LLC we manufacture all of our peptides in our own laboratory located in technology-rich Huntsville, Alabama.  We use only high quality raw materials (amino acids, resins and reagents), production machinery and quality control instrumentation.  Once you place a custom peptide order, you can monitor the progress of your peptides at your convenience via our web-based custom peptide status database, PepCheck.  When you order custom peptides from Pi Proteomics, the peptides delivered will meet or exceed your requirements. In order to show you our commitment to quality, we guarantee that all custom peptides meet your requirements or we will remanufacture your peptides at no cost to you.
