| COAs & Lab Reports | All peptides offered by Northern Chems undergo strict quality-control procedures, including independent third-party analytical testing for purity, identity, and consistency. We use advanced testing methods such as HPLC (High-Performance Liquid Chromatography) and Mass Spectrometry to verify that each peptide meets the required research-grade standards. Every batch is tested before being released, and full Certificates of Analysis (COAs) can be provided upon request. This includes data on purity percentage, molecular confirmation, and batch identification. For the most up-to-date COAs and lab documentation, simply email us and our team will send the current testing reports for the specific peptide(s) you are interested in. We are committed to transparency, accuracy, and reliability—ensuring that researchers across Canada receive high-quality, fully verified peptide products every time. Note: Due to factors such as U.S. cross-border shipping delays, laboratory backlog, and the fact that we offer over 40 different products, it is not always possible to have up-to-date or readily available COAs for every batch. We always strive to provide them when possible, but please understand that COAs may not always be available immediately. |
