MADE IN THE USA
At The Peptide Daddy, every research peptide undergoes rigorous multi-stage quality testing to ensure the highest standards of purity and reliability. Each batch is analyzed multiple times using High-Performance Liquid Chromatography (HPLC) for purity (typically ≥98.5–99.5%), Mass Spectrometry (MS) for molecular identity confirmation, and third-party independent laboratory verification. We also perform endotoxin testing and sterility assessments to meet the stringent requirements of scientific research. Batch-specific Certificates of Analysis (COAs) with full chromatograms and test results are available with every order.
