We aggregate 13,132 third-party lab tests covering HPLC purity, endotoxin levels, and quantity verification from independent laboratories. Every report is submitted by the community and verified before publication.
🔍 = this test's lab publishes a public COA verification portal you can check the result against.
High-Performance Liquid Chromatography (HPLC) is the gold standard for measuring peptide purity. It separates compounds in a sample and measures the percentage of the target peptide versus impurities. 98%+ is pharmaceutical grade; 95%+ is research grade.
Endotoxins are bacterial lipopolysaccharides that can cause fever and inflammation. The FDA limit for injectable products is 5 EU/kg body weight per hour. Results below 0.1 EU/mg are typically considered safe for research applications.
