We aggregate 8,891 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.
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.
Help the community by submitting your third-party lab test results. You'll need the original certificate from an accredited laboratory, details about the peptide and brand tested, and the testing date. All submissions are reviewed before publication.
