Understanding lab tests

01HPLC

What Is HPLC Purity Testing?

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.

02Endotoxins

Understanding Endotoxin Levels

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.

03Submit
