HPLC (high-performance liquid chromatography) instrument used to verify Certified Aminos peptide purity for each batch's Certificate of Analysis

About our testing methodology

Every raw material we receive undergoes rigorous High-Performance Liquid Chromatography (HPLC) prior to compounding. This analytical technique separates, identifies, and quantifies each component in a mixture, ensuring absolute sequence accuracy.

Following synthesis and lyophilization, random samples from the finished batch are submitted to independent third-party laboratories. They perform secondary HPLC alongside Mass Spectrometry (MS) to verify that the molecular weight perfectly matches the target peptide structure and that purity exceeds our 99% baseline standard.

Demanding a higher standard
