Quality & COAs

Third-Party Verification

All PepHQ, LLC products undergo rigorous third-party testing to verify purity, identity, and quality. Testing is performed in USA laboratories using advanced analytical methodologies including HPLC-UV-MS (High-Performance Liquid Chromatography with UV and Mass Spectrometry detection).

Purity Standards

We maintain strict purity standards of greater than 99% for all research peptides. Our testing protocols include both chemical purity analysis and chromatographic purity verification to ensure the highest quality compounds for laboratory research.

HPLC-UV-MS Testing Methodology

High-Performance Liquid Chromatography coupled with UV detection and Mass Spectrometry provides comprehensive analysis of peptide identity, purity, and composition. This advanced methodology allows for precise quantification and verification of molecular structure.

Certificates of Analysis

COAs are embedded directly in each product page for immediate access. These certificates include detailed analytical data such as purity percentages, actual amount, percent of label claim, CAS numbers, and identity confirmation via HPLC-UV-MS.

Storage Guidelines

Lyophilized peptides are stable at room temperature for several weeks when stored in a dry, sealed container away from light and moisture.

For extended storage, refrigeration (2-8°C) or freezing (-20°C) is recommended.
