Quality & COAs

Our commitment to quality through rigorous third-party testing and verification.

Laboratory peptide testing

Testing Standards

Third-Party Verification

All PepHQ 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 and Handling

All peptides are stored under controlled conditions to maintain stability and integrity. Products should be stored at -20°C or below for long-term storage. Reconstituted peptides should be stored at 2-8°C and used within the recommended timeframe. Avoid repeated freeze-thaw cycles.

Our Quality Commitment

PepHQ is committed to providing research-grade peptides that meet the highest standards of quality and purity. Every batch is tested, verified, and documented to ensure consistency and reliability for laboratory research applications.

Note: Testing performed in USA laboratories. All analytical data verified by independent third-party testing facilities.
