Quality Assurance
Lab Testing & Certificates of Analysis
Every batch of PolyLabs research peptides is independently tested and verified. Transparency is the foundation of our quality commitment.
Our Testing Process
Independent Third-Party Verification
At PolyLabs Research, we believe that quality claims must be backed by independent verification. Every batch of peptides we produce is sent to an accredited third-party laboratory for comprehensive testing before it is released for sale.
HPLC Purity Analysis
High-Performance Liquid Chromatography (HPLC) is used to measure the purity of each peptide batch. We guarantee a minimum purity of 99%+ for all products.
Mass Spectrometry Confirmation
Mass spectrometry (MS) is used to confirm the molecular identity of each peptide, verifying the correct amino acid sequence and molecular weight.
Certificate of Analysis
A Certificate of Analysis (COA) is generated for each batch, documenting the testing results, lot number, and expiration date. COAs are available upon request.
