Quality Assurance & Certificates of Analysis
Every peptide we sell is independently tested — transparency and purity are non-negotiable
Our Commitment to Quality
Quality is the foundation of everything we do. Every batch of research peptides undergoes rigorous third-party laboratory testing before it reaches your lab. We publish full certificates of analysis (COA) for complete transparency — because researchers deserve to know exactly what they're working with.
Testing Methodology
Each peptide is analyzed using industry-standard analytical methods:
- High-Performance Liquid Chromatography (HPLC): Confirms peptide purity to ≥98–99% for every batch.
- Mass Spectrometry (MS): Verifies molecular weight and structural identity of each compound.
- Endotoxin Testing (LAL): Ensures products meet acceptable endotoxin levels for research applications.
- Sterility Testing: Bacteriostatic water and reconstitution supplies undergo sterility verification.
Third-Party Independence
All testing is performed by accredited, independent analytical laboratories — never in-house. This ensures unbiased, verifiable results that you can trust for your research. Our testing partners hold ISO 17025 accreditation and follow GLP (Good Laboratory Practice) standards.
What Each COA Includes
- Product name and batch/lot number
- Purity percentage (HPLC)
- Molecular weight confirmation (MS)
- Appearance and physical description
- Date of analysis and expiration
- Laboratory name and analyst signature
