Certificates of Analysis (COAs)
At Seus Peptides, we are committed to providing the highest quality research materials. Transparency is the foundation of scientific trust, which is why we provide independent, third-party lab reports for every batch of peptides we sell. If you are comparing US suppliers, our guide to buying research peptides in the USA walks through what to require before you order.
Why Purity Verification Matters
Our peptides undergo rigorous testing using two primary methods to ensure they meet our strict quality standards:
- HPLC (High-Performance Liquid Chromatography): Confirms the purity of the peptide, ensuring it meets our minimum 98% purity standard.
- MS (Mass Spectrometry): Confirms the identity of the peptide by measuring its molecular weight.
