Our Commitment to Quality
Every peptide we offer undergoes a multi-step quality assurance process. Starting with solid-phase peptide synthesis (SPPS) in controlled US-based laboratories, each compound is purified using reverse-phase HPLC and verified through electrospray ionization mass spectrometry (ESI-MS).
We provide a Certificate of Analysis (COA) with every shipment, documenting purity percentages, molecular weight confirmation, and batch-specific data. Our commitment extends beyond the product — we offer technical support to help researchers with reconstitution protocols and storage guidelines.
All products are sold strictly for in-vitro research and laboratory use. We maintain full compliance with applicable regulations and require purchasers to confirm their intended research use.
