Advancing research through uncompromising quality and radical transparency.
PepLab.us was founded with a single objective: to provide the research community with peptides of the highest possible purity, backed by verifiable third-party testing. We believe that reliable results start with reliable reagents.
Every compound in our catalog undergoes rigorous quality control, including HPLC purity analysis and mass spectrometry identity confirmation, performed by independent laboratories. We publish these results openly because we believe transparency is the foundation of trust.
The research peptide market is crowded with suppliers making bold claims but offering little proof. We take a different approach. Every product we sell ships with a current Certificate of Analysis, and every COA is available for review on our website before you place an order.
Our synthesis and quality control processes are designed to meet or exceed industry standards. We work with experienced peptide chemists and maintain strict protocols for handling, storage, and fulfillment to ensure compound integrity from lab to delivery.
PepLab.us operates entirely within the United States. Our peptides are synthesized domestically, tested by US-based third-party laboratories, and shipped from our climate-controlled facility. This allows us to maintain full oversight of the supply chain and offer fast, reliable delivery to researchers nationwide.
All PepLab.us products are sold exclusively for in-vitro research and laboratory use. They are not intended for human or veterinary use, and are not to be used as food additives, drugs, or household chemicals. By purchasing from PepLab.us, customers agree to use all products in accordance with applicable laws and regulations.
