About PureSequence
PureSequence is a U.S.-based brand focused exclusively on supplying high-quality research peptides for qualified laboratories.
Established in the United States
We operate as a U.S.-based research supplier, with all products shipped from within the United States. Our focus is on supporting responsible in vitro and laboratory research, not consumer or clinical use.
High-purity peptides with clear documentation
Every peptide we list targets a purity of ≥98% and is matched to third-party analytical testing. Certificates of Analysis (COA) and batch-level details are linked directly from each product page so you can confirm specifications before ordering.
Testing and quality controls
Lots are reviewed against internal acceptance criteria and supported by independent laboratory analysis. Our goal is to give researchers confidence that each vial in a shipment is consistent with the data presented on the product page.
Shipping and research-only use
Orders are packed in sturdy, lab-ready materials and shipped from U.S. facilities using trusted couriers. All products are intended strictly for research and laboratory use only and are not for human or animal consumption or any medical application.
