B7-33 is a synthetic peptide derived from the B-chain of human relaxin that acts as an RXFP1 receptor agonist, activating relaxin-family signaling pathways involved in fibrosis resolution, vasodilation and organ-protective responses. Its defined agonist profile makes it a useful probe in cardiac, renal and fibrotic disease research. The peptide is delivered as a white lyophilized powder at verified HPLC purity in sealed vials, with quality records available for each production batch. Each batch is released only after peptide-content verification and purity assessment, and the corresponding records are retained for future reference. For projects requiring independent confirmation, we can arrange third-party analytical testing and share the results before shipment on request.
