Substance P is an 11-amino-acid tachykinin neuropeptide that acts preferentially at the neurokinin-1 receptor, mediating pain transmission, neurogenic inflammation and stress responses in experimental models. Its involvement in nociception makes it a reference compound in pain and inflammation research. The peptide is supplied as a white lyophilized powder at >=99% HPLC purity in a sealed vial. Batch-specific data and worldwide delivery are provided. Batch traceability is guaranteed through internal reference numbers, and retain samples are kept for post-shipment verification. Small trial orders are welcome alongside large contracts, and repeat customers enjoy tiered pricing and priority production slots for custom specifications. All export paperwork, including packing lists and commercial invoices, is prepared in English.
