Selank is a synthetic heptapeptide based on the tuftsin sequence with a threonine-lysine-proline-arginine-proline-glycine-proline structure, investigated for anxiolytic, immunomodulatory and cognitive effects in animal models. Its dual influence on anxiety behavior and immune parameters distinguishes it in neuropeptide research. The material is a white lyophilized powder at >=99% HPLC purity in a sealed vial. We offer batch documentation, flexible pack sizes and fast international delivery for research programs. For many groups, this anxiolytic heptapeptide enters the workflow because its short, well-defined sequence makes repeated behavioral testing reproducible, and investigators use it when anxiety and stress readouts need a consistent tool. Researchers tend to reach for it in protocols that combine behavioral scoring with neuroimmune markers. The value often comes down to the peptide's stability under standard storage and easy preparation. We supply it with HPLC-verified purity, matched vials are available for multi-arm designs, and delivery is arranged so the powder reaches the lab in good condition. Delivery of this anxiolytic heptapeptide is organized within recommended conditions, and the parcel carries the purity report and handling notes. Multi-arm behavioral designs can reserve matched vials from one lot, with packing selected according to the route. Trial and bulk quantities are both available. With a stable supply chain and strict quality control, we serve research teams and distributors in many countries. Every parcel is professionally packed and tracked, and we provide timely communication from order to delivery, plus after-sales support.
