Selank is a synthetic heptapeptide with the sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro, developed from the tuftsin family and studied in neuropharmacology and stress-related research. It is supplied as a high-purity white lyophilized powder, >=99% by HPLC, in sealed vials for laboratory use. Selank is investigated in research on anxiety regulation, stress response, emotional stability and neuropeptide signaling, and is commonly applied in cell-based and preclinical neuroscience studies. The lyophilized format ensures high stability and easy reconstitution for reproducible experimental dosing. Strict quality control is applied to every batch, and COA is available for specific batches on request. Keep the unopened product sealed at 2-8 degree C away from light; -20 degree C is recommended for long-term storage avoiding repeated freeze-thaw cycles. Small and bulk orders are both welcome, and OEM and discreet neutral packing are offered. The heptapeptide is studied in behavioral and neuroimmunology protocols where anxiety-like behavior, stress responses and immune parameters are assessed in parallel, and investigators value its defined sequence for reproducible dosing. Its lyophilized form reconstitutes cleanly in physiological buffers, and the product is compatible with repeated-administration designs common in behavioral pharmacology. Quality documentation, storage guidance and flexible ordering options are provided with each shipment. Behavioral pharmacology protocols typically involve repeated daily dosing over one to two weeks, with anxiety-like behavior, locomotion and immune parameters measured at scheduled points, so a peptide that reconstitutes reliably is essential for consistent group comparisons. The heptapeptide is also used alongside other regulatory peptides in neuroimmunology programs, and our team can arrange combined orders with matched documentation. Every shipment includes purity verification and storage recommendations, and we support both small pilot quantities and bulk supply for extended studies. Questions about specifications, packing or delivery are answered promptly before and after ordering. All products are manufactured under controlled conditions and released only after purity verification. We welcome small and large orders alike, provide professional packing and fast worldwide dispatch, and offer steady supply to research institutions, labs and trading partners.
