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. Selank is studied in behavioral and neuroimmunology work where anxiety-like behavior, stress responses and immune parameters are measured in parallel, and its defined sequence keeps repeated-administration designs reproducible. The heptapeptide reconstitutes cleanly in physiological buffers, and protocols often run over one to two weeks. Our records document purity and content. Trial and bulk quantities are available with secure packing. Selank is filled in sealed vials with its batch record, and the lyophilized material reconstitutes cleanly for multi-day behavioral protocols. We can supply identical-lot vials for all treatment groups and coordinate staggered delivery that keeps the peptide within the recommended storage window throughout. Orders are processed promptly after confirmation, with professional packaging that protects lyophilized material during transit. We support both trial quantities for evaluation and bulk volumes for ongoing research programs, with dedicated after-sales assistance at every step.
