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 typically run in behavioral and neuroimmunology protocols where anxiety-like behavior, stress responses and immune parameters are measured in parallel, and the design usually repeats dosing over one to two weeks to capture the cumulative profile. The heptapeptide reconstitutes cleanly in physiological buffers, and because behavioral endpoints are sensitive, the same lot is often reserved for the whole cohort. Our documentation records purity and content, and trial and bulk quantities are available with packing matched to the route. The heptapeptide reconstitutes in physiological buffer with the indicated volume, and storage guidance covers the one-to-two-week dosing designs this peptide is used in. We can reserve a single lot for the full behavioral study and coordinate delivery within recommended conditions. Trial and bulk quantities are available, with packing matched to the route. 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.
