Selank Peptide Liquid Spray (45mg) for Laboratory Research

Q: Where can Selank be purchased for research in the USA?

Selank is available for sale directly from Real Peptides, a US chemical supplier serving laboratory and research buyers. Orders are placed online and fulfilled from facilities in Florida and California. Buyers confirm at checkout that they are 21 or older and that the material is being acquired strictly for laboratory research use, not for human or animal use.

Q: How is the price for this Selank listing determined?

Pricing for Selank is shown on this product page and reflects the format and quantity supplied, in this case the 45mg liquid spray. Figures are not quoted in this FAQ because catalog pricing is periodically updated. The current amount, along with any quantity-based options, always appears in the purchase panel above.

Q: Is a certificate of analysis published for this Selank lot?

Yes. Each batch of Selank is submitted to an independent analytical laboratory, and the certificate of analysis for the exact lot in stock is published in the lab results section of the site. The COA can be reviewed before purchase and typically reports identity by mass spectrometry and purity by HPLC for that specific lot.

Q: How is Selank purity verified?

Purity is measured by an outside laboratory rather than in-house, using HPLC for purity and mass spectrometry for identity confirmation. The reported figure for the lot currently in stock appears on its published certificate of analysis. Real Peptides does not sell material that has not cleared independent batch testing and had its report posted.

Q: What format and size does this Selank listing supply?

This listing supplies Selank as a pre-solubilized liquid spray in a 45mg size, sometimes searched for as a nasal spray format. The peptide is already in solution, so no separate reconstitution step is required in the laboratory. Only this format and size are covered by this page; other presentations, if stocked, appear on their own catalog pages.

Q: Does Real Peptides ship Selank to Texas and other states?

Yes. Selank ships nationwide within the United States, including Texas, from stocking facilities in Florida and California. Orders placed on business days are dispatched within 24 hours. Tracking is issued once the parcel leaves the facility, and packaging is discreet and labeled for laboratory research materials.

Q: How should Selank be stored when it arrives at the lab?

As a solution, Selank is generally kept refrigerated, protected from light, and tightly capped between laboratory uses. Prolonged exposure to heat, freeze-thaw cycling, and direct sunlight should be avoided. Laboratories set their own handling protocols; storage guidance here is descriptive of general peptide practice and not an instruction for any other use.

Q: What should researchers look for in a Selank peptide supplier?

A credible Selank vendor tests every batch through an independent laboratory, publishes the certificate of analysis for the specific lot being sold rather than a generic sample document, ships from domestic stock with tracking, and states clearly that the compound is a research chemical, not a drug or supplement, with no approval for human or animal use.

Selank is a synthetic heptapeptide (Thr-Lys-Pro-Arg-Pro-Gly-Pro) derived from the endogenous immunomodulatory peptide tuftsin. It was developed in Russia and is used in laboratory and preclinical literature as a reference compound in studies of neuropeptide and immune signaling pathways.

Real Peptides supplies Selank as a pre-solubilized liquid spray in a 45mg size. Every batch is assayed by an independent analytical laboratory, and the certificate of analysis for the current lot is published in the lab results section so it can be reviewed before purchase. Orders ship from US facilities in Florida and California within 24 hours. This material is sold strictly for laboratory research use and is not a drug, supplement, or cosmetic.

What Is Selank Peptide?

Selank is a synthetic seven-amino-acid peptide (Thr-Lys-Pro-Arg-Pro-Gly-Pro) derived from tuftsin, a natural fragment of human immunoglobulin G. Developed at the Russian Academy of Sciences, Selank is studied in preclinical and clinical research for anxiolytic, cognitive, and immunomodulatory activity. It acts on GABAergic, serotonergic, noradrenergic, and enkephalin pathways, giving researchers a multi-system tool for studying anxiety, cognition, and neuroimmune crosstalk — all without the sedation profile of benzodiazepine-class compounds.

Why Choose Selank Liquid Spray?

Researchers choose Selank liquid spray when they need a precise tool for studying anxiety pathways, cognitive resilience, and neuroimmune modulation. The intranasal format delivers Selank through the olfactory and trigeminal pathways — a direct route to the central nervous system that bypasses first-pass metabolism entirely. and HPLC-verified at ≥99% purity with endotoxin <0.1 EU/mg, Real Peptides Selank delivers reproducible, high-fidelity data across behavioral, electrophysiological, and neurochemical research models.

What Sets Selank Apart?

Unlike benzodiazepine-class compounds, Selank engages GABA pathways through allosteric modulation rather than direct receptor agonism — meaning it can produce anxiolytic-like effects in research models without the hallmarks of sedation, dependence, or withdrawal. Its dual identity as both an anxiolytic and an immunomodulator makes Selank uniquely versatile: one peptide, studied across anxiety, cognition, and immune research. That’s why researchers frequently pair Selank with Semax liquid spray for combined cognitive-anxiolytic research designs.

Research observations

Anxiolytic Activity Modeling

In rodent anxiety assays, Selank produces anxiolytic effects comparable to benzodiazepines without the sedation, dependence, or withdrawal markers characteristic of that drug class.

BDNF & Hippocampal

Selank rapidly elevates brain-derived neurotrophic factor (BDNF) expression in the hippocampus, making it a research tool for neuroplasticity and memory studies.

GABAergic Modulation

Selank allosterically modulates GABA-A receptor activity in neuronal assays — binding without directly agonizing the receptor, which distinguishes it from classical anxiolytics.

Serotonin, Dopamine & Noradrenaline Pathways

Selank influences monoamine metabolism in preclinical models, making it relevant for mood, attention, and cognitive research.

Immunomodulatory Signaling

As a tuftsin analog, Selank modulates IL-6 expression and Th1/Th2 cytokine balance, bridging neuroscience and immunology research.

Lab-Friendly Format

Pre-formulated liquid spray — no reconstitution required. Store at 2–8°C, protect from light. Maintains ≥98% integrity throughout shelf life.
