Selank Nasal Spray

Selank is a synthetic heptapeptide analogue of tuftsin, an endogenous immunopeptide associated with immune and neurological signaling. In non-human research models, this compound is studied in relation to GABAergic pathway modulation, BDNF expression, and neuroregulatory peptide behavior under varied environmental conditions.

Research applications commonly explored in the literature include:

GABAergic and anxiolytic-associated signaling pathway investigation in non-human models

Neurotrophic factor expression research, including BDNF and related signaling mediators

Tuftsin-analogue receptor interaction and comparative activity studies

Neuropeptide behavior modeling under acute and sustained stress-condition protocols in non-human systems

Comparative neuropeptide signaling studies alongside ACTH-derived and delta-sleep peptide analogues

The nasal spray format supports investigation of intranasal delivery as an administration route for centrally-acting peptides in non-human research models, enabling comparative analysis of peptide bioavailability and CNS-pathway accessibility across delivery methods. Each bottle of Selank Nasal Spray is manufactured in the United States and independently verified by third-party laboratories for purity, concentration accuracy, and molecular identity.

1. Why is Selank studied in nasal spray format?
Intranasal delivery enables comparative research into peptide bioavailability and CNS-pathway accessibility across administration routes in non-human models. Scientific literature examines whether delivery method influences peptide behavior and downstream signaling outcomes within centrally-acting neuropeptide research frameworks.

2. Is Selank intended for anxiety, focus, or therapeutic outcomes?
No. This product is for research use only. It is not intended for human or animal use, or for any therapeutic application.

3. How long does the product remain stable after opening?
Store in a refrigerator between 2–8°C and use within 30 days to preserve stability and sterility.

4. Can Selank be studied alongside other peptides?
Selank appears in scientific literature alongside Semax and DSIP in multi-peptide non-human research models examining overlapping neuroregulatory and neuropeptide signaling pathways. Researchers should reference peer-reviewed literature to validate study design and compound combinations appropriate to their specific research framework.

5. Where is Selank Nasal Spray produced?
All KÖLD nasal sprays are formulated, filled, and tested in the United States under sterile laboratory conditions. Each batch is independently verified by third-party laboratories for concentration accuracy, molecular identity, and sterility prior to release.

Store in the refrigerator at 2–8°C (36–46°F)
