Selank — sometimes referred to as TP-7 — is a research peptide that appears often in neurological and behavioral research literature. This overview explains what Selank is, why it's studied, and what to look for when sourcing it for laboratory research.

What Selank Is

Selank is a synthetic peptide developed as an analog of a naturally occurring peptide called tuftsin. It is classified in research as a neuropeptide and is studied for how it interacts with pathways in the nervous system. In research settings, Selank is commonly supplied as a lyophilized vial or as a pre-mixed nasal spray (often labeled "Selank TP-7").

Why Researchers Study It

Selank appears across published preclinical and laboratory research examining anxiety-related pathways, cognition, and immune-signaling mechanisms. Its stability and well-characterized sequence make it a common reference compound in neuropeptide research. This research is conducted in laboratory and animal models — Selank is not approved for human use and is supplied strictly for research purposes.

How Research-Grade Selank Is Tested

For research, purity and identity are what matter most. Research-grade Selank should be:

• Synthesized and lyophilized in a controlled facility (Helio's compounds are made in the USA).
• Batch produced and batch tested.
• Purity-verified by HPLC — look for 99%+.
• Identity-confirmed by mass spectrometry.
• Accompanied by a batch-specific Certificate of Analysis (COA).

Selank vs Semax — A Quick Note

Selank is frequently compared with Semax, another research neuropeptide often supplied as a nasal spray. Both are short synthetic peptides used in nervous-system research, but they derive from different parent sequences and are studied for different pathways. We cover the full comparison in a separate article.

Key Takeaways

• Selank (TP-7) is a synthetic neuropeptide studied in neurological and behavioral research.
• It is commonly supplied as a nasal spray or lyophilized vial.
• For research, insist on 99%+ purity, HPLC + mass-spec testing, and a batch COA.
• It is intended for laboratory research use only.
