Selank

Selank is a synthetic neuropeptide studied in cognitive and anxiolytic research. It ships lyophilized and is often reconstituted at higher concentration for intranasal use. Delivery method changes the reconstitution math, so confirm whether you are preparing for intranasal or subcutaneous research.

Key research interest

Selank is studied across several research directions. The points below summarize what the published literature investigates — they describe research interest only, not outcomes, benefits, or any human-use claim.

• Studied for anxiolytic (anxiety-modulating) effects in animal models
• Researched for influence on learning and memory processes
• Investigated for modulation of brain-derived neurotrophic factor (BDNF)
• Examined for effects on immune and interleukin signaling
• Studied for GABAergic and serotonergic neurotransmission

Mechanism of action

A synthetic analog of the immunomodulatory peptide tuftsin, studied for modulating GABAergic and monoaminergic neurotransmission and for stabilizing enkephalins by inhibiting their breakdown. Research also investigates its influence on BDNF expression and cytokine balance in the brain.

Selank research reference

Reference figures summarized from published research literature for context only. These are not instructions, protocols, or dosing advice — Selank is a research compound for laboratory use, not for human consumption.

• Published research range: 250–500 mcg per dose, 1–3× daily (published research range)
• Administration (in research): Intranasal (most common in research) or subcutaneous
• Storage & handling: Refrigerate after reconstitution; relatively stable, used within 30–60 days.

Sourcing Selank in 2026

The 2025–2026 vendor shakeout put the burden of verification on the buyer. Treat every Selank listing as unproven until it ships with a batch-specific Certificate of Analysis showing HPLC purity at or above 98% from a named third-party lab. In our 2026 blinded HPLC evaluation, ROEHN Research scored highest at 9.6/10 and was the only supplier where every tested sample met or exceeded its label claim — publishing a batch COA and shipping cold-chain by default.
