Selank
Anxiolytic Heptapeptide
Synthetic analogue of the endogenous tetrapeptide tuftsin (Thr-Lys-Pro-Arg) extended with Pro-Gly-Pro. Studied for GABAergic tone modulation, anxiolytic effects without tolerance development, and improvement of verbal memory under stress.

Research Dose
250–500 mcg
Frequency
1–3× daily

2–4 weeks
Half-Life
~2 minutes (serum), but metabolites active for longer
Route(s)
Intranasal · Subcutaneous
Solubility
Water, saline
Reconstitution
Dissolve in sterile 0.9% saline for intranasal; bacteriostatic water for subcutaneous research.
Key Research Findings
Tuftsin-derived — endogenous origin may contribute to the absence of dependence or withdrawal in research models.
Modulates enkephalinase activity, extending endogenous opioid peptide half-life.
Increases IL-6 and interferon gamma production — potential immune modulating research applications beyond CNS.
Administration Reference
Intranasal route provides direct access to the olfactory-CNS pathway. Research protocols typically use 1–3 daily administrations across 2–4 week observation periods. Subcutaneous injection in the abdominal region is documented as an alternative route.
Documented Combination Protocols
Cognitive + anxiolytic stack: Selank modulates anxiety, Semax drives BDNF and cognitive enhancement.
Dual anxiolytic + antidepressant research model — TREK-1 and GABAergic pathways combined.
