10 mg Selank | 15 mL Sterile Saline | Approximately 67 mcg per Metered Spray*
Our Selank Nasal Spray contains 10 mg of Selank (Thr-Lys-Pro-Arg-Pro-Gly-Pro) formulated in 15 mL of sterile isotonic saline for convenient intranasal administration. Each metered spray delivers a consistent amount of peptide to support precise dosing.
Selank is a synthetic heptapeptide derived from tuftsin, a naturally occurring immunomodulatory peptide. It was developed by researchers at the Russian Academy of Sciences to improve the stability and biological activity of tuftsin and has been investigated for its effects on stress regulation, cognitive function, and neurochemical signaling. It is approved as a prescription medication for certain indications in Russia but is not approved by the U.S. FDA.
Scientific Background
Intranasal Selank has been studied for its influence on several neurological and immunological pathways. Research suggests Selank may:
Modulate GABAergic neurotransmission, a key system involved in stress and anxiety regulation.
Influence serotonergic and dopaminergic signaling.
Support expression of neurotrophic factors such as brain-derived neurotrophic factor (BDNF) in experimental models.
Affect cytokine signaling and immune system regulation.
Promote neuroplasticity and adaptive responses to stress in preclinical studies.
Areas of Research
Selank has been investigated in research involving:
Stress response
Anxiety-related disorders
Cognitive performance
Learning and memory
Attention and mental clarity
Neuroprotection
Immune modulation
While published studies—primarily from Russia—have reported promising findings, larger, independently replicated clinical trials are needed to confirm efficacy and establish long-term safety across these applications.
