Selank Peptide Therapy

SELANK is a research peptide derived from a synthetic analogue of the human tuftsin molecule, a naturally occurring immunomodulatory peptide. It’s explored for its anxiolytic, nootropic, and neuroprotective potential—supporting stress resilience, cognitive function, and mood regulation. At The Catalyst Clinic, SELANK is considered only within a physician-led programme with appropriate screening and follow-up.

What is SELANK?

SELANK is a synthetic heptapeptide (Thr-Lys-Pro-Arg-Pro-Gly-Pro) engineered to mimic and enhance the effects of tuftsin, but with greater stability and a broader range of neuropsychological effects. Like SEMAX, it is typically delivered intranasally due to poor oral bioavailability. Developed in Russia, SELANK has been used in clinical contexts there, but high-quality, English-language human data remain limited.

Neurochemical Modulation

Preclinical research suggests SELANK can modulate the balance of neurotransmitters, particularly serotonin and dopamine, which are closely linked to mood, anxiety, and cognitive performance. SELANK may also influence the expression of genes involved in the stress response and immune regulation.

Cognitive and Anxiolytic Effects

Animal studies indicate SELANK improves sensory attention, learning processes, and investigative activity. It has shown promise in normalizing behavior in models of stress and anxiety, and may help facilitate learning and memory formation.

In Plain Terms

SELANK may help the brain and body adapt to stress, support cognitive performance, and promote a balanced mood by influencing neurotransmitter systems and immune signaling. Evidence in healthy adults and patients is still developing, and its use should be guided by medical professionals.

How Selank Works

Selank interacts with neurotransmitters and brain pathways involved in mood, cognition, and stress response:

  • • Regulation of GABA & Serotonin – calming and mood-stabilising effects
  • • Increase in BDNF – supports neuroplasticity, memory, and learning
  • • Immune modulation – reduces inflammation and promotes immune balance
  • • Stabilisation of enkephalins – improves resilience to stress

Benefits of Selank

  • • Anxiety reduction without drowsiness or dependency
  • • Improved focus and mental clarity
  • • Mood stabilisation and emotional balance
  • • Enhanced memory and learning
  • • Stress adaptation and resilience
  • • Immune system support

Potential Applications

Selank is being studied and used in contexts such as:

  • • Managing anxiety and stress – non-sedating alternative
  • • Enhancing cognitive performance – for focus and clarity
  • • Emotional wellbeing – mood swings and low mood
  • • Immune health – as an adjunct therapy

Note: Selank remains investigational outside of research and clinical use. More studies are underway.

Administration

  • • Nasal spray – most common, non-invasive method
  • • Subcutaneous injection – used under supervision

Dosage and frequency vary by individual needs and are best determined under clinical guidance.

Safety and Side Effects

Selank is considered safe and well tolerated in clinical studies. Unlike benzodiazepines, it does not cause:

  • • Sedation
  • • Dependency
  • • Withdrawal symptoms

Mild side effects may include temporary nasal irritation (spray) or injection site reactions.
