What is Selank?
Selank is a synthetic heptapeptide ($Thr-Lys-Pro-Arg-Pro-Gly-Pro$) derived from the naturally occurring immunomodulatory peptide tuftsin. It is modified by adding three amino acids to its C-terminus to enhance metabolic stability and prolong its cellular half-life.
While structurally tied to the immune system, Selank exhibits pronounced anxiolytic (anxiety-reducing) and nootropic properties. It acts as a stable neuromodulator, influencing the expression of monoamine neurotransmitters (dopamine and serotonin) and altering the metabolism of leu-enkephalin via the inhibition of enkephalin-degrading enzymes.
Unlike conventional benzodiazepine anxiolytics, Selank manages anxiety-related pathways without inducing sedation, muscle relaxation, or cognitive impairment. Primary human research evaluates its efficacy via the intranasal route for conditions like generalized anxiety disorder (GAD), neurasthenia, and functional brain connectivity modulation. Selank is distributed strictly as a reference material for in-vitro laboratory testing and neurochemical research.
Potential Areas of Research
- Anxiolytic Neuromodulation: Investigated for its capacity to reduce clinical anxiety markers without sedating or impairing executive cognitive functions.
- Neurotransmitter Regulation: Studied for its downstream impact on dopamine, serotonin, and norepinephrine synthesis in the hippocampus and cortex.
- Enkephalin Preservation: Profiled for its enzyme-inhibiting action, which prevents the rapid breakdown of endogenous enkephalins to support natural stress management.
- Brain Connectivity Mapping: Examined via neuroimaging models to analyze immediate adjustments in functional connectivity and pharmaco-EEG patterns.

Preparation & Transfer Guide
Initial Vial Reconstitution:Requires Aseptic Setup.Wipe the rubber septum of the 10 mg lyophilized Selank vial with an alcohol pad. Using a sterile syringe, draw up exactly 3.0 mL of your sterile nasal vehicle. Slowly inject it down the inner glass wall of the vial. Gently swirl (do not shake) until the powder completely dissolves into a clear liquid.
Primary Actuator Transfer:Move Solution to Spray Bottle.Remove the metered pump mechanism from a clean, sterile 5 mL or 10 mL nasal actuator bottle. Using a fresh syringe or calibrated transfer pipette, extract the entire 3.0 mL mixture from the peptide vial and transfer it cleanly into the nasal spray bottle.
Volumetric Topping:Calibrate to Final Concentration.Add the remaining vehicle needed to reach your exact measured target volume. For the 5.0 mL option, add roughly 2.0 mL of vehicle. For the 10.0 mL option, add roughly 7.0 mL. Do not rely blindly on the bottle’s glass marking; use a calibrated syringe to ensure the total liquid volume is precisely 5.0 mL or 10.0 mL.
Seal and Prime:Ready for Device Validation.Secure the metered actuator pump tightly onto the bottle. Label the container clearly with the preparation date, exact concentration, and peptide identity. Before initiating research collection, prime the pump according to its technical instructions until a fine, uniform mist is established, noting the priming sprays in your log.
Actuator Mathematical Conversions
To map your custom preparation against published human literature amounts, apply these mathematical actuator conversions. Note that fractional sprays are theoretical calculations only, as a metered device can only express a complete 0.10 mL stroke.
- 300 mcg Research Target: Requires 1.5 theoretical sprays using the 5 mL volume setup, or exactly 3 complete sprays using the 10 mL volume setup.
- 900 mcg Research Target: Requires 4.5 theoretical sprays using the 5 mL volume setup, or exactly 9 complete sprays using the 10 mL volume setup.
- 2,700 mcg Research Target: Requires 13.5 theoretical sprays using the 5 mL volume setup, or exactly 27 complete sprays using the 10 mL volume setup.
Storage
- Lyophilized Powder (Before Mix): Store at 2–8°C (36–46°F) under dark, moisture-free conditions. For long-term preservation spanning several months, keep stored at −20°C (−4°F).
- Reconstituted Custom Solution (After Mix): Store continuously refrigerated at 2–8°C (36–46°F) and protect from light exposure. If using an unpreserved saline vehicle, utilize the solution within 10 to 14 days to maintain sterility.
- Note on Registered Equivalents: Commercial, pre-formulated 0.15% Selank drop solutions containing stabilizers permit a temporary 15-day storage window up to 25°C (77°F), but unpreserved custom research batches should always remain strictly refrigerated. Never expose the peptide to freezing temperatures once mixed.
Research Controls & Technical Notes
- Pump Variability: Actuator outputs are not universally identical. Standard commercial pumps can vary anywhere from 0.025 mL to 0.20 mL per stroke. Verify your specific hardware specifications prior to calculating final metrics.
- Delivery Performance Variables: In alignment with standard regulatory guidance for nasal spray delivery systems, factors such as bottle orientation (always hold upright), stroke force, priming consistency, and residual tail-off volume near bottle exhaustion must be tracked and logged as active experimental variables.
- Observed Effects & Tolerance: In human trials, transient adverse effects are rare but can include brief altered or unpleasant taste sensations and localized nasal membrane sensitivity. Selank does not display signs of habituation, cognitive slowing, or typical withdrawal symptoms in clinical literature.
