What is Selank?
Selank is a synthetic heptapeptide developed in Russia as an anxiolytic (anti-anxiety) and nootropic agent. It’s a modified analog of the naturally occurring immunomodulatory peptide tuftsin, with an added Gly-Pro sequence for stability.
Selank is approved in Russia for anxiety and cognitive enhancement. Research shows effects on GABA, serotonin, dopamine, and BDNF — making it interesting for both mood and cognitive applications.
The 5mg vial provides approximately 10-20 days of research at typical doses.

Concentration Calculations
With 5mg in 2mL BAC water:
- Concentration: 2.5mg/mL = 2500mcg/mL
- Per unit (U-100): 25mcg per unit
Dosage Protocol
Common Dose Calculations
| Desired Dose | Draw Volume | Syringe Units |
|---|---|---|
| 250mcg | 0.10mL | 10 units |
| 400mcg | 0.16mL | 16 units |
| 500mcg | 0.20mL | 20 units |
Doses Per Vial
| Dose | Doses | Duration (2x/day) |
|---|---|---|
| 250mcg | 20 | 10 days |
| 500mcg | 10 | 5 days |
Suggested Protocols
Protocol A: Anxiolytic Focus
- Dose: 250-500mcg
- Frequency: 2-3x daily
- Duration: 2-4 weeks
Protocol B: Cognitive Enhancement
- Dose: 250mcg
- Frequency: 2x daily
- Duration: 2-4 weeks
Administration Routes
Selank can be administered:
- Subcutaneous — Standard injection
- Intranasal — Common in Russia (nasal spray formulation)
Storage Requirements
| Form | Temperature | Duration |
|---|---|---|
| Lyophilized | -20°C | 2+ years |
| Reconstituted | 2-8°C | 2-3 weeks |
Note: Selank is relatively fragile. Use within 2-3 weeks.
Research Considerations
Mechanism of Action
- GABA modulation — Anxiolytic effects
- Serotonin/dopamine — Mood regulation
- BDNF increase — Neuroplasticity
- Enkephalin inhibition — Extended action
- Immunomodulation — From tuftsin base
