🧠 Russian Anxiolytic Peptide

Selank Dosage Protocols: All Vial Sizes

Selank is a synthetic heptapeptide derived from tuftsin, developed by Russian researchers as an anxiolytic and nootropic without sedation or dependence.

Choose Your Vial Size

Vial	Final volume	Concentration	One U-100 unit
10 mg	2 mg/mL, 200 mcg at each verified 0.10 mL actuation, and 50 nominal actuations	—	—	Open protocol →
30 mg	—	—	100 mcg	Open protocol →

Doses are the same research amounts across sizes; the vial size changes the concentration, so syringe units differ. Always use the table for your exact vial.

Storage Instructions

State	Temperature	Duration
Lyophilized	−20°C (−4°F)	Up to 24 months, dry & dark
Reconstituted	2–8°C (35–46°F)	Up to 30 days, protect from light

Important Notes

⚠ Research Use Only: Selank is approved in Russia for anxiety disorders. Use elsewhere is research-grade.

How This Works

Selank is a synthetic heptapeptide (Thr-Lys-Pro-Arg-Pro-Gly-Pro) modeled on the natural immunomodulatory peptide tuftsin. It modulates GABA, serotonin, and BDNF (brain-derived neurotrophic factor) systems, producing anxiolytic effects without sedation, dependence, or cognitive impairment.

Potential Benefits & Side Effects

Potential Benefits

Anxiolytic effects without sedation or dependence.
Nootropic / mild cognitive enhancement reported.
Improved stress tolerance in animal models.
Long Russian clinical literature in anxiety disorders.

Side Effect Profile

Generally well-tolerated.
Mild injection-site or nasal-irritation possible.
Long-term human safety data outside Russian literature limited.

Lifestyle Factors

Intranasal route is most common in Russian clinical practice.
Cycled use (4-week on, 2-week off) is typical.

Injection Technique

Intranasal spray (most common) or subcutaneous.
Rotate injection sites if dosing sub-Q.
