Selank Dosing Protocol: 10 mg Vial — Extended Anxiety & Cognitive Protocol

Selank 10 mg vial guide — 20-day supply at 500 µg/day, ideal for extended anxiety management cycles without frequent reconstitution.

Go to peptide profileCalculate your dose

Quickstart highlights

Selank's extended 10-week protocols utilize BDNF upregulation (30–40% increase in hippocampal BDNF after 14+ days) and progressive enkephalin half-life normalization for durable anxiolytic effects that extend beyond the injection period.

  • Concentration: 2 mg/mL (10 mg vial + 5 mL bacteriostatic water).
  • At 2 mg/mL: 500 µg = 25 units once daily — the standard dose from Russian clinical trials.
  • Reconstitute 2.5 mL at a time (5 mg) to stay within the 28-day use window and avoid waste.
  • One 10 mg vial total provides 20 doses at 500 µg — approximately 20 days at once-daily dosing.
  • Inject in the morning for cognitive clarity; split 250 + 250 µg for all-day anxiety coverage.

WeekDose (µg)UnitsFrequencyNotes

Reconstitution steps

  1. Draw 5 mL bacteriostatic water (two 2.5 mL draws); inject slowly down the vial wall.
  2. Swirl gently until dissolved; do not shake.
  3. Final concentration: 2 mg/mL. Label with date; refrigerate at 2–8 °C. Use within 28 days.
  4. At 500 µg/day, 28-day window = 28 doses possible; however, 5 mL volume provides 50 doses — reconstitute 2.5 mL portions to stay within the window.

Protocol overview & cycle notes

Provide an extended Selank anxiolytic and cognitive enhancement protocol from the 10 mg vial, achieving continuous therapeutic BDNF upregulation and enkephalin stabilization over 8–10 weeks.

Cycle length: 10 weeks on.

Off-cycle: 4 weeks off; reassess anxiety symptoms (GAD-7) before resuming.

Storage & handling

Lyophilized: store below 25 °C. Reconstituted at 2 mg/mL: refrigerate 2–8 °C; use within 28 days. Reconstitute in 2.5 mL portions (5 mg each) to use within the 28-day window without wasting medication.

Injection & tracking tips

  • Morning injection is preferred — Selank's nootropic effects support focus during daytime cognitive tasks.
  • Splitting the dose (250 µg morning + 250 µg afternoon) provides sustained anxiolytic coverage throughout the day.
  • The 10 mg vial is most economical for extended 4–8 week protocols; reconstitute 2.5 mL at a time to respect the 28-day window.

Tracking

Logging helps you and your provider spot patterns and adjust dose or timing.

  • Track GAD-7 score weekly throughout the protocol.
  • Log daily productivity and task completion rates as cognitive performance metrics.
  • Record sleep quality (0–10) nightly — Selank's GABA-A modulation often improves sleep architecture.

How this works & references

Selank's extended 10-week protocols utilize BDNF upregulation (30–40% increase in hippocampal BDNF after 14+ days) and progressive enkephalin half-life normalization for durable anxiolytic effects that extend beyond the injection period. The 10 mg vial at 2 mg/mL provides 50 total doses — sufficient for 50 days at once-daily dosing. Reconstituting in 2.5 mL increments manages the 28-day window effectively.

Frequently asked questions

Why reconstitute only half the 10 mg vial at a time?
At 500 µg/day, a full 10 mg (5 mL) reconstitution would provide 20 days of doses — but the 28-day use window means you should complete a vial within 28 days. Reconstituting 2.5 mL (5 mg) at a time gives 10 days of doses within the window, then reconstituting the second 2.5 mL for days 11–20 maintains potency.
Does Selank improve sleep quality?
Yes — GABA-A modulation and reduced cortisol reactivity from Selank typically improve sleep onset and reduce nocturnal anxiety. Most users report improved sleep quality within 1–2 weeks of daily use. DSIP (Delta Sleep-Inducing Peptide) is sometimes stacked with Selank for patients whose primary complaint is anxiety-driven insomnia.
Can Selank be used indefinitely?
Russian protocols typically use 10–14 day intensive courses repeated as needed, or 10-week continuous protocols with 4-week off periods. No dependency or tolerance has been documented in Russian clinical data. Long-term use beyond 3 months continuously is not well-studied in peer-reviewed literature.
Is Selank safe for patients with liver disease?
Selank is metabolized by serum peptidases (not hepatic P450 enzymes) — there is no documented hepatotoxicity in animal or human studies. However, no formal pharmacokinetic data exists for patients with severe liver impairment. Use with caution and consult your hepatologist if you have liver disease.
Can I use Selank during a competitive sport season?
Selank is not currently on the WADA prohibited substance list (2026 edition). Athletes may use Selank without anti-doping concerns under current rules, though WADA classifications can change; verify with your national anti-doping organization before use in competition contexts.
