Selank hits fast—under 15 minutes
Nasal Selank kicks in within 3 to 15 minutes. You feel calmer without the fog. That's why it's popular in stress and cognition studies. Vials usually come in 10 mg or 20 mg. Reconstitute depending on nasal or injection.
This lays out dosing for both routes, cycles, and storage to keep it potent. Numbers pulled from actual protocols. BDNF boost or memory work? You'll find it here.
Reconstitute for nasal spray
Take a 10 mg vial. Add 10 ml bacteriostatic water. Now it's 1 mg/ml, or 1000 mcg/ml.
Shake gently 2-3 minutes till dissolved. Pull 9 ml into a sterile nasal spray bottle.
Each spray is roughly 0.1 ml: 100 mcg.
That's 90 sprays at 100 mcg each. For 300 mcg, hit 3 sprays per nostril. Absorption's about 50%, so it nets out right. Prime with 2 test sprays first.
Want it stronger? Use 5 ml water instead. Doubles to 2000 mcg/ml, 200 mcg per spray. Then 1-2 sprays per nostril gets your 300 mcg effective. Plug your vial into the Selank calculator for exact math.
SubQ injection protocol
10 mg vial, 2 ml water. 500 mcg per 0.1 ml.
Daily from research:
- Morning: 300 mcg (0.06 ml)
- Afternoon: 300 mcg (0.06 ml)
- Evening optional: 150 mcg (0.03 ml) for sleep checks
0.5 ml insulin syringe. Pinch abdomen skin, 45-degree angle, slow push. Switch spots daily.
SubQ peaks slower—30-45 minutes—but lasts up to 6 hours. Keep total under 900 mcg daily. No tolerance that way.
See DSIP for sleep or Semax for focus stacks.
Nasal or injection—which to pick?
Nasal rules research. Olfactory route crosses blood-brain barrier quick. 200-400 mcg, 2-3 times a day.
| Method | Dose per Admin | Frequency | Onset | Duration | Best For |
|---|---|---|---|---|---|
| Nasal Spray | 300 mcg | 2-3x/day | 3-15 min | 4-6 hours | Acute anxiety, focus |
| SubQ Injection | 300 mcg | 2x/day | 15-45 min | 6-8 hours | Sustained cognitive support |
Nasal absorbs 40-60%. 100 mcg spray? 3 total (1.5 per nostril). Injection's nearly 100% but needles.
I lean nasal for ease. One protocol: 300 mcg at 8 AM, 2 PM, 6 PM for 12 days.
Cycles for cognition studies
Don't run forever. Cycle to keep it working.
Beginner (anxiety):
- Days 1-10: 300 mcg nasal, morning + afternoon
- 11-17 off
- Up to 3 rounds
Advanced stack:
- 1-14: Selank 300 mcg nasal 3x + Semax 400 mcg nasal 2x
- 15-21 off
- Test cognition for BDNF changes
8-12 mg total per 14-day cycle. Stacking GHK-Cu? Cut Selank to 200 mcg.
Week off every two. Some push 20 on/10 off for memory, but returns drop after 14.
Storage that works
Dry powder? Room temp under 25 C, good 2 years.
Reconstituted:
- Fridge 2-8 C: 4 weeks
- Freezer -20 C: 6 months (thaw once)
Room temp kills it—20% drop weekly. Nasal over 2 weeks? Add 0.9% benzyl alcohol. Freeze 1 ml aliquots.
Travel: Ziplock lyophilized with silica. Mix on arrival.
Stacking combos
Selank plays nice.
Selank + Semax:
- Selank 300 mcg nasal 3x
- Semax 300 mcg nasal 2x
- 10 on/7 off
- Anxiety down, memory up
Selank + Ipamorelin (sleep-cognition):
- Selank 200 mcg nasal evening
- Ipamorelin 200 mcg subQ bed (Ipamorelin calculator)
Skip sedatives. Good with PT-141 for social stress.
Under 1 mg total peptides daily.
Fix common problems
Nasal burn: Dilute to 500 mcg/ml. Swap nostrils. Saline rinse after.
No kick: Recheck math—scale if you can. Try 400 mcg, max 600 daily.
Headache: Down to 150 mcg 2x. Drink more.
Tolerance: 7 days off fixes it.
Advanced from studies
Microdose: 100 mcg nasal every 4 hours, to 500 daily. Steady calm.
Load: Days 1-3 at 500 mcg 3x, then 250 mcg 2x.
Pulse: 400 mcg 30 min pre-exam.
Russian clinical doses match.

Log:
- Anxiety 1-10 daily
- Digit span test before/after 15 min
- Reaction time app
Day 5: 20-30% stress drop. Use Selank calculator.
FAQs
Question: What is the standard selank dosing for nasal administration in cognitive research?
Answer: You typically dose 300 mcg of Selank nasally, 2 to 3 times per day. Use 1 to 2 sprays per nostril depending on your spray concentration.
Question: How do you reconstitute Selank for subcutaneous injection?
Answer: Add 2 ml of bacteriostatic water to a 10 mg vial of Selank. This gives you 500 mcg per 0.1 ml. Draw up 0.06 ml for a 300 mcg dose.
Question: What cycle length do researchers use for Selank protocols?
Answer: Run Selank for 10 to 14 days, followed by 7 to 10 days off. Repeat as needed for cognitive enhancement studies.
Question: How should you store reconstituted Selank?
Answer: Keep lyophilized Selank at room temperature. Once reconstituted, store in the fridge at 2 to 8 C and use within 4 weeks.
Question: Can you combine Selank with Semax in nootropic research?
Answer: Yes, researchers often stack Selank at 300 mcg nasal with Semax at 300 to 600 mcg nasal, both 2 times daily. Check our Semax calculator for precise dosing.
