What this is
This guide covers intranasal use of Semax and Selank, based on Russian clinical research patterns, common experimental protocols, and real-world nasal spray delivery constraints.
There are no FDA-approved dosing standards. Everything here should be viewed as informed guidance — not medical prescription.
Your base solution
If you mixed 10mg Semax + 10mg Selank in 10mL bacteriostatic water, your concentration is:
Semax1 mg/mL
Selank1 mg/mL
~0.1 mL per spray~100 mcg Semax + 100 mcg Selank per spray
Effective dose range
Semax300 – 900 mcg/daySplit into 1–3 doses/day · Clinical use: 10–14 day courses
Selank300 – 800 mcg/daySplit into 2–3 doses/day · Stress, cognitive modulation
Translation to your spray: 1 spray = 100 mcg each. 3–6 sprays/day sits inside the range used in the research.
Simple daily protocol
Morning1 spray per nostril2 total
Midday / afternoon1–2 additional sprays
Total3–4 sprays/day
This lands you at ~300–400 mcg Semax + ~300–400 mcg Selank — squarely inside the most consistently used research range.
Cycling strategy
Evidence-aligned10–14 days onThen 2–4 weeks off
Performance-oriented5 days on / 2 days offRun for 3–4 weeks, then take 2+ weeks off completely
What to avoid
- Continuous daily use for months (no real data)
- Blind "4 on / 3 off forever" cycles
- Escalating dose to chase effects
If you need to increase dose to feel anything, that's already a signal to stop.
Bottle longevity
Capacity10 mL ≈ 100 sprays
At 3–4 sprays/day~25–33 days per bottle
This is the sweet spot: steady dose, clean monthly usage, no overuse.
What effects should actually feel like
Semax- Increased mental clarity
- Better task switching
- Subtle stimulation (not jittery)
Selank- Less background tension
- Smoother emotional baseline
- Less stress reactivity
Red flags
Stop or reassess if you notice:
- Diminishing effects within days
- Needing higher doses quickly
- Emotional flattening or apathy
- Headaches or irritability
These compounds aren't meant to be "felt" strongly — they're meant to quietly improve function.
Bottom line
The most defensible, research-aligned setup:
Dose3–4 sprays/day
Amount~300–400 mcg each peptide daily
Cycle10–14 days ON
BreakFull break between runs
Real effectMinimal tolerance riskSustainable long-term use
