Semax Protocol: Complete Cycling & Dosing Guide
Overview
Semax is a synthetic heptapeptide analog of ACTH 4-10 originally developed for cognitive enhancement and neuroprotection. It operates primarily through upregulation of brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF), supporting neuroplasticity, neuronal survival, and neurotransmitter modulation.
The compound is available via two primary administration routes: intranasal spray (most common for self-administration) and subcutaneous/intramuscular injection. Intranasal dosing ranges from 200–600 mcg once or twice daily, while injection protocols typically use 200–500 mcg once daily.
Important: This guide is educational content only and does not constitute medical advice. Semax remains a prescription pharmaceutical in Russia with limited regulatory approval in Western countries. Consult a qualified healthcare provider before use, particularly if you have pre-existing medical conditions, take prescription medications, or are pregnant or nursing.
Standard Protocol
Baseline Dosing Structure
The most widely adopted protocol for intranasal Semax is 300 mcg once daily in the morning, escalating to 300 mcg twice daily (morning and midday) after 7–10 days of assessment.
Initial Phase (Days 1–10)
- Dose: 300 mcg once daily, administered intranasally in the morning
- Timing: 30–60 minutes after waking, on an empty stomach or light meal
- Purpose: Establish tolerability and establish baseline neurological effects
Escalation Phase (Days 11–21)
- Dose: 300 mcg twice daily (morning and early afternoon)
- Timing: Morning dose 30–60 minutes post-waking; second dose 6–8 hours later
- Purpose: Achieve therapeutic steady-state; assess response at higher frequency
Maintenance Phase (Week 4 onward)
- Dose: 300–600 mcg daily, split into one or two doses depending on individual response
- Frequency: Once or twice daily based on subjective benefit and tolerance
- Duration: Cycles typically run 8–12 weeks continuously, followed by a 1–2 week washout
Injectable Alternative
For subcutaneous or intramuscular administration:
- Standard dose: 250 mcg once daily
- Frequency: Once daily, typically in the morning
- Duration: Same 8–12 week cycle with 1–2 week breaks
- Advantage: Bypass nasal tissue irritation; more consistent pharmacokinetics
- Disadvantage: Requires sterile injection technique; higher barrier to entry for self-administration
Goal-Specific Protocols
Protocol A: Cognitive Enhancement & Memory
Cycle Duration: 10 weeks on, 2 weeks off
Week 1–2: 300 mcg once daily (morning) Week 3–10: 300 mcg twice daily (morning + early afternoon, 6–8 hours apart) Week 11–12: Washout (no Semax)
Rationale: Cognitive effects emerge gradually over 2–3 weeks as BDNF and NGF upregulation accumulates. Twice-daily dosing sustains elevated neurotrophic factor levels throughout waking hours, optimizing memory consolidation and encoding.
Expected Timeline:
- Week 1–2: Subtle mental clarity; baseline effects
- Week 3–5: Noticeable improvement in recall speed and focus duration
- Week 6–10: Sustained cognitive performance; potential plateau
Protocol B: Neuroprotection & Stress Resilience
Cycle Duration: 12 weeks on, 2 weeks off
Week 1–3: 300 mcg once daily Week 4–12: 300 mcg twice daily
Rationale: Stress resilience develops through sustained reduction in inflammatory gene expression and stabilization of HPA axis function. Longer on-cycles allow deeper integration of neuroprotective mechanisms.
Key Adjustments:
- If anxiety increases at 300 mcg twice daily, reduce to 250 mcg × 2 daily or maintain 300 mcg once daily
- Monitor cortisol-influenced symptoms (sleep quality, resting heart rate)
Protocol C: Injury Recovery & Rehabilitation
Cycle Duration: 12 weeks on, 3 weeks off
Week 1–2: 300 mcg once daily Week 3–12: 300–400 mcg twice daily (consider higher end of range if severe injury context)
Stacking: Combine with creatine monohydrate (5g daily) and omega-3 supplementation (2–3g EPA/DHA daily) for synergistic neuroprotection and inflammatory modulation.
Rationale: Animal data supports functional recovery via oxidative stress reduction and inhibition of pyroptotic pathways. Extended cycles maximize neuronal repair mechanisms. Longer washout allows neural circuits to stabilize without exogenous peptide support.
How to Administer Step-by-Step
Intranasal Administration
Equipment Needed:
- Semax nasal spray bottle (pre-filled) or reconstituted solution in nasal dropper
- Tissue or saline rinse (optional, for clearance)
Procedure:
- Preparation: Clear nasal passages gently. If severely congested, use saline spray 10 minutes prior.
- Positioning: Sit upright or recline slightly with head tilted back 30–45 degrees.
- Administration: Insert spray nozzle or dropper into one nostril. Close the opposite nostril with a finger.
- Delivery: Depress spray button or dropper firmly and inhale gently through the nose while spraying.
- Retention: Keep head tilted back for 30 seconds to allow absorption across the nasal epithelium.
- Repeat (if second dose): Administer to the opposite nostril using the same technique.
- Post-Administration: Remain upright for 2–3 minutes. Some drainage to the throat is normal; do not flush immediately.
Nasal Irritation Mitigation:
- Alternate nostrils with each dose to minimize localized irritation
- If burning or swelling occurs, reduce dose to 200 mcg or switch administration to every other day temporarily
- Saline rinse 30 minutes post-dose can reduce residual irritation
Subcutaneous/Intramuscular Injection
Equipment Needed:
- Sterile syringes (1 mL insulin or tuberculin syringes recommended for 200–500 mcg doses)
- Sterile needles (27–29 gauge for subcutaneous; 25 gauge for intramuscular)
- Alcohol prep pads
- Sterile vial of reconstituted Semax
- Sharps container
Reconstitution (if lyophilized powder):
- Use sterile bacteriostatic water or 0.9% saline at a ratio appropriate to target concentration
- For 10 mg powder: 10 mL sterile water = 1 mg/mL concentration
- Draw up dose (e.g., 0.25 mL for 250 mcg) into syringe
- Store reconstituted vial refrigerated (2–8°C); discard after 30 days
Injection Procedure:
- Site Selection: Subcutaneous: abdomen, upper arm, or thigh. Intramuscular: deltoid, vastus lateralis, or gluteus maximus.
- Cleaning: Wipe injection site with alcohol pad in circular motion; allow to dry.
- Needle Insertion: Subcutaneous: Insert at 45° angle; Intramuscular: Insert perpendicular (90°) to skin.
- Aspiration: Pull syringe plunger back slightly; if blood appears, relocate site.
- Injection: Slowly depress plunger over 2–3 seconds.
- Withdrawal: Remove needle; apply light pressure with clean gauze for 10–15 seconds.
- Rotation: Rotate injection sites to prevent lipodystrophy.
