What is Semax?
Semax is a synthetic heptapeptide analog of ACTH(4-10). It is commonly discussed in cognitive enhancement, attention, memory, neuroprotection and brain-health research.
The source protocol notes that most human clinical literature uses intranasal Semax, while this page converts the information into a subcutaneous reconstitution and measurement guide for educational reference.
Semax Reconstitution Example
The example below is based on a common 10mg Semax vial mixed with 3.0mL bacteriostatic water.
Reconstitution Maths
10mg ÷ 3.0mL = 3.33mg/mL
3.33mg/mL = 3,333mcg/mL
1 unit on a U-100 syringe = 0.01mL
3,333mcg/mL × 0.01mL = approximately 33.3mcg per unit
Semax Unit Conversion Table
Standard Gradual Research Example
This example uses a 10mg vial reconstituted with 3.0mL bacteriostatic water, giving a concentration of approximately 3.33mg/mL.
Frequency and Timing Notes
Semax is commonly discussed as a once-daily subcutaneous compound in the source protocol. The source also notes that most human nootropic studies use intranasal dosing in divided daily administrations.
Timing is usually flexible. The main practical point is consistency, tracking response and rotating injection sites. For smaller volumes around 9 units, 30-unit or 50-unit insulin syringes may be easier to read than a full 1mL syringe.
Reconstitution Steps
- Confirm the vial size before calculating concentration.
- Draw 3.0mL bacteriostatic water using sterile technique.
- Inject the bacteriostatic water slowly down the inside wall of the vial.
- Avoid blasting the powder directly and avoid creating foam.
- Gently swirl or roll the vial until dissolved.
- Do not shake vigorously.
- Label the vial with the reconstitution date and concentration.
- Store refrigerated at 2-8°C, protected from light.
Supplies Needed
Semax Vials
- 8-week example: approximately 4 × 10mg vials.
- 12-week example: approximately 6 × 10mg vials.
- 16-week example: approximately 8 × 10mg vials.
Insulin Syringes
- Daily example: 7 syringes per week.
- 8 weeks: approximately 56 syringes.
- 12 weeks: approximately 84 syringes.
- 16 weeks: approximately 112 syringes.
Bacteriostatic Water
- Per 10mg vial: 3.0mL bacteriostatic water.
- 8-week example: 4 vials × 3.0mL = 12mL total, so 2 × 10mL bottles may be needed.
- 12-week example: 6 vials × 3.0mL = 18mL total, so 2 × 10mL bottles may be needed.
- 16-week example: 8 vials × 3.0mL = 24mL total, so 3 × 10mL bottles may be needed.
Alcohol Swabs
- Per administration: one swab for the vial stopper and one for the injection site.
- Per week: approximately 14 swabs based on daily administration.
- 8 weeks: around 112 swabs, so 2 × 100-count boxes may be needed.
- 12 weeks: around 168 swabs, so 2 × 100-count boxes may be needed.
- 16 weeks: around 224 swabs, so 3 × 100-count boxes may be needed.

- Concentration: approximately 3.33mg/mL.
- Cycle length: 8 weeks continuous is commonly discussed.
- Optional extension: 12-16 weeks with rest periods, such as 6 weeks on and 2 weeks off.
- Storage: lyophilised frozen, reconstituted refrigerated and used within around 30 days.
Example Dosing Protocol
- Start: 300mcg daily.
- Titration: increase by around 100-200mcg every 1-2 weeks as tolerated.
- Target example: 600-800mcg daily by weeks 5-8.
- Frequency: once daily in the source protocol.
- Timing: any consistent time of day is commonly discussed.
How Semax Works
Semax is a synthetic analog of the ACTH(4-10) fragment with a Pro-Gly-Pro extension that is discussed as improving metabolic stability.
Clinical and preclinical literature cited in the source discusses Semax in relation to BDNF expression, cholinergic and dopaminergic neurotransmission, neuroprotection and cognitive impairment models.
Human studies referenced in the source material commonly involve intranasal administration in areas such as cognitive support, ischemic stroke, optic neuropathy and other neurological research contexts.
Potential Benefits Discussed in Research
- Attention and focus research
- Memory consolidation and learning discussions
- BDNF-related pathway research
- Cholinergic and dopaminergic neurotransmission discussions
- Neuroprotection research
- Stroke and neurological recovery research contexts
- Optic neuropathy research contexts
- Cognitive impairment research
Reported Side Effects and Limitations
- Mild injection-site redness
- Itching or local irritation
- Minor nasal irritation in intranasal studies
- Dose-dependent response
- Most human data discussed intranasal rather than subcutaneous Semax
- Unknown long-term outcomes outside studied settings
- Not a guaranteed focus, memory, stroke-recovery or neuroprotection treatment
Storage Instructions
- Lyophilised powder: store frozen at around -20°C in dry, dark conditions.
- After reconstitution: refrigerate at 2-8°C.
- Use window: commonly discussed as up to 30 days after reconstitution.
- Protect from light: wrap vials in foil or store in an opaque container.
- Avoid: heat, sunlight, moisture, contamination and repeated freeze-thaw cycles.
- Practical note: allow vials to reach room temperature before opening to reduce condensation uptake.
Injection Technique Notes
This section is general educational information only. It is not personal injection instruction.
- Use a new sterile insulin syringe for each administration.
- Clean the vial stopper and injection site with alcohol and allow both to dry completely.
- Common subcutaneous sites discussed include abdomen, thighs and upper arms.
- Rotate injection sites systematically, keeping at least 1-2 inches between injection sites.
- Pinch a 1-2 inch skinfold and insert into subcutaneous tissue at an appropriate angle.
- Do not aspirate for subcutaneous injections.
- Inject slowly and steadily.
- Withdraw the needle at the same angle and apply gentle pressure if needed.
- Do not rub the site vigorously.
- Dispose of used sharps safely in a sharps container.
Lifestyle Factors That May Matter
- Sleep: consistent sleep schedules and 7-9 hours of quality sleep may support cognitive function.
- Exercise: regular aerobic exercise may support neuroplasticity and brain health.
- Cognitive training: learning new skills and challenging tasks may support cognitive adaptation.
- Nutrition: omega-3 fatty acids, antioxidants and micronutrients are commonly discussed for brain health.
- Stress management: mindfulness, meditation and relaxation practices may support cognitive performance.
- Tracking: documenting amount, date, timing and injection site can make tolerance patterns easier to review.
