2. What is Semax?

Semax is a synthetic peptide drug developed in Russia. Key points:

  • Composed of the ACTH(4-7) fragment (Met-Glu-His-Phe) with an added Pro-Gly-Pro at the C-terminus

  • Also known as MEHFPGP, I5FAL2585H, Pro-Gly-Pro-ACTH(4-7), ACTH(4–7)PGP

  • Molecular formula: C39H55N11O11

  • Developed by the Institute of Molecular Genetics of the Russian Academy of Sciences

  • Approved for medical use in Russia for various neurological conditions

3. Semax Mechanism of Action

Semax works through several mechanisms:

  1. Stimulates neurotrophic factors, particularly Brain-Derived Neurotrophic Factor (BDNF) and Nerve Growth Factor (NGF)

  2. Impacts serotonin, dopamine, and enkephalin signaling

  3. Modulates the expression of genes related to the immune system and vascular function

  4. May act as an antagonist or partial agonist of melanocortin receptors (MC4 and MC5)

  5. Inhibits enzymes involved in the degradation of enkephalins

4. Research Applications and Potential Benefits of Semax

Semax and Cognitive Performance

  • Improves attention and short-term memory

  • Enhances learning and mental clarity

Semax and Neuroprotection

  • Protects against pressure-induced nerve damage in glaucoma

  • Shows protective effects against various neurotoxins

  • Potential benefits in stroke and ischemic conditions

Semax and Mood Regulation

  • May have antidepressant-like and anxiolytic-like effects

  • Enhances stress resilience

Semax and Immune System Modulation

  • Affects the expression of cytokine genes

  • May have antiviral properties

5. Semax Dosage Guide

Dosing Semax for General Use

  • Typical dose: 300-600 mcg per day

  • Often divided into 1-3 doses

Dosing Semax for Cognitive Enhancement

  • Higher dose: 600-1200 mcg per day

  • Usually divided into 1-2 doses

Dosing Semax for Neuroprotection

  • Highest dose: 1000-3000 mcg per day

  • Often administered 1-2 times daily

6. How to Mix and Administer Semax

Semax is typically available as a pre-mixed nasal spray or solution. For research purposes:

  1. If using lyophilized powder, reconstitute with bacteriostatic water

  2. Use sterile equipment for mixing and administration

  3. Calculate dosage based on concentration (e.g., 0.1% or 1% solution)

7. Semax Administration Methods

Semax is primarily administered via intranasal route:

  • Tilt head back slightly

  • Insert dropper or spray nozzle into nostril

  • Administer prescribed dose

  • Allow solution to absorb through nasal mucosa

For research purposes, subcutaneous injection may also be used.

8. Semax Combinations and Interactions

Limited data on combinations. Potential synergistic effects with:

  • Nootropics (e.g., racetams)

  • Other peptides (e.g., Selank)

Always research potential interactions before combining substances.

9. Where to Buy Semax Online | 2024 Edition

Semax is available through specialized pharmacies in Russia. For research purposes, it may be obtained from reputable peptide suppliers. Always ensure third-party testing and proper documentation.

10. Is Semax Safe?

Generally considered to have a favorable safety profile:

  • No notable side effects reported in clinical trials

  • Safely administered in doses up to 12mg/daily for 10 consecutive days

  • Long-term safety data is limited

Potential side effects may include:

  • Headache

  • Nasal irritation

  • Slight anxiety at higher doses

11. Is Semax Legal?

  • Approved for medical use in Russia

  • Not approved by FDA or EMA for human use

  • Legal status varies by country

  • Often available as a research chemical, not for human consumption

12. Semax Storage and Handling

  • Store in a cool, dry place away from direct light

  • Refrigerate after opening

  • Use within 30 days after opening

  • Do not freeze

  • Keep out of reach of children

13. Frequently Asked Questions (FAQ)

How long does it take to see effects from Semax?

Effects may be noticeable within 5-30 minutes of administration, with peak effects occurring within 2-4 hours.

Can Semax be used long-term?

While some studies have used Semax for up to 30 days, long-term safety data is limited. Consult a healthcare professional for extended use.

Does Semax have any cognitive-enhancing effects in healthy individuals?

Some studies suggest improvements in attention and memory, but more research is needed to confirm these effects in healthy populations.

14. Semax Dosage | Final Verdict

Semax shows promise as a neuroprotective and cognitive-enhancing peptide with a favorable safety profile. The typical dosage range of 300-3000 mcg per day, depending on the application, appears effective for most research purposes. However, its use should be approached cautiously due to limited long-term safety data and varying legal status worldwide. As with any experimental compound, thorough research and professional consultation are essential before use.
