Description
Semax is a synthetic heptapeptide with the chemical sequence Met-Glu-His-Phe-Pro-Gly-Pro. It is an analog of the ACTH (4-10) fragment and was developed by the Russian Academy of Sciences. It is approved as a pharmaceutical in Russia, primarily for neuroprotection and cognitive enhancement. In other regions, it is mainly used as a research peptide or compounding preparation. Semax exhibits significant nootropic and neuroprotective effects, crosses the blood-brain barrier, and rapidly influences brain function. It is often used in combination with Selank. This content is intended for research and reference purposes only and should not be construed as medical advice.
Effects
Cognitive enhancement: Improves attention, memory, learning capacity, and information processing speed, with particularly pronounced effects under conditions of mental fatigue or stress. Neuroprotection: Promotes BDNF (brain-derived neurotrophic factor) expression, enhances neuroplasticity, and supports recovery from stroke, brain injury, or neurodegenerative disease. Anti-stress and mood regulation: Improves emotional stability, reduces anxiety, and supports stress management and mild depression. Other effects: May improve attention deficits (ADD/ADHD-like symptoms), enhance cerebral blood circulation, and support immune modulation and antioxidant activity. Characteristics: Relatively rapid onset, no notable sedation, and no disruption of the normal hormonal axis.
Usage
Common routes of administration: nasal spray/drops (most common and convenient, acting directly on the brain); subcutaneous injection (SC). Reference dosing (for reference only; follow physician's instructions): Nasal spray: 100–300 μg per dose, 1–3 times daily. Injection: 200–600 μg per dose, adjusted according to the specific protocol. Course of treatment: generally 10–14 days for cognitive enhancement; neurorehabilitation may require several weeks. Usage tips: Tilt the head slightly backward and spray gently when using the nasal spray; injections require aseptic technique. May be used alone or in combination with other neuropeptides such as Selank.
Not suitable for
Contraindicated in pregnant or breastfeeding women and in individuals under 18 years of age. Use with caution in individuals with epilepsy, severe hypertension, or psychiatric disorders. May potentiate the effects of other central nervous system drugs; consult a physician before combining medications. It remains a research compound in most countries, and long-term safety data are limited. Monitoring of bodily responses during use is recommended, and overdose should be avoided.
Questions about Semax
What is the intended use of Semax?
Research reagents are intended solely for laboratory and in-vitro research. Suitability for a particular experiment must be assessed using the exact specification and available documentation. Accessories and consumables must be used according to their own specifications and documented intended use.
Can research reagents be used by or administered to people?
No. Research reagents are not for human use, diagnosis, treatment, prevention, clinical procedures or self-medication. A research-use label does not authorize use in people.
How can I verify the identity of Semax?
No CAS number is published on this page. Do not infer the material's identity from its name. Request identification details and documentation for the exact product from the supplier.
Is a certificate of analysis (COA) available for Semax?
No COA is currently published on this page in the selected language. Ask the supplier about documents for the exact batch before use; availability is not guaranteed. A COA does not establish safety for human use or medical approval.
Does a purity result or COA establish safety for human use?
No. A reported purity result describes the sample and test recorded in the document. It does not establish safety for human use, clinical suitability or medical approval. Review the method, batch identity and relevant specifications for your laboratory work.
How should Semax be stored and handled?
The storage information published for this product is: Before reconstitution (lyophilized powder): store frozen at -20°C for long-term storage; refrigeration at 2–8°C is also suitable for several months; protect from light and moisture. After reconstitution / nasal spray solution: store refrigerated (2–8°C) and typically use within 2–4 weeks. Avoid high temperatures, light, and repeated freeze-thaw cycles.. Confirm the batch-specific storage and handling instructions with the supplier before receipt and use.
Does an available shipping option mean the product can be imported?
No. A shipping quote at checkout is not import authorization. Before ordering, verify whether the exact product and quantity are admissible at the destination and what purchasing, import, documentation and use requirements apply.
What should I confirm before procurement?
Match the SKU, specification and batch or lot identifier to your research requirements. Request any required COA and safety documentation and confirm availability before ordering; documents are not guaranteed to be available. Also verify applicable requirements at the destination.
