What is Semax?
Increases BDNF — promoting new neural connections, protecting neurons, and enhancing learning.
Listed vial contents: 25mg. These are supplied quantities, not administration doses. Current pricing and availability are shown in the strength selector.
What mechanisms are being studied?
Semax is a synthetic heptapeptide derived from the ACTH(4-10) fragment, with a Pro-Gly-Pro C-terminal extension for metabolic stability. It increases brain-derived neurotrophic factor (BDNF) expression 1.5-3x, promoting neurogenesis, synaptic plasticity, and neuroprotection. It also modulates dopamine, serotonin, and acetylcholine neurotransmission. Administered intranasally for direct CNS delivery.
What are the research questions?
- Stroke recovery: Prescribed in Russia for over 25 years for acute ischemic stroke — reduced infarct volume by 25-40% when administered within 6 hours.
- Cognitive enhancement: Improves attention, memory formation, and learning capacity through BDNF upregulation.
- Optic nerve atrophy: Approved in Russia for treatment of optic nerve diseases — improved visual acuity and visual field.
- ADHD: Studied as an adjunct therapy for attention deficit disorders.
- Neuroprotection: Protective against oxidative stress, excitotoxicity, and traumatic brain injury.
What does the published work describe?
Dolotov OV et al. (Neuroscience 2006) — 1.5-3x BDNF increase confirmed. Prescribed in Russia/CIS since ~1995 for stroke, cognitive impairment, and optic nerve atrophy. Eremin KO et al. — Reduced infarct size 25-40% in stroke models.
What are the limits of this evidence?
The research described concerns the cited experimental materials and models, not proof that this supplied vial is a treatment. Cell or animal findings do not establish human benefits. Clinical findings, where cited, apply to the tested formulation and population; they do not validate this research product for human use.

How should I check lot documentation?
Match the product, strength and lot to an original analysis document. Literature describes experimental findings; it does not verify the contents of this inventory. A report is evidence only for the product, strength and lot it names.
How is Semax handled in the lab?
For Semax, record the product code SEMAX, selected strength and lot before opening. Follow the material-specific safety data sheet and laboratory SOP, with appropriate gloves, eye protection and containment. For a documented dry preparation, let the sealed vial equilibrate before opening to reduce condensation; minimize time open and use clean, compatible vessels.
Choose a solvent for Semax from the documented sequence or chemical identity, salt form and assay requirements. Test a small portion first and record pH, solvent composition and clarity. Do not assume one diluent works for every research material; include a solvent-only control and establish compatibility before using the stock in an assay.
For Semax, calculate mass concentration as measured material mass divided by final solution volume. Calculate molarity only with a documented molecular weight for the supplied chemical form; the catalog lists 813.93 g/mol as a reference, not lot confirmation. Where available, use matched-lot net content rather than treating chromatographic purity as a mass correction. Record both stock concentration and subsequent dilution factors.
Use the documented storage conditions for the supplied Semax form and lot. For a documented lyophilized preparation, keep the vial sealed and protected from moisture; for solutions, validate temperature, light exposure and holding time in the assay. Use compatible single-use aliquots when appropriate to reduce repeated freeze-thaw. No universal temperature or 28-day solution shelf life is established by the catalog name.
A Semax laboratory protocol should record identity, product code SEMAX, strength, lot, applicable analysis results, solvent and pH, stock concentration, dilution sequence, vessel type, storage history and assay endpoints. Include vehicle and reference controls, independent replicates and predefined acceptance criteria. Separate handling validation from biological interpretation; these notes do not provide administration or dosing instructions.
Research Use Only. Not for human consumption, therapeutic, veterinary or any in-vivo use.

Quality & Verification
Semax has a catalog purity specification of ≥99%; this is not a measured result for every vial. Match the product, exact strength, batch and lot to its analysis record and read only the reported fields. HPLC peak-area purity, measured content and endotoxin are separate measurements. A blank field means no result is reported, not zero or passed. A purity percentage alone does not establish identity, sterility or suitability for human use.
Frequently Asked Questions
What is Semax?
Semax is listed for cognitive laboratory research. Catalog vial contents are 25mg; select the required strength before ordering. This material is supplied for Research Use Only, not as a medicine or a product for human or veterinary use.
What strengths of Semax are available?
The catalog lists 25mg. These labels describe vial contents, not administration doses. Select the required strength for current pricing and availability; match analysis records to that exact strength and lot.
How should I interpret Semax purity results?
Semax has a catalog purity specification of ≥99%; this is not a measured result for every vial. Match the product, exact strength, batch and lot to its analysis record and read only the reported fields. HPLC peak-area purity, measured content and endotoxin are separate measurements.

How do I calculate a Semax stock concentration?
For Semax, calculate mass concentration as measured material mass divided by final solution volume. Calculate molarity only with a documented molecular weight for the supplied chemical form; the catalog lists 813.93 g/mol as a reference, not lot confirmation. Where available, use matched-lot net content rather than treating chromatographic purity as a mass correction. Record both stock concentration and subsequent dilution factors.
How should Semax be stored after preparation?
Use the documented storage conditions for the supplied Semax form and lot. For a documented lyophilized preparation, keep the vial sealed and protected from moisture; for solutions, validate temperature, light exposure and holding time in the assay. Use compatible single-use aliquots when appropriate to reduce repeated freeze-thaw. No universal temperature or 28-day solution shelf life is established by the catalog name.
What should a Semax lab protocol document?
A Semax laboratory protocol should record identity, product code SEMAX, strength, lot, applicable analysis results, solvent and pH, stock concentration, dilution sequence, vessel type, storage history and assay endpoints. Include vehicle and reference controls, independent replicates and predefined acceptance criteria. Separate handling validation from biological interpretation; these notes do not provide administration or dosing instructions.
Does Fmoc or Boc synthesis explain this Semax product?
Fmoc and Boc are peptide protecting-group strategies, not proof of how this Semax lot was made. For sequence-defined peptides, synthesis review can examine deletion products, incomplete deprotection and modifications using the method and matching analytical evidence. A single chromatographic peak does not by itself establish sequence.
Is Semax for human use?
No. Semax is strictly Research Use Only. It is not intended for human or veterinary use, diagnosis or treatment. Laboratory handling guidance is not an administration protocol.
Research Use Only. This product is intended for licensed laboratory research and is not for human or veterinary use.
