Description
Semax
Semax – 5mg or 11mg (Lyophilized Peptide) – For Research Use Only
Semax is a synthetic peptide derivative of adrenocorticotropic hormone (ACTH 4-10) that has been extensively studied for its potential neuroprotective and cognitive-enhancing effects. Originally developed in Russia, Semax is believed to modulate brain-derived neurotrophic factor (BDNF) and influence neurotransmitter systems.

Semax Nasal Spray peptide Details
Semax Nasal Spray — Research Grade | Pre-Formulated Liquid Solution
This nasal spray formulation delivers Semax as a pre-formulated, sterile liquid solution for research use. No reconstitution is required — the product arrives ready for laboratory application via the nasal spray delivery format.
Semax is a synthetic heptapeptide (Met-Glu-His-Phe-Pro-Gly-Pro) developed in Russia by the Institute of Molecular Genetics. It is an analogue of the ACTH(4-10) fragment and has been studied for its neuroprotective, nootropic, and BDNF-stimulating properties in preclinical models. Research has explored its potential role in cognitive function, neuroregeneration, and ischemia models.
Nasal spray format note: This product is supplied as a metered-dose nasal spray bottle. Intranasal Semax delivery is the primary format investigated in the research literature and has established precedent in Russian research and clinical contexts for its CNS-targeted delivery profile. All use is strictly for laboratory and research purposes only.
⚠️ For Research Use Only — Not for human consumption. Requires 2nd Day Air or Next Day Air shipping (no ground shipping available).
Semax Nasal Spray peptide Scientific Research
- Neurotrophin-Driven Gene Expression
Semax promotes expression of neurotrophic markers such as BDNF and NGF. Studies focus on hippocampal and cortical regions where BDNF/TrkB activity influences plasticity and cognitive function. - Cognitive and Memory Paradigms in Rodents
Used in learning and memory tasks (e.g., Morris water maze, T-maze), Semax has been evaluated for enhancing cognitive performance in aging or stress-exposed models. - CNS Systems-Level Imaging Studies
Functional and resting-state imaging has shown Semax's influence on connectivity and region-specific network activation in rodent brain studies. - Monoaminergic and Dopaminergic Modulation
Preclinical trials link Semax to regulation of serotonin and dopamine systems, with relevance to reward, motivation, and mood-linked behaviors. - Antioxidant and Cytoprotective Pathways
Semax has been studied for reducing lipid peroxidation and enhancing antioxidant enzyme expression in oxidative-stress models, particularly in brain and liver tissues. - Inflammation and Immune-Gene Modulation
Gene expression profiling in rodent studies indicates that Semax influences transcriptional activity in neuroimmune and neurovascular regulatory pathways.

Handled correctly, stability holds
All peptides are supplied as sterile, lyophilized powder and are stable when handled correctly.
Store vials in a cool, dry place away from heat and direct sunlight.
For optimal longevity, keep lyophilized peptides refrigerated to help maintain integrity.
Use an appropriate research diluent (for example, BAC water). Store the reconstituted solution in the refrigerator and use within 20–30 days for best stability.
Minimize exposure to moisture and repeated freeze–thaw cycles. Follow your institution's safety procedures when handling research materials.
Frequently Asked Questions
PRODUCT & PURITY
This product is offered for laboratory and research use only. It is not intended for human consumption, medical use, therapeutic use, or veterinary use.
Yes, all of our products are sterile and sealed with a sterility plug and safety cap.
Our products undergo quality control internally at our lab and then 3rd party tested at Bioviridian (at their Texas facility) prior to shipment. All of our COA's are then posted on our site immediately upon receipt.
99% or higher. Period. The expected purity is listed on the individual product page or Certificate of Analysis, when available.
No. We are a manufacturing company and because these products are sold for research purposes only, we do not provide dosing, administration, or medical-use guidance.
Unless specifically stated otherwise, these products are not approved by the U.S. Food and Drug Administration for therapeutic or diagnostic use.
STORAGE & STABILITY
As a lyophilized powder, peptides are stable. Delays in shipments up to 7 days will have zero to minimal impact on efficacy of peptides. Most precautionary efforts must be made to maintain temperature consistency once reconstituted.
Store the product according to the storage recommendations provided on the label or accompanying documentation in your shipment. Proper storage helps maintain product integrity during its shelf life. Most peptides have an expiration date of 2 years if kept unreconstituted (lyophilized powder).
SHIPPING
Shipping times vary based on your location and the shipping method selected at checkout. We offer shipping options between 1 and 5 days.
No.
Once your order is processed, you will receive a shipping confirmation email with tracking information.
