Semax is a synthetic heptapeptide (Met-Glu-His-Phe-Pro-Gly-Pro) derived from the ACTH(4–10) fragment, enhanced with a Pro-Gly-Pro stabilizing motif. It is commonly used in research examining central nervous system signaling, particularly through modulation of BDNF, TrkB receptors, and neurotrophin-regulated transcription factors such as NGF and GAP-43.
Semax has demonstrated neurotrophic, antioxidant, and monoaminergic effects in preclinical models, making it a popular peptide in experimental neuroscience for studies involving neuroplasticity, memory, stress response, and oxidative regulation. This formulation contains 11mg of lyophilized peptide, ideal for precision dilution and laboratory assay designs.

5 reviews for Semax
- 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.
Q: What is Semax commonly used for in research?
A: Semax is primarily used in neuroscience to study neuroplasticity, cognitive enhancement, neurotrophin signaling (e.g., BDNF), and transcriptional gene responses under stress or learning conditions.
Q: Does Semax influence mood or dopamine regulation?
A: Yes, research indicates Semax modulates monoaminergic signaling, especially dopamine and serotonin pathways, relevant to mood and behavioral regulation.
Q: How is Semax administered in studies?
A: It is commonly used in rodent studies via intranasal or subcutaneous routes. This 11mg vial is supplied in lyophilized form for precise reconstitution under laboratory protocols.
Q: Can Semax be used in human treatments or therapy?
A: No. This product is for preclinical laboratory research only. It is not approved for human consumption or therapeutic use.
Q: What makes Semax different from other ACTH analogs?
A: Its unique C-terminal PGP addition improves stability and CNS penetration while preserving neurotrophic effects, making it highly relevant for neurogenic and memory-related assays.
