Semax
Original price was: $39.99.$34.99Current price is: $34.99.
Semax is a synthetic heptapeptide belonging to the class of melanocortin derivatives. Structurally, it is an analog of adrenocorticotropic hormone (ACTH 4-10), modified to increase stability and resistance to enzymatic degradation. This structural adaptation allows researchers to investigate its activity in controlled laboratory settings with greater consistency compared to native peptide fragments.
Semax has been studied for its interactions with the central nervous system and its potential role in modulating neurochemical pathways. Research has explored its impact on neurotransmitter regulation, neuronal plasticity, and gene expression associated with neurotrophic factors. In experimental models, Semax is often evaluated for its potential to influence cognitive function, stress response, and neuroprotection.
As a research peptide, Semax 5mg is supplied in lyophilized form, requiring proper reconstitution prior to use in laboratory experiments.

Description
Semax is a synthetic heptapeptide belonging to the class of melanocortin-derived research peptides. Structurally, it is an analog of the adrenocorticotropic hormone fragment ACTH 4-10, modified to improve molecular stability and increase resistance to enzymatic degradation. These structural adaptations allow Semax to remain more stable than many naturally occurring peptide fragments, making it a useful compound for controlled laboratory investigations involving neurochemical signaling, peptide activity, and central nervous system research.
In experimental settings, Semax has been studied for its potential interactions with the central nervous system and its influence on pathways associated with neurotransmitter regulation, neuronal communication, and adaptive stress responses. Research has examined its possible relationship with dopaminergic, serotonergic, and other neurochemical systems involved in cognition, attention, and behavioral regulation. Because of these areas of interest, Semax is frequently evaluated in models focused on learning, memory, cognitive performance, and neurobiological response to stress.
Another major area of Semax research involves neuronal plasticity and neurotrophic factor expression. Neurotrophic factors play an important role in supporting neuron survival, growth, repair, and communication. Studies have explored how Semax may influence gene expression related to these factors, making it a compound of interest in research involving neuroprotection, cellular adaptation, and nervous system resilience under experimental conditions.
Semax has also been investigated for its potential role in oxidative stress response, inflammation-related signaling, and broader mechanisms connected to brain function and cellular protection. These research areas make it valuable for studying how synthetic peptide analogs may affect neurological pathways, stress-associated biological responses, and peptide-mediated regulation within controlled laboratory models.
As a research peptide, Semax 5mg is commonly supplied in lyophilized form to help preserve stability during storage and handling. Prior to laboratory use, it requires proper reconstitution using appropriate sterile technique and controlled preparation methods. Due to its defined structure, enhanced stability, and broad relevance in neurochemical and neurobiological research, Semax remains an important reference peptide for studies focused on melanocortin derivatives, nervous system signaling, neurotrophic activity, cognitive research models, and experimental peptide pharmacology.
