Semax is a synthetic heptapeptide (Met-Glu-His-Phe-Pro-Gly-Pro) originally developed for cognitive and neuroprotective research. This peptide has been extensively studied for its potential effects on brain-derived neurotrophic factor (BDNF) expression, cognitive function enhancement, and neuroprotective mechanisms in various laboratory models. Research contexts include investigations into memory formation, learning enhancement, and stress response modulation. Semax has also been explored for its potential interactions with the melanocortin system and enkephalin degradation pathways. The peptide's small size and high stability make it particularly suitable for in vitro neurological research. AllMyPeptides supplies Semax as a lyophilised research peptide with every batch independently HPLC-tested by UK-based third-party laboratories to verify 99%+ purity. A comprehensive batch-matched Certificate of Analysis accompanies every order, documenting all quality control parameters for complete research documentation. Supplied strictly for in-vitro laboratory research use only, and not for human or veterinary consumption or any clinical, diagnostic, or therapeutic use.
