Scientific Overview
Semax is a synthetic heptapeptide derived from an ACTH (4–10) fragment, engineered for enhanced stability and resistance to enzymatic degradation. It is widely studied in neurobiology research for its interactions with neurotrophic and neurotransmitter signaling pathways.
Selank is a synthetic peptide derived from the immunopeptide tuftsin, designed to improve molecular stability and reproducibility. In research literature, Selank is frequently evaluated for its influence on stress-related signaling and immune–neural pathway interactions.
When combined, Selank and Semax provide a complementary peptide pairing suitable for multi-pathway research involving neurochemical regulation, peptide transport, and intranasal formulation studies.
