Semax

Semax is a synthetic peptide derived from an ACTH fragment and studied for cognition, neuroprotection, stress response, and brain-repair models. It has been investigated in relation to memory, attention, ischemic brain injury models, neurotrophic factors, and gene-expression changes associated with neural plasticity. Researchers value Semax because it allows study of ACTH-derived peptide signaling without the full endocrine profile of ACTH itself. It is often categorized with cognitive and neuroregulatory peptides. Semax is especially relevant in models involving learning, stress resilience, brain inflammation, oxidative stress, and neurovascular recovery.
