Product Overview

Semax is a synthetic ACTH(4-10) analog with a PGP stability extension. Upregulates BDNF and NGF expression without adrenal activity — a premier neuroprotective and nootropic peptide for cognitive research.

Research Applications

  • ACTH(4-10) analog — no adrenal-stimulating activity
  • PGP extension: enhanced protease resistance
  • Upregulates BDNF and NGF via CREB-dependent transcription
  • Modulates serotonergic and dopaminergic systems
  • Over 100 publications in cognitive and neuroprotection research

Key Features

  • ≥99% purity confirmed by RP-HPLC and ESI-MS
  • For laboratory research use only
