N-Acetyl Semax

Acetylated, more stable analog of Semax; longer-acting nootropic via BDNF/NGF upregulation.

Scientific Overview

N-Acetyl Semax is an N-terminal acetylated derivative of Semax (the ACTH(4-7) analog Pro-Gly-Pro fragment) developed at the Russian Institute of Molecular Genetics. Acetylation blocks aminopeptidase cleavage, extending half-life. Like Semax it raises BDNF/NGF and modulates dopaminergic tone. Schedule status varies; not FDA-approved.

Key Research Benefits

  • ✓Memory and focus
  • ✓BDNF/NGF upregulation
  • ✓Longer half-life vs Semax

Potential Side Effects

⚠Headache (rare)
⚠Insomnia if dosed late
