N-Acetyl Semax

Field	N-Acetyl Semax × Last updated 2 months ago
Aliases	N-Acetyl Semax amidate, Acetylated Semax, Ac-Semax, Semax analog
Category	Cognitive & Nootropic
Formula	C₃₉H₅₃N₉O₁₁S
Molecular weight	855.97 Da
Half-life	~hours (acetylated; longer than Semax)
Mechanism (summary)	In research catalogs, this compound is usually called N-Acetyl Semax amidate — a modified version of Semax (an ACTH(4-10)-derived heptapeptide). PubChem identifies the modified molecule, but indexed clinical evidence for the modified form is limited. Most meaningful biological and clinical discussion still comes from the parent peptide Semax.
Dosing notes	There is no standardized human dosing for N-Acetyl Semax. Parent-Semax regimens reported in the literature are intranasal and indication-specific: 6,000 mcg/day for 10 days, or acute-stroke 12 mg/day or 18 mg/day.

Storage	No approved label exists with product-specific N-Acetyl Semax storage instructions. Default synthetic-peptide handling: frozen, dry, light-protected lyophilized storage; careful aliquoting after reconstitution.
