About Semax
Semax is a synthetic heptapeptide (Met-Glu-His-Phe-Pro-Gly-Pro) derived from the ACTH(4-10) fragment. Developed in Russia, it has been studied extensively for neuroprotective and cognitive endpoints, including upregulation of brain-derived neurotrophic factor (BDNF) and neuroplasticity research. An acetylated variant, N-Acetyl Semax, offers enhanced potency and longer action.
Semax is sold worldwide as a research-use-only (RUO) compound. It is often compared to Selank for nootropic research. Purity and formulation vary significantly between suppliers — third-party lab data is the key signal when comparing options.

Particle PeptidesSemax vs N-Acetyl Semax vs Selank
Three closely related nootropic peptides from the Russian research tradition — each with distinct properties:
- Origin — Semax and N-Acetyl Semax derive from the ACTH(4-10) fragment; Selank derives from tuftsin — a different peptide class entirely
- Effect profile — Semax is studied for stimulating, cognitive-enhancing effects with BDNF upregulation; Selank has more anxiolytic and calming properties; N-Acetyl Semax is generally considered more potent than base Semax
- Duration — N-Acetyl Semax has a longer effective duration than unmodified Semax due to enhanced membrane permeability; Selank has a comparable short half-life to base Semax
- Research pairing — Semax and Selank are sometimes studied together for complementary cognitive and anxiolytic endpoints
Frequently Asked Questions
What is Semax?
Semax is a synthetic heptapeptide (Met-Glu-His-Phe-Pro-Gly-Pro) derived from the ACTH(4-10) fragment. It is studied in research for neuroprotective and cognitive endpoints, including BDNF upregulation and neuroplasticity.
Where can I buy Semax?
Semax is sold by multiple research peptide suppliers worldwide. The suppliers above ship to the United States, EU, UK, and other regions, with available lab data and certificates of analysis.
What is the difference between Semax and N-Acetyl Semax?
N-Acetyl Semax is an acetylated analog of Semax with enhanced membrane permeability and a longer effective duration. Both are studied for similar cognitive and neuroprotective endpoints, but N-Acetyl Semax is generally considered more potent per unit dose.
How is Semax different from Selank?
Both are nootropic peptides with Russian research origins. Semax (ACTH-derived) tends to produce more stimulating, cognitive-enhancing effects with BDNF upregulation. Selank (tuftsin-derived) has more pronounced anxiolytic and calming properties. They are often studied together for complementary effects.
