N-Acetyl Semax 50 mg

N-Acetyl Semax 50 mg is Hilma Biocare's synthetic nootropic peptide, supplied as a single lyophilised vial. It is studied for focus, memory and neuroprotection, and the N-acetyl modification improves its stability.

What Semax Is

Semax is a heptapeptide derived from adrenocorticotropic hormone, specifically the ACTH 4-10 fragment with an N-terminal extension. Unlike ACTH, it does not stimulate the adrenal glands; instead it acts on the central nervous system. The N-acetyl version is more stable and has a longer half-life than the parent peptide. The 50 mg vial is a high-strength presentation for extended research.

The History of Semax

Semax was developed in the 1980s at the Institute of Molecular Genetics in Moscow, where researchers were studying peptide regulators of the nervous system. It was introduced in Russia for cognitive and neurological applications and has been studied in stroke and optic-nerve research. Its N-acetylated form became the standard research presentation. Western interest grew in the 2000s as nootropic research expanded.

How It Works

Semax influences the expression of neurotrophic factors, including BDNF and NGF, and modulates the balance of neurotransmitters in the brain. It is thought to act on the limbic system and cortex, supporting attention and memory consolidation. The peptide is rapidly degraded in plasma, but the N-acetyl modification slows this. It crosses into the brain more readily than many peptides.

What the Research Shows

• Russian studies examined Semax in stroke, cognition and optic-nerve conditions.
• Research reports increased BDNF and NGF expression.
• Animal models show improved learning and memory.
• Human data is limited but includes small clinical trials.

Research Context

Semax research began in the Soviet Union, and much of the early literature is in Russian. Studies have examined its use in stroke rehabilitation, optic-nerve disease and cognitive decline, often with small sample sizes and short follow-up. The peptide's ability to raise BDNF and NGF is the most consistent finding, and it has been used as a tool to study neurotrophic signalling. Western interest has grown more recently, but large randomised trials are still lacking, which is a common limitation across nootropic peptide research.

Strength, Pack and Authentication

Each vial contains 50 mg of lyophilised N-acetyl Semax, sealed and packed in a printed carton stating the compound, strength and vial count. A scratch-off security code inside the box can be checked against Hilma Biocare's records. The powder is stable before reconstitution and intended for research use only.
