VIAL

Freeze-dried powder in a sealed glass vial. Reconstitute with bacteriostatic water and administer via syringe. The most versatile and cost-effective research format.

RECONSTITUTION & SYRINGE REQUIRED

CARTRIDGE

Pre-filled and ready to administer. Slides into a reusable pen injector — no measuring or mixing required. Clean, discreet, and consistent across research protocols.

REQUIRES COMPATIBLE PEN INJECTOR

NASAL

Delivered via mucosal absorption — no needles required. A popular choice for research protocols where needle-free administration is preferred.

NEEDLE-FREE — SPRAY & GO

PEN

An all-in-one auto-injector with the cartridge pre-loaded. Dial, click, and administer. Optimal for high-frequency research protocols requiring precise, repeatable dosing.

DIAL, CLICK & INJECT — NO PREP

Vials are freeze-dried (lyophilised) powder — kept refrigerated unopened, they remain stable for up to 2 years.

Cartridges, nasal sprays, and pens arrive pre-filled as liquid, must be kept refrigerated at all times, and carry a Beyond Use Date — typically 4–8 weeks from receipt. Please refer to the BUD on the label.

N-Acetyl Semax Amidate (also known as N-Acetyl Semax NH₂ or Ac-Semax Amidate) is a synthetic heptapeptide derived from Semax with two key stabilizing modifications: N-terminal acetylation and C-terminal amidation. These changes significantly improve enzymatic resistance (especially against aminopeptidases), enhance metabolic stability, and often improve blood-brain barrier penetration and duration of action compared to standard Semax.

This research compound retains the core ACTH(4-10) analog sequence (Met-Glu-His-Phe-Pro-Gly-Pro) and is studied for its potent nootropic, neuroprotective, neurotrophic, and cognitive-enhancing properties. Preclinical research suggests it strongly upregulates BDNF and TrkB expression, modulates dopaminergic and serotonergic systems, reduces oxidative stress and neuroinflammation, and supports neuroplasticity with potentially superior pharmacokinetics to unmodified Semax.

Sequence

Ac-Met-Glu-His-Phe-Pro-Gly-Pro-NH₂ (N-terminal acetylation, C-terminal amidation)

Research Applications

Cognitive Enhancement & Nootropic Effects
Studied for improvements in memory, learning, attention, and mental performance under stress, fatigue, or aging conditions.
Neuroprotection
Investigated in models of cerebral ischemia, stroke recovery, traumatic brain injury, and neurodegeneration for its ability to reduce neuronal damage, apoptosis, and oxidative stress.
BDNF & Neurotrophic Support
Promotes BDNF expression and hippocampal neurogenesis, supporting long-term synaptic plasticity and cognitive resilience.
Anti-Inflammatory & Anti-Stress Action
Modulates neuroinflammation and helps normalize neurotransmitter balance during acute or chronic stress.
Peptide Optimization
The dual modification (N-acetylation + C-amidation) is commonly researched for better stability, longer half-life, and enhanced intranasal or systemic efficacy compared to native Semax.

Storage & Handling

Lyophilised vials are stable at −20°C for up to 2 years unopened. Once reconstituted, refrigerate at 2–8°C and use within 28 days. Avoid repeated freeze-thaw cycles.

Beyond Use Date

Pre-filled formats (cartridge, pen, nasal) carry a beyond-use date of typically 4–8 weeks from receipt. ≥98% purity by HPLC. For in vitro and preclinical research use only — not for human or veterinary use.
