Adamax

◎ Phase II (Russia/CIS countries)
N-Acetyl Semax Amidate (Adamax formulation)
Also known as: N-Acetyl Semax Amidate, Adamax nootropic, Semax amidate
Brand names: Adamax
Page last reviewed

Quick Summary

Adamax is a branded formulation of N-Acetyl Semax Amidate, the most potent and longest-acting analog of the nootropic peptide Semax. The N-acetyl modification at the N-terminus and amide modification at the C-terminus together extend its half-life and increase BDNF-stimulating potency compared to standard Semax.

Cognitive & Neurological Research Use
Adamax is a branded formulation of N-Acetyl Semax Amidate, the most potent and longest-acting analog of the nootropic peptide Semax. The N-acetyl modification at the N-terminus and amide modification at the C-terminus together extend its half-life and increase BDNF-stimulating potency compared to standard Semax. It is administered intranasally and is used in research for cognitive enhancement, neuroprotection, and focus.

Mechanism of Action

Adamax (N-Acetyl Semax Amidate) acts primarily through BDNF (Brain-Derived Neurotrophic Factor) upregulation, alpha-msh/" class="wiki-internal-link">melanocortin receptor modulation, and cholinergic system support.

BDNF Upregulation

N-Acetyl Semax Amidate has been shown to dramatically increase BDNF expression in the prefrontal cortex and hippocampus, regions central to working memory and executive function. BDNF supports neuronal survival, synaptic plasticity, and long-term potentiation.

Melanocortin Receptors

As an acth/" class="wiki-internal-link">ACTH(4-7) analog, Adamax activates MC4R in the brain, influencing dopamine and serotonin turnover, which improves motivation, attention, and stress resilience.

Cholinergic Enhancement

Research suggests Semax analogs enhance acetylcholine synthesis and release in the hippocampus, improving short-term memory encoding.

Research Summary

Russian Clinical Data

Semax (the parent compound) has been approved and used clinically in Russia since 1997 for ischemic stroke, optic nerve disease, and cognitive disorders. N-Acetyl Semax Amidate is the research evolution of this compound with enhanced potency.

Cognitive Performance

Human and animal studies on Semax analogs show improvements in attention span, working memory, and learning rate. N-Acetyl modification approximately doubles potency relative to standard Semax.

Neuroprotection

Animal stroke models show reduced infarct size and faster neurological recovery with Semax treatment, attributed to anti-inflammatory effects and BDNF-mediated neurogenesis.

Research Protocols

Dosing

Typical research dose is 100–300 µg intranasally. Some protocols go up to 600 µg but higher doses show diminishing returns on cognition.

Administration

Administer as nasal drops (not spray), tilt head back, apply drops, then tilt head forward to allow absorption through nasal mucosa. Each nostril absorbs independently.

Cycle

2–4 week cycles are common in research protocols. Some researchers use daily for 2 weeks then take 2 weeks off. Effects on BDNF may persist beyond the dosing period.

Storage & Handling

Adamax is supplied as a lyophilized" class="wiki-gloss-link">lyophilized powder. Reconstitute with sterile water or bacteriostatic water. Store reconstituted solution at 2–8°C and use within 30 days. Keep lyophilized powder frozen for long-term storage. Protect from light.
