N-Acetyl Semax is a synthetic peptide being studied for its potential neurogenic and neurorestorative properties. While it has gained approval for clinical use in Russia, its evaluation in other countries is still pending, the USA included. Extensive research has demonstrated its ability to enhance memory and cognitive function, making it a promising candidate for addressing various neurological conditions. Furthermore, N-Acetyl Semax research suggests the chemical compound’s possibility to combat diseases related to the optic nerve, stroke, and ischemic heart disease.

N-Acetyl Semax Product Details

N-Acetyl Semax is a synthetic semax peptide that serves as an analog of the hormone ACTH. While ACTH and its analogs primarily exert hormonal effects, they also exhibit non-hormonal benefits, such as enhancing learning and memory capabilities and maintaining muscle tone. The exact mechanism of action for N-Acetyl Semax is not yet fully understood, but it is believed that the peptide semax affects the interaction among melanocortin receptors present in the nervous system.

One of the key functions of Semax is its ability to stimulate the synthesis of brain-derived neurotrophic factor (BDNF), a peptide produced by neurons that is essential for various neural functions, including the proper functioning of the retina (leading to improved contrast and sharper vision under the influence of nootropic substances), cholinergic and dopaminergic neurons.

BDNF plays a vital role in the formation of new neural connections and prolongs the lifespan of existing cells. It is particularly involved in the formation of long-term memory and supports all brain activities associated with the generation of new neurons, including the acquisition of new motor skills or the enhancement of strength.

N Acetyl Semax is commonly confused with N Acetyl Semax Amidate. The latter is a variant of the former and is believed to offer a more potent effect.

Potential Benefits of N-Acetyl Semax

As a result, unless otherwise specified, the “potential uses” outlined below should be regarded as “insufficient evidence” until much more additional study — preferably in large samples of healthy human users — is conducted.

Furthermore, one key caution to be aware of is that the majority of early Semax studies were undertaken by Russian research teams and have not been translated from Russian. This implies that many of these research specifics cannot be accessed for critical review.

Ischemic Stroke

In a noteworthy clinical trial involving 110 test subjects, the use of Semax demonstrated promising results in facilitating early rehabilitation for participants with ischemic stroke, regardless of the stage of the condition. [R]

During the study, administration of Semax exhibited a notable impact on brain-derived neurotrophic factor (BDNF) plasma levels, which remained consistently elevated throughout the entire study duration. Importantly, in the subgroups of clinical subjects receiving Semax, higher BDNF plasma levels were found to be positively correlated with achieving early rehabilitation milestones. [R]

These findings suggest that Semax may hold potential as a valuable intervention for ischemic stroke test subjects, as it not only promotes increased BDNF plasma levels but also establishes a favorable association with early rehabilitation outcomes. Further research and investigations are warranted to fully explore and validate the clinical implications and broader applications of Semax in stroke rehabilitation. [R]

Pain Reduction

A compelling rat study indicates that Semax exhibits analgesic effects regardless of the method used to induce pain. The research encompassed various types of painful stimuli, including thermal (hot plate and tail flick tests), mechanical (hind leg squeezing), and chemical (writhing). Notably, Semax consistently demonstrated an increase in pain threshold across these different tests, indicating that its analgesic properties are not contingent upon the specific type of pain stimulus employed. [R]

These findings suggest that Semax possibly possesses a broad-spectrum analgesic effect, capable of alleviating pain induced by diverse irritants. By effectively raising the pain threshold, Semax showcases its potential as a possible candidate for pain management, warranting further investigation to elucidate its precise mechanisms of action and potential clinical applications. [R]

Eye Disorders

A notable study conducted in 1999 provides evidence supporting the potential therapeutic utility of Semax in the treatment of optic nerve diseases.

The study revealed that the addition of Semax to the therapeutic regimen for test subjects with optic nerve diseases yielded favorable outcomes in terms of the intensity and pace of recovery, as well as improvements in visual functions. Semax exhibited a protective effect on nervous tissue, particularly during the acute stage of optic nerve disease, demonstrating its ability to mitigate the aftereffects of injury. [R]

The administration of Semax resulted in positive changes in the clinical presentation, as evidenced by enhancements in visual acuity, expansion of the total visual field, increased electric sensitivity and conductivity of the optic nerve, and improvements in color vision. These findings strongly suggest that Semax can exert a beneficial influence on the visual system and may serve as a valuable component in the management of optic nerve diseases. [R]

Further research and investigations are warranted to build upon these findings, allowing for a deeper understanding of Semax’s mechanisms of action and its potential implications for optimizing visual function and therapeutic interventions in optic nerve diseases. [R]

Traumatic Brain Injury

Semax emerges as a promising alternative for the treatment of traumatic brain injury, as supported by findings from a cell culture study.

Extensive research has demonstrated that certain regions of the brain harbor neural progenitor/stem cells (NPSCs), which play a crucial role in the generation of new neurons and glial cells. [R]

A specific investigation unveiled that Semax, a potential candidate for traumatic brain injury therapy, exerts a direct and positive influence on the proliferation of endogenous NPSCs within the sub-granular zone (SGZ) of the hippocampal dentate gyrus (DG). This effect is mediated through the BDNF/TrkB pathway system, a significant signaling mechanism involved in neurogenesis.[R]

By enhancing the proliferation of NPSCs, Semax opens up new possibilities for developing therapeutic strategies during the acute phase of traumatic brain injury. Harnessing the innate neurogenic capacity of the brain becomes a viable approach for repopulating and repairing damaged brain tissue. These advancements hold promise for restoring brain function and facilitating the recovery process following traumatic brain injury. [R]

Further investigations are essential to comprehensively understand the underlying mechanisms and to develop targeted therapeutic interventions that leverage the neurogenic potential of Semax in traumatic brain injury. [R]

ADHD and Anxiety

Limited studies have shed light on the specific use of Semax; however, the available evidence provides valuable insights into its potential benefits:

Semax has demonstrated prolonged stimulation of attention and short-term memory parameters, with observed positive effects persisting up to 24 hours after intranasal administration among test subjects. It has also shown significant improvements in memory and attention, particularly in healthy participants exposed to extreme activity conditions. Moreover, Semax exhibited anxiolytic and antidepressant effects in rats, possibly attributed to its ability to regulate BDNF levels, which are associated with depression severity. [R] [R]

Furthermore, Semax has shown promise in reducing anxiety levels in rats with toxic dopaminergic neuron damage and preventing functional impairments in avoidance responses. These findings collectively suggest the potential of Semax as a treatment option for conditions such as ADHD. While further research is needed, the existing evidence highlights the intriguing therapeutic possibilities of Semax in enhancing cognitive function and emotional well-being. [R]

How It Works

Semax exerts its mechanism of action in the brain through several key pathways. One of its primary effects is the rapid elevation of brain-derived neurotrophic factor (BDNF) levels and the upregulation of its signaling receptor, TrkB, specifically within the hippocampus.

Studies have demonstrated that Semax increases the concentration of both BDNF mRNA and protein in the hippocampus, thereby promoting neurotrophic effects. Additionally, Semax has been shown to induce an upregulation of TrkB expression in the dentate gyrus region of the hippocampus.

Furthermore, Semax modulates the dopamine and serotoninergic systems in the brain, which contributes to its overall cognitive effects. By enhancing the activity-dependent trafficking of AMPA receptors, Semax promotes the prioritization of neural circuits that are heavily engaged, leading to improved cognitive function.


When researching the use of N Acetyl Semax, it is essential to take certain precautions. Here are some precautions to keep in mind:

Observe best practices for studying research chemicals: Studying research chemicals requires a responsible and informed approach to ensure safety and meaningful scientific exploration.

Safety and Side Effects

Based on extensive research, Semax has demonstrated a high level of safety and tolerability among research participants, with minimal reported side effects. However, it is important to note that test subject responses may vary. Some test subjects have reported experiencing a mild burning sensation in the nasal passages or slight irritation of the mucus membranes after administration, although these effects are typically transient and temporary.

In addition, there are a few potential side effects that have been observed, albeit infrequently. These include headaches, nausea, vomiting, and drowsiness. It is worth emphasizing that these side effects are generally rare, and when they do occur, they are usually mild and self-limiting.


In conclusion, the possible benefits of using N-Acetyl Semax spray or powder have been extensively explored in various research studies. Studies conducted on rat brain focal ischemia have indicated the potential of N-Acetyl Semax in mitigating cognitive impairment and promoting neuroplasticity. Additionally, research on the immune and vascular systems has revealed the peptide’s ability to modulate these systems, suggesting potential therapeutic applications in related conditions. The investigation of N-Acetyl Semax peptide’s effects on the rat hippocampus and frontal cortex has shown promising correlations with genes associated with cognitive function, stress response, and default mode network activity.

Furthermore, the temporary dynamics observed in different stages of N-Acetyl Semax administration suggest its nootropic properties and potential efficacy in enhancing cognitive abilities. As scientists and researchers continue to focus on the development and evaluation of N-Acetyl Semax, its intended use in treating various conditions and determining its precise mechanisms of action remain important areas of exploration.
