Product Description

What is Semax?

Semax is a new neuroprotective peptide, which is derived from the molecular structure of adrenocorticotropic hormone (ACTH), is a natural substance found in the human body, also known as MEHFPGP. It was developed by a Russian research team from the Institute of Molecular Genetics, initially, it was pursued as a treatment for stroke victims suffering brain damage. However, Semax also has similar history, potency, and chemical makeup to Noopept powder. In Russia and Ukraine, Semax is approved to use to prevent and treat circulatory disorders, it often is marketed as a “nootropic” or a “smart drug” and is believed to improve cognitive function and memory. However, in the U.S.A, Semax serves as a base component for a number of pharmacological products, that use to treat in clinical practice for the treatment of CNS diseases (ischemic brain stroke,dys-circulatory encephalopathy, optic nerve atrophy, etc).

Semax is typically administered as a nasal spray or subcutaneous injection and has poor oral bioavailability. Its usage and dosage regimen varies depending on the specific condition for treatment. If you are considering buying a peptide of Semax powder or finished vials online, a reputable supplier is an especially important option, that can ensure you get the quality of peptide Semax. And, AASraw can supply high-quality peptides with the support of the independent R&D center and factory, Semax wholesale orders are acceptable.[1][2]

How does Semax work

Semax works through multiple mechanisms to promote various aspects of brain function and health, following are some of the proposed ways that Semax may exert its effects:

(1)Neurotrophic factor modulation

Semax enhances the levels and activity of brain-derived neurotrophic factor (BDNF) and can promote the growth, development, and survival of neurons, to help to learn and improve memory.

(2)Dopaminergic system modulation

Semax affects the dopamine system in the brain, can promote to release of dopamine, and enhances dopamine receptor sensitivity, leading to improve cognitive functions and mood regulation.

(3)Anti-inflammatory and antioxidant effects

Semax exhibits anti-inflammatory properties by reducing the production of pro-inflammatory molecules and promoting the release of anti-inflammatory substances. It also acts as an antioxidant, protecting neurons from oxidative stress and damage caused by free radicals.[6][3]

(4)Neuropeptide modulation

Semax can influence the levels and activity of various neuropeptides, it may contribute to pain relief, anti-inflammatory effects, and immune system modulation by regulating these neuropeptides.

(5)Neuroprotective effects

Semax has shown neuroprotective properties by enhancing neuronal survival, reducing neuronal apoptosis (cell death), and promoting neuronal recovery and regeneration. It helps protect neurons from damage and supports their overall health and function.

(6)Cognitive enhancement

Semax can enhance synaptic plasticity, help to strengthen or weaken in response to neural activity and lead to improving cognitive performance.

It’s important to note that Semax research is still ongoing, there are many of its exact mechanisms and effects are not yet fully understood.[1][6] But, in the current market, Semax is mainly sold as a “cognitive enhancer” and “neuroprotective agent”, which is one of the best nootropics supplements.[7]

The potential benefits when you using Semax

Semax is a nootropic drug that has been shown to offer many potential benefits and uses in various areas, following is researcher reported benefits:

①Improve attention and memory: Some users have reported improvements in attention span and memory abilities while using Semax.

②Reduced anxiety and depression symptoms: Semax has been reported to have mood-regulating effects, potentially reducing symptoms of anxiety and depression.

③Improved mental clarity and focus: Users have described an increase in mental clarity and focus with Semax use.

④Reduced effects from stress: Semax may have the ability to mitigate the negative effects of stress on the body and promote a sense of calmness.

For Medical Conditions when Semax use for treatment

①Anxiety disorder: Semax has been prescribed for the treatment of anxiety disorders, although more research is needed to establish its efficacy.

②Ischemic events and stroke: Semax has been investigated for its potential to aid in stroke recovery and reduce damage caused by ischemic events.

③Nerve regeneration: Semax has shown potential in promoting nerve regeneration and repair.

④ADHD: Semax has been used as an alternative treatment for ADHD, although its effectiveness in this regard requires further investigation.

⑤Opioid withdrawal: Semax has been explored as a potential aid in managing withdrawal symptoms during opioid addiction treatment.

⑥Chronic diseases such as ALS, Parkinson’s Disease, and Alzheimer’s: Semax has been studied in preclinical models and shows promise in potentially improving symptoms and disease progression in these conditions, but further research is needed.

⑦Thrombosis: Semax has been investigated for its potential in preventing and treating thrombosis, although more research is necessary to establish its effectiveness.

⑧Gastric issues: Semax has been explored for its potential in the treatment of gastric-related disorders, but clinical evidence is limited.

What is the side effect of Semax?

As some research and user reports, Semax is generally considered to be safe and well-tolerated. However, like any substance, Semax may have potential side effects. It’s important to note that individual responses to Semax can vary, and not everyone may experience these side effects. Here are some potential side effects associated with Semax:

▪ Hair loss
▪ Nausea
▪ Vomiting
▪ Headaches
▪ Mild fatigue
▪ Restlessness
▪ Nasal irritation
▪ Allergic reactions
▪ Sleep disturbances
▪ Changes in appetite
▪ Increase in blood sugar levels

It’s worth noting that Semax has been extensively studied in Russia and used in clinical practice for several years, with a relatively good safety profile. But, if you’re a new user with Semax, usually not advise work Semax stack with other nootropics or supplements, that might increase the risk of adverse side effects. If you insist to do this thing, you’d better consult with a healthcare professional before using it.

Semax VS Selank: Similarities and Differences

Semax and Selank are both peptide drugs with potential cognitive and mood-enhancing effects, but they have different mechanisms of action and applications. Here’s a comparison between Semax and Selank:

(1)Mechanism of Action:

Semax: Semax is derived from a peptide called adrenocorticotropic hormone (ACTH). It works by modulating the levels of neurotransmitters such as dopamine, serotonin, and norepinephrine in the brain. Semax primarily acts as a neuroprotective and cognitive-enhancing agent.

Selank: Selank is a synthetic peptide that is based on a fragment of the peptide Tuftsin. It acts as an anxiolytic and antidepressant by regulating the levels of stress-related hormones, such as cortisol. Selank also affects the levels of neurotransmitters, including serotonin.

(2)Effects and Benefits

Semax: Semax is known for its potential benefits in improving cognitive functions such as attention, memory, and focus. It may also help reduce symptoms of anxiety, depression, and stress. Semax has been studied in conditions such as stroke, ADHD, and neurodegenerative diseases.

Selank: Selank is primarily used for its anxiolytic and antidepressant effects. It may help reduce anxiety symptoms, promote relaxation, and improve mood. Selank has been studied in anxiety disorders, depression, and post-traumatic stress disorder (PTSD).


Semax: Semax is commonly available as a nasal spray and is administered intranasally.

Selank: Selank is also available as a nasal spray, but it can also be injected subcutaneously.

(4)Safety Profile

Semax: Semax is generally considered to be safe and well-tolerated, with few reported side effects. Commonly reported side effects include mild nasal discomfort, headaches, and transient irritation.

Selank: Selank is also considered to have a good safety profile, with few reported side effects. Some users may experience mild nasal discomfort or headaches.

Semax Testing Report-HNMR

What is HNMR and What does HNMR spectrum tell you? H Nuclear Magnetic Resonance (NMR) spectroscopy is an analytical chemistry technique used in quality control and research for determining the content and purity of a sample as well as its molecular structure. For example, NMR can quantitatively analyze mixtures containing known compounds. For unknown compounds, NMR can either be used to match against spectral libraries or to infer the basic structure directly.[1][6] Once the basic structure is known, NMR can be used to determine molecular conformation in solution as well as studying physical properties at the molecular level such as conformational exchange, phase changes, solubility, and diffusion.
