What is Semax?

Semax is a synthetic peptide nootropic derived from a fragment of the endogenous adrenocorticotropic hormone (ACTH). Studies have shown its potential to improve cognitive function and support recovery in various brain-related conditions. More detailed information about the studies on the application can be found in the Research tab.

What is Semax Used for?

Semax is generally used to support brain health and mental function. According to the manufacturer, it may also be used in the following conditions, depending on the dosage:

Semax 0.1%:

  • Increase of attention and memory during repetitive and monotonous tasks;
  • Improvement of adaptive capacity of the human body in extreme conditions;
  • Cognitive impairments caused by cerebrovascular disorders, traumatic brain injuries, and neurosurgery;
  • ADHD.

Semax 1%:

  • Prevention and treatment of circulatory disorders and cognitive impairment, including after ischemic stroke;
  • Transient ischemic attacks;
  • Acute period of traumatic brain injury.

Please note that despite manufacturer recommendations, consultation with your attending physician is a must before taking any substances, including Semax neuropeptide.

What are the Benefits and Effects of Semax?

The main benefits and effects of Semax include:

Rapid Onset and Prolonged Effects

Semax delivers fast-acting results thanks to its intranasal delivery system. By bypassing the blood-brain barrier through perineural transport along the olfactory nerves, Semax reaches brain cells in under five minutes. Peak concentrations are typically achieved within 30 minutes, and its cognitive and neuroprotective effects can last for up to 24 hours.

Safety Profile

One of Semax’s most notable advantages is its tolerability. Clinical data from the manufacturer and user reports indicate that it has no known adverse interactions with other medications, making it a safe option.

User-Friendly Administration

Semax is available as a nasal spray, offering a non-invasive, painless, and highly convenient method of administration. This ease of use makes it a practical choice for individuals seeking consistent cognitive enhancement and neuroprotection without the need for injections or oral supplements.

Is Semax Safe to Take?

According to research published on the official website of the manufacturer, Semax is claimed to be safe. Still, there are several officially recorded Semax side effects, which are the possible irritation of the nasal mucosa and very rare allergic reactions. 

Reddit users have reported hair loss and thinning issues linked to Semax administration, though there’s no official data supporting this correlation. Potentially taking higher doses and employing administration routes other than authentic drops may also lead to hair loss. Additionally, concurrent use of other nootropics can contribute to elevated BDNF levels, causing hair issues over prolonged periods.

Biohackers about Semax

FAQ:

Where to Purchase Semax?

You can purchase authentic Semax nasal drops of the highest quality at CosmicNootropic, with worldwide shipping available. Other forms of Semax, such as N-Acetyl Semax, N-Acetyl Semax Amidate, and Adamax, may be available in other stores but are considered unconventional. For a product with a reliable safety-to-effectiveness ratio, it’s best to choose authentic nootropics and always follow your doctor’s recommendations.

How Many Packs of Semax Are Needed for a Full Course?

2 Bottles of Semax 0.1% are needed for a 2-week course.

How Does Semax Differ from Selank in Terms of Effects and Use Cases?

Semax and Selank are two distinct products. Although both are peptides administered nasally, their effects are quite different. Semax acts as a nootropic with mild stimulating properties, while Selank is primarily known for its anxiolytic (anti-anxiety) effects. If your goal is to improve focus and support faster learning, Semax may be the better choice. Selank, on the other hand, could be more suitable for those seeking stress relief, relaxation, and mood enhancement.

What Are the Correct Storage Conditions for Semax??

Store Semax drops in a dark place at temperatures below 10°C (50°F). Do not freeze. An opened bottle can be stored for up to six months without losing its properties, provided it is kept under the recommended conditions. The shelf life of an unopened bottle is 2 years.

Can Semax be kept at Room Temperature?

Semax can be kept at room temperatures below 30°C (86°F) for up to 30 days due to the inclusion of a safe preservative in its composition. However, exposure to direct sunlight is not recommended. For long-term storage, Semax should be kept in the refrigerator.

Will Semax Degrade or Lose Potency during a Delivery?

Semax is not likely to degrade during delivery under normal shipping conditions due to proper packaging and the built-in preservative. The product contains 0.01% methylparaben, a safe and widely used preservative that helps maintain its stability and extend shelf life. Moreover, Semax is produced in a sterile, GMP-compliant facility, which ensures high product quality and durability.

Is it Safe to Use Semax Drops in the Evening and Before Going to Bed?

It’s generally not recommended to use Semax after 5 p.m. due to its stimulating effects on nerve cells. As a neuropeptide, Semax helps regulate and normalize the sleep-wake cycle. However, this is not a strict rule, as individual tolerance to the drug can vary. If you don’t have trouble falling asleep when using Semax later in the evening, it is safe to use it after 5 p.m. when necessary.

Can Semax be used as a One-Time Coffee Alternative?

You can use Semax as a one-time coffee replacement to boost cognitive performance. For this purpose, the recommended dosage of Semax® 0.1% is 3 drops in each nostril, taken twice in the morning with a 15-minute interval. For optimal effect, it is advisable to take an additional dose later in the day if needed.

How Can Semax Help During Finals or Exams and How to Take It?

The primary effect of Semax is enhanced mental performance. It stimulates all three key processes of memory: encoding, storage, and recall, which is why it's commonly used by students. For best results, it's recommended to begin using Semax 0.1% 10 days before your finals or exams. The recommended dosage is 3 drops in each nostril, taken twice a day for 10 days.

Can I use Semax Every Day for a Long Period of Time?

Semax is not intended for long-term daily use, and official guidelines recommend limiting continuous administration to a 10–14 day course. It can also be used sporadically for a single day as a substitute for coffee. 10- to 14-day duration also applies when Semax is used for conditions such as strokes, traumatic brain injuries, and other severe conditions. Even in cases of severe stroke, the recommended duration is 10 days.

Is Semax legal in the US, UK, and Australia?

Semax is not approved by the FDA and cannot be purchased in pharmacies or drug stores in the US, UK, or Australia. However, it can be legally obtained for personal use in small quantities from online stores or in other countries. In most cases, there are no issues with customs when shipping nootropics like Semax.

Why is Semax Delivered in the Form of Nasal Drops?

Semax is formulated as nasal drops because the developers believe that intranasal administration is the most effective method for treating brain-related conditions. By passing through the nasal mucosa, the active ingredient reaches the brain quickly via the olfactory nerves, which directly connect to the brain and bypass the blood-brain barrier. This is why Semax begins to take effect rapidly.

What Is the Mechanism of Action of Semax?

Semax works by breaking down into its constituent peptides, such as the Met-Glu-His-Phe tetrapeptide and the Pro-Gly-Pro tripeptide, when acted upon by aminopeptidase enzymes. These peptides then exert their therapeutic effects by acting as catalysts for natural biological processes. Over time, these peptides are further broken down into individual amino acids, which are naturally incorporated into metabolic processes in the body. Rather than replacing the body's natural molecules, Semax helps stimulate the synthesis of these peptides within neurons, effectively promoting the body’s own peptide production. This mechanism helps reset the cycle of endogenous peptide synthesis in the central nervous system (CNS), supporting the restoration of natural processes and enhancing brain function.

Can I Use Semax Along With Drinking Alcohol?

Semax does not directly interact with alcohol, so it is generally considered safe to use both together. However, when taking Semax, alcohol intoxication may be delayed and occur later, especially with higher alcohol doses. Additionally, Semax may help reduce the symptoms of alcohol intoxication the following morning, such as hangover effects.

Is Semax Classified as a Peptide?

Semax is classified as a synthetic heptapeptide derived from the ACTH (adrenocorticotropic hormone) fragment and belongs to a group of bioregulator peptides.

 

What is the Dosage of Semax?

The standard Semax dosage is 2 drops in each nostril, administered 1–2 times per day depending on the regimen.

Course Duration:

Use for 3 to 14 days depending on the regimen.

Bottle Yield:

One bottle contains 70–75 drops (each drop delivers 50 mcg of Semax), which is typically enough for 3–10 days of use.

Note:

For a faster onset and a more pronounced effect, a second dose can be taken 15 minutes after the first one.
Using a higher-concentration Semax does not always enhance results.

What are the Side Effects of Semax?

Officially recorded side effects include possible irritation of the nasal mucosa and, in very rare cases, allergic reactions. Some users on platforms like Reddit have reported hair thinning or hair loss associated with Semax use, although there is no clinical data confirming this link. These effects might be influenced by prolonged usage, high dosages, using forms other than the authentic nasal drops, or combining Semax with other nootropics, which could elevate BDNF levels and potentially affect hair health over extended periods.

Semax

The drops do not work. You have to snuff them up but they fall right out. There is no good way to absorb the drops. It should be a spray or other method of delivery. I feel it was a waste of money to get the drops.

03/02/2025

CosmicNootropic

Sorry to hear you’re having trouble with the drops. Semax is designed to be absorbed through the nasal mucosa, and while it’s not a spray, tilting your head back slightly after administering can help with absorption. If you have any other concerns, feel free to reach us out at [email protected] — we’re happy to help!

I bought this product because it was on sale do to being at the USA border too long according to the website, but when the tracking number was provided it was coming from Russia instead of the USA as advertised. The product smelled like fried bacon and yet I used it and little to no effects took place. I will not order it again if it sits to long again.

selank drops

I want start off by saying I really appreciate you guys for having the items I needed, always in stock, and discrete packaging. I got the semax drops, using this protocol: 2 drops per nostril, once in the morning, and again in the evening. I felt a noticeable difference by week two. Felt less foggy in the morning and I really like the calmness factor it provided me, especially during my long study hours. I didnt like the dropper because of the tip shape, but overall great product. Definitely met my expectation for increasing mental endurance. Ordered both the semax and selank nasal drops and they arrived within the week! 100% satisfaction on the first few purchases. Will be checking out other neutropics.

Semax - Fantastic Product from Terrific Company!

I\'ve been using the majority of classical nootropics for over 15 years. Most racetams, especially pramiracetam and phenotropil, as well as modafinil and its analogues and metabolites, other substances like Bromantane, PRL 8-53, oxazolidinones, you name it. All of them to some degree help to focus, provide additional mental energy, improve multitasking, auditory and visual perception and working memory. I have tried an american-made N-Acetyl-Semax some years ago, but it (or perhaps that particular batch) didn\'t have much effect on me. I kept on reading about development of newer peptides which boosted BDNF, and finally I decided to turn to Semax in its original form. There is Semax made in US that you could buy online, but since Semax was originally developed in Soviet Union, I decided to buy it from Cosmic Nootropic, which sells a version manufactured in one of the countries that used to be a part of USSR. The process of ordering online with a credit card was straightforward. I had some additional questions about my account and sent Cosmic Nootropic an email. It was promptly answered the next day. It was the warmest, most personal email I have ever received from a vendor\'s customer support. I pay attention to such things and its tone genuinely touched and delighted me. The next day I received an order tracking number and my order arrived in about 4 days, which was great. Everything was professionally packaged. Each bottle of Semax was inside original packaging, which also contained a rather unique super precise dropper in its own ziplocked packet and the original manufacturer printout describing the medication. My only misgiving was that there is no plastic seal covering the bottle cap, which is a common practice in US for liquid medication. But this is probably how the original manufacturer packages it and is outside of Cosmic Nootropic control. Now about Semax effect. As a senior professional software developer, I have to study new information on daily basis. Normally I have to reread explanations of complex functionality or re-watch parts of the videos, before the information is fully absorbed. While other nootropics made that somewhat easier, nothing could prepare me for what Semax did. When I was in school, up to a certain point in time, when a teacher was deriving an equation on a black board, most of the other kids were copying his results to their notebooks, but I could simply kind of follow along, deriving the equation myself without looking at the black board. I didn\'t think much about it. Much later, when I lost that ability, probably due to alcohol consumption, I realized that in those moments I was in a kind of an extremely quiet, comfortable happy place, in a total state of relaxation and the answers would come to me effortlessly. Note that it was a happy place and not a \"Zone\" or state of Zen that one can get into with Modafinil or Adderall. And that\'s what Semax did after 3 weeks! No stimulation whatsoever, no push, but some sort of quiet pseudo time dilation which gives me time to absorb the information without stressing out from trying to focus. Note that this is not the kind of time dilation that occurs with psychedelics. I am aware of time passing in a normal way, its just as if my brain was somehow given more time to process information internally. The overload is gone as if I gained multiple brains. It also affects the senses, the world feels closer, quiet sounds are more distinct, I almost feel them with my skin. The state of NOW, fully living in the present. This is how I perceived the world when I was a child and I assume that this is exactly what scientists mean when they speak gain plasticity! By the way if anybody wonders, I was never diagnosed with ADHD, but I can understand now how this agent could help anyone with diminished executive function, derealization, etc. Having had this tremendous success with Semax, it is temping to try other newer BDNF substances that Cosmic Nootropic carries, but there is a significant risk experimenting with new substances. And Semax has been around for a long time. Yes, you might have to use topical minoxidil and finasteride, if you are one of those who is subjected to enhanced hair loss from Semax, but I think its worth it. It is medically accepted that all BDNF agents might cause hair loss, but the enhanced brain function theoretically should bring extra income to deal mediate it. Back to Cosmic Nootropic. The company goes out its way to help its customers. They have published the most complete guide on Semax on the web. Kudos to them for all that they have done!

Great company

After so many changes in the nootropic company finding these guys has been amazing! Super good communication and great products plus very fast shipping! I would definitely do business again!

I have no idea what is happening and I can’t pin it down to your drugs.

It was ok. I would have more confidence in your product if i can please visit you and chat with you about how this thing works. It would be very appreciated. Please email me at [email protected] to arrange a consultation, or ask random people you know until one of them recognises me and can help you find me, since that seems to be the world we are cascading into over and over again.

Semax is perfection

Amazing! Works perfectly, and instantly. Definitely recommend 10/10; can’t say that for most products.

A fantastic nootropic. A amazing company.

Selank for me has been a great experience. It calms down my thoughts, and makes it easier to digest information. The substance itself feels very subtle, but has profound positive mental effects. I would suggest that anyone who has trouble studying to give it a try. It is also great after a rough day to relax. Dealing Cosmic Nootropic has been nothing but pleasurable. Very fast delivery to the united states, and discounts for using bit coin. On top of that they provide almost near instant updates on the status of your package. Going even further. Will notify you, and confirm the delivery of it. They go even further by making sure you are totally satisfied with the products once delivered. I have never had a more positive, and detailed experience ordering anything.
