Semax (ACTH 4-7 analog) 0.1% nasal spray
Semax is for adults who want to think more clearly: professionals and students under sustained mental load, people with brain fog or scattered attention, anyone whose memory feels slower than it used to, and people who want cognitive support without stimulants. It is often paired with NAD+ for energy and focus, and it suits anyone who prefers a nasal spray to an injection.
It is not for use during pregnancy or breastfeeding. Tell your provider about antidepressants, ADHD medication, blood-pressure medication, seizure history, and anything else you take. Your provider reviews your history during the online visit.
No insurance, no membership fees, no auto-renewal.
Your brain maintains and rewires itself using growth factors, chiefly brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF). Semax raises their production: in animal studies BDNF expression in the hippocampus, the brain's memory center, increased three- to four-fold. That supports synaptic plasticity, the strengthening of connections that underlies learning and memory, and it protects neurons under stress by reducing oxidative damage and inflammation in neural tissue. Semax also modulates dopamine and serotonin turnover, which is why people describe the effect as steadier mood and attention rather than stimulation.
Because it is sprayed into the nose, Semax is absorbed through the nasal lining and reaches the brain quickly, bypassing digestion that would destroy it. In Russia it is approved for stroke recovery, optic nerve atrophy, and attention disorders, with Phase III trials reporting improved neurological outcomes after ischemic stroke. Most of that research is Russian and has not been replicated in large U.S. trials; your provider will be candid about what that means.
Your provider sets your dose, typically one to two sprays per nostril two to three times a day for a total of 200 to 600 mcg daily, taken in a course of 10 to 14 days followed by a two- to four-week break. That cycle mirrors how Semax is prescribed clinically in Russia and helps the effect stay fresh. Many people take the last dose by early afternoon, since late dosing can feel alerting.
The spray is stored according to the pharmacy label, usually refrigerated. No needles are involved. Your provider reviews your response after the first course and plans the next one.

Join the GobyMeds communityDays 1–3. Because the spray is absorbed quickly, many people notice sharper, calmer focus within the first few days of a course.
Days 4–14. Mental stamina, recall, and resilience to stress typically build through the course as neurotrophic factors rise.
The break. Benefits often carry into the two- to four-week pause between courses; this is also when your provider reviews how the first course went.
Ongoing. Semax is used in repeated courses rather than daily forever. A typical path, not a promise; your provider adjusts the schedule with you.
Side effects are rare and mild: nasal irritation or dryness, occasional headache, or restlessness if a dose is taken late in the day. More than twenty years of clinical use in Russia, including in children, have not identified serious safety signals, and no liver, heart, or kidney toxicity has been reported, though controlled U.S. data are limited. Semax has no reported dependence, tolerance, or withdrawal. Compounded Semax is not FDA-approved. Report side effects to your care team and to the FDA at 1-800-FDA-1088.
Do not use Semax if you are pregnant, planning a pregnancy, or breastfeeding, or if you have a known allergy to the formulation. Tell your provider about psychiatric medication, a history of seizures, uncontrolled blood pressure, and all medications and supplements you take. Compounded drug products are not approved or evaluated for safety, effectiveness, or quality by the FDA. Prescription only; not available in all states.

Semax is a seven-amino-acid peptide derived from a fragment of the hormone ACTH, modified so it acts on the brain without affecting cortisol or the adrenal glands. It has been a prescription nasal medication in Russia since 1996, used for stroke recovery, optic nerve conditions, and cognitive impairment, and it is one of the most-studied cognitive peptides. At GobyMeds it is prescribed as a compounded nasal spray prepared by a licensed U.S. pharmacy. It is not FDA-approved.
Most patients ask about Semax for focus, memory, mental stamina, and brain fog, and for support during high-stress periods. In Russia it is approved for stroke recovery, optic nerve atrophy, and attention disorders; the FDA advisory committee reviewed it in 2026 for cerebral ischemia and trigeminal neuralgia. Most of the clinical research is Russian, and your provider will be candid about what it does and does not show.
Semax is sprayed into the nose, typically one to two sprays per nostril two to three times a day, for a total of about 200 to 600 mcg daily. It is usually taken in courses of 10 to 14 days followed by a two- to four-week break, which is how it is prescribed in Russia. Your provider sets your dose and course length. No needles are involved.
No. Semax does not work on dopamine release the way caffeine or amphetamines do. It raises brain-derived neurotrophic factor (BDNF) and related growth factors that support neuron health and connections, so the effect most people describe is clearer, calmer focus rather than a buzz, with no reported tolerance, crash, or withdrawal.
Semax has few known interactions, but tell your provider about antidepressants, ADHD medication, blood-pressure medication, and anything else you take so they can review the combination. It is often prescribed alongside NAD+ for energy and focus.
Side effects are rare and mild: nasal irritation or dryness, occasional headache, or restlessness if taken late in the day. More than twenty years of clinical use in Russia have not identified serious safety signals. It is not prescribed during pregnancy or breastfeeding. Compounded Semax is not FDA-approved.
Because it is absorbed through the nose, Semax reaches the brain quickly; many people notice sharper focus within the first few days of a course. Benefits for memory and mental stamina build over the 10- to 14-day course and often carry into the break between courses. Your provider will adjust the schedule based on your response.
Peptides are short chains of amino acids, the same building blocks that make up proteins. Your body already makes thousands of them to carry signals between cells: to start repair after an injury, to release growth hormone during sleep, to calm inflammation, or to tell your mitochondria to make more energy. Peptide therapy uses lab-made copies or fragments of those signals, prescribed at a specific dose, to support a process your body already knows how to run. Semaglutide and tirzepatide are peptides too, which is why GobyMeds already has years of experience prescribing and shipping them.
Compounded peptides are not FDA-approved, and no compounded medication is. In July 2026 the FDA's Pharmacy Compounding Advisory Committee voted to recommend adding BPC-157, KPV, TB-500, MOTS-c, Semax, and Epitalon to the list of substances that licensed 503A pharmacies may compound, and in October 2026 HHS published an interim enforcement-discretion policy covering those six peptides while the FDA completes formal rulemaking. GobyMeds offers a peptide only when a licensed U.S. pharmacy can lawfully compound it for your prescription under that policy and your state's rules. Compounded drugs are not evaluated by the FDA for safety, effectiveness, or quality.
Yes. Every peptide at GobyMeds is prescription-only. You complete a short online visit, a licensed U.S. provider reviews your history and goals, usually within one business day, and prescribes the peptide only if it is appropriate for you. The pharmacy then compounds it for your prescription and ships it to your door. If a provider decides treatment isn't right for you, you receive a full refund.
Websites selling "research use only" peptides ship unregulated powders with no prescription, no provider, no sterility testing you can verify, and no one to call when something feels off. GobyMeds is LegitScript-certified: a licensed provider evaluates you first, a licensed U.S. compounding pharmacy prepares your medication to a prescription, and your care team follows up with you throughout. You also get transparent pricing, a supply kit with instructions, and free shipping, with no membership fee.
Most peptides are broken down in the stomach, so the most reliable route is a small injection under the skin with a tiny insulin-type syringe, the same kind used for GLP-1 weight-loss medication. The needle is very fine, the volume is small, and most people say it is easier than expected after the first time. Your kit includes syringes, alcohol swabs, and step-by-step instructions, and your care team can walk you through the first dose. Semax is the exception: it is a nasal spray.
Often, yes. Peptides are frequently prescribed alongside each other (BPC-157 with TB-500 for recovery, for example) and alongside GLP-1 medication, NAD+, sermorelin, or testosterone therapy. Tell your provider about everything you take, including supplements, and they will coordinate the plan and the timing. Your provider will work with you to adjust your medication for your goals.
No lab work is required to start. Your provider reviews your health history during the online visit and may ask for recent results if something in your history warrants it. For a few peptides your provider may suggest baseline bloodwork so progress can be measured, for example fasting glucose or inflammatory markers; that is optional and you can use your own doctor's results.
Your medication ships free from the pharmacy in insulated, cold-chain packaging in as little as 3 days after provider approval; most orders arrive within two to five business days. Injectable peptides arrive as a sterile vial, either ready to use or as a powder with the water needed to mix it, and should be kept in the refrigerator. Nasal sprays are stored according to the label. Full storage and mixing instructions are in your kit and in the patient portal.
Each peptide page shows its plan prices up front. The price you see is the price you pay: it includes the online visit, provider follow-ups, the medication, your supply kit, and shipping. There is no membership fee, no insurance requirement, and no auto-renewal, and you are not charged until your medication ships.
The peptides GobyMeds offers are copies or fragments of molecules your body already makes, and most people experience few side effects. The most common are mild and temporary: redness or a small bump at the injection site, brief flushing, headache, or nausea. Human research on most peptides is still limited, which is why a provider screens your history first and why we are candid about what the evidence does and does not show. Compounded peptides are not FDA-approved. Report side effects to your care team and to the FDA at 1-800-FDA-1088.
If a GobyMeds provider decides a prescription isn't appropriate for you, you receive a 100% refund of the medication price (lab fees, where they apply, are not refunded). Once your order has been sent to our medical partners or to the pharmacy for fulfillment we will do our best to accommodate changes or cancellations, but we can't guarantee them, and in some cases an adjustment or cancellation carries a $50 medical consultation fee.
Because of regulations covering prescription medication, we are unable to accept returned medication for a refund.
No insurance is needed and GobyMeds does not bill insurance. The price you see is the price you pay, with provider consultation and shipping included and no membership fee.
HSA and FSA cards are accepted at checkout, and we can provide a letter of medical necessity if your plan administrator asks for one.
You answer a short health questionnaire and upload a photo ID. A licensed U.S. provider reviews your history, usually within one business day, confirms the treatment is appropriate, and writes the prescription. There is no video call to schedule unless your provider or your state requires one, and unlimited follow-up messaging with your care team in the patient portal is included with every plan.
If you're not a candidate, you'll be told why and refunded in full.
