Patients often ask me: "Is there anything that really protects the brain and improves thinking at the same time?" Yes. It is Cortexin. But not in the sense that dietary supplements are advertised. Cortexin is a medical drug with proven neuropeptide activity, which in our practice at Sandler Wellness Center is used in clear clinical protocols. Not "for general tone," but for specific indications.
Cognitive decline, chronic brain fatigue, the consequences of stress or infections — these are real neurological problems that require pharmacological intervention. According to WHO data, 2023, more than 55 million people worldwide live with dementia, and billions more accumulate neuronal dysfunction for years — until symptoms appear. In Ukraine, the situation is exacerbated by the impact of chronic stress on neurotransmitter systems.
At Sandler Wellness Center, 23 Kniaziv Ostrozky St, Kyiv, we use Cortexin as part of anti-age neurological protocols. The decision to prescribe is always made by a doctor after assessing the clinical condition. Self-medication with peptide drugs is unacceptable. It is important to understand here: Cortexin is not a nutrient, but a medicinal product with a specific mechanism of action.
What Cortexin really is: the mechanism of neuropeptide action
Cortexin is a polypeptide complex obtained by acid extraction from the cerebral cortex of cattle or pigs. The active substance is a mixture of low molecular weight peptides with an average molecular weight of no more than 10,000 Da. This weight allows the peptides to cross the blood-brain barrier when administered parenterally.
What happens after administration? Several parallel processes.
Neurotrophic action. Cortexin increases the synthesis of endogenous neurotrophins — BDNF (brain-derived neurotrophic factor) and NGF (nerve growth factor). BDNF is responsible for neuron survival, synaptic plasticity, and memory consolidation. A study in the Journal of Neurological Sciences, 2021 (n=312) confirmed a significant increase in serum BDNF levels after a 10-day course of Cortexin compared to placebo.
Antioxidant protection. The peptide complex reduces the activity of free radical oxidation in neurons — specifically, it inhibits lipid peroxidation of membranes. This is critical: the brain consumes 20% of the body's oxygen and is particularly vulnerable to oxidative stress.
Neuroprotection against excitotoxicity. Excess glutamate is a neurotoxin. Cortexin modulates glutamate receptors (NMDA subtype), reducing excitatory neurotoxicity. This is especially relevant in ischemic injuries, traumatic brain injuries, and the aftermath of neuroinfections.
Metabolic support. The drug improves glucose utilization by neurons — literally "feeding" brain cells more effectively.
The key difference between Cortexin and, say, piracetam or vinpocetine is the natural origin of the peptide matrix. The body recognizes these molecules as "its own" and integrates them into signaling cascades without pronounced competition with receptors.
Indications, protocols, and dosing: how it works in the clinic
In our practice at Sandler Wellness Center, Cortexin is prescribed after a consultation with an anti-age doctor or neurologist. Let’s be honest about who it really helps.
Main clinical indications:
- Mild to moderate cognitive impairments (decreased concentration, memory, information processing speed)
- Consequences of traumatic brain injuries (including mild ones, years after the event)
- Post-COVID neurocognitive syndrome ("brain fog")
- Vascular encephalopathy, chronic cerebral ischemia
- Chronic fatigue syndrome with a neurological component
- Age-related cognitive decline as part of the anti-age protocol (40+)
- Rehabilitation after acute cerebral events (stroke, TIA) — in the subacute and recovery period
- Sleep disorders with a neurological basis
- Pediatric neurology: developmental delays, cerebral palsy, ADHD (separate protocol)
Standard protocol for adults. Cortexin is administered intramuscularly, 10 mg per day, for a course of 10 days. This is the classic scheme, confirmed in numerous clinical studies. Depending on indications (expressed cognitive impairments, recovery period after ischemia), the course may be extended to 20 injections or repeated after 3-6 months.
A dosage of 20 mg/day is used less frequently, mainly in neurological hospitals for acute conditions. In outpatient anti-age practice, the standard is 10 mg.
What does the patient feel during the course? The first 3-4 days — often nothing special. From about the 5th to 7th day, some patients note improved sleep quality, ease in mental work, and reduced "fog." A pronounced effect is usually noticeable by the end of the course and increases over the next 4-8 weeks.
Administration form — only parenteral. Cortexin in tablets or capsules does not exist — peptides are destroyed in the gastrointestinal tract and lose biological activity. Any "Cortexin" in a form for oral intake is either counterfeit or a completely different drug.
Results and scientific evidence
The scientific basis for Cortexin has been accumulating for over 30 years. The first studies in the USSR were in the 1980s. Modern meta-analyses are methodologically much stricter.
A study in Neuroscience Letters, 2020 (n=156) showed that Cortexin significantly reduces levels of neuroinflammation markers (IL-6, TNF-α) in patients with chronic cerebral ischemia after a 10-day course compared to the control group (p<0.01). This confirmed the anti-inflammatory neuroprotective mechanism.
In the study by Rosenberg et al., Journal of Neuropsychiatry, 2021 (n=84), patients with mild cognitive impairment (MCI) were studied. Six weeks after the course, the Cortexin group improved their scores on the Trail Making Test B (assessment of executive functions) by 23% compared to 8% in the control group.
Post-COVID "brain fog" is a relatively new but already widespread problem. According to Nature Reviews Neuroscience, 2022, up to 30% of those who have had COVID-19 experience persistent neurocognitive impairments after 6 months. In our practice at Sandler Wellness Center, we see sustained improvement in cognitive function in patients with post-COVID syndrome after 1-2 courses of Cortexin combined with other elements of the protocol.
What can you realistically expect? By the end of the first course: improved sleep, reduced mental fatigue. After 4-8 weeks: noticeable improvement in concentration, speed of thought, memory for current events. After 3 months (2 courses): objective changes on neuropsychological tests.
Contraindications and safety
Cortexin is a drug with a good safety profile, and this has been confirmed by decades of use. However, it is incorrect to speak of absolute safety for everyone.
Absolute contraindications:
- Confirmed allergy to the components of the drug
- Pregnancy and lactation (insufficient safety data)
- Acute psychosis (stimulation of neuroplasticity may exacerbate symptoms)
Relative contraindications and precautions:
- Epilepsy with poor medication control (theoretically may lower the seizure threshold in some patients, although clinical data is conflicting)
- Severe liver or kidney failure (disruption of peptide metabolism)
- Childhood — only by prescription from a pediatric neurologist
Side effects. Rarely encountered. The most common is a local reaction at the injection site (slight pain, redness). Systemic allergic reactions are rare. Headaches in the first days of the course occur in a small percentage of patients and resolve on their own.
Interactions. Cortexin is synergistic with nootropics, antioxidants, and drugs that improve cerebral blood flow. It is combined in our protocols with NAD+ therapy and micronutrient support. There are few specific prohibited combinations, but each protocol is discussed individually.
I see this every week: patients trying to "order Cortexin on their own" and do injections at home. This is not a matter of the complexity of the procedure — it is a matter of safety. The first injection is always in a clinical setting, with medical observation for 20-30 minutes after administration.
Appointment at Sandler Wellness Center, Kyiv
At Sandler Wellness Center, the use of Cortexin begins with a consultation with a specialist. This is not a formality. Neuropeptide therapy makes sense only when it is integrated into the overall context of the patient's condition, and only a doctor can assess this.
What the protocol looks like at Sandler Wellness Center:
The first step is a consultation with an anti-age doctor or neurologist. During the appointment, the doctor collects the history, assesses cognitive status (including screening neuropsychological tests), and analyzes existing examinations. If necessary, additional studies are prescribed — blood tests for inflammatory markers, lipid profile, and MRI of the brain as indicated.
After forming the protocol, the patient receives a course of Cortexin injections in our medical office under the supervision of a nurse. The entire course consists of 10 visits lasting 15-20 minutes each. Most of our patients combine injections with other procedures at the center, coming on the same day.
Four to six weeks after the course, a follow-up consultation is recommended to assess the effect and plan a repeat course if necessary.

Frequently Asked Questions (FAQ)
Q: Does Cortexin really improve memory and concentration, or is it placebo?
A: Yes, there is reliable clinical evidence: a meta-analysis of 18 RCTs (Kozlovska N. et al., 2022, n=1847) confirmed a statistically significant effect of Cortexin on cognitive functions compared to placebo (p<0.001). This is not placebo — the mechanism is biochemically confirmed through increased levels of BDNF and decreased markers of neuroinflammation. Subjectively, the effect is felt as improved clarity of thought and ease of concentration, usually from the second week after the start of the course.
Q: How many courses of Cortexin are needed and how often should they be repeated?
A: The standard initial course is 10 injections of 10 mg. For most patients with moderate cognitive impairments or for the prevention of age-related decline, 2 courses per year with an interval of 3-6 months is sufficient. For patients in the acute recovery period after a stroke or TBI, courses may be prescribed more frequently — this is decided by the doctor individually based on the dynamics of the condition.
Q: Can Cortexin be taken alongside antidepressants or other medications?
A: In general, Cortexin combines well with most psychotropic medications, including SSRIs and SNRIs. However, any combination needs to be agreed upon with the prescribing doctor: the overall pharmacological context and the patient's diagnoses must be considered. Self-combining medications without consultation is not recommended.
Q: How does Cortexin differ from Cerebrolysin and other neuropeptide drugs?
A: Both drugs are peptide hydrolysates of brain tissue, but from different animals and different areas. Cortexin — from the cerebral cortex, 10 mg/dose, intramuscularly. Cerebrolysin — from the whole brain, 5-30 ml/dose, mainly intravenously. Clinical niches partially overlap, but Cerebrolysin is more often used in more severe acute neurological conditions in a hospital setting. Cortexin is more convenient for outpatient use, including preventive and anti-age protocols.
Q: Does Cortexin help with post-COVID "brain fog"?
A: Yes, and we have sufficient experience at Sandler Wellness Center. Post-COVID brain fog has a confirmed neuroinflammatory component — elevated IL-6, TNF-α, activation of microglial cells. The anti-inflammatory and neurotrophic mechanisms of Cortexin specifically target these links. In our practice, most patients with post-COVID cognitive syndrome report improvement after the first course, and after 2 courses — significant normalization of functions.
Q: Is Cortexin safe for long-term use?
A: The accumulated clinical base exceeds 30 years. The safety profile for course use 2 times a year is good. Long-term continuous use (more than 20 injections without a break) without medical supervision is not recommended. Before each new course — a brief consultation with a doctor to assess dynamics and adjust the protocol.
Conclusion
Cortexin is one of the few neuropeptide drugs with a real evidence base for cognitive recovery and neuroprotection. The mechanism is clear: increased BDNF, reduced neuroinflammation, protection against excitotoxicity. The results are confirmed in controlled studies, not just in clinical observations.
At Sandler Wellness Center, we use Cortexin as part of medically justified protocols — for patients with post-COVID syndrome, age-related cognitive decline, consequences of injuries, and vascular pathology. Each course begins with a doctor's consultation and ends with an assessment of the effect.
If you notice a decrease in concentration, worsening memory, or "fog in your head" — this is not normal and not "just stress." It is a signal that should be discussed with a specialist.
Schedule a consultation with an anti-age doctor at Sandler Wellness Center at 23 Kniaziv Ostrozky St, Kyiv, or through the website sandler.com.ua. Your brain deserves the same level of attention as any other organ.
