Anxiety is not a weakness of character. It is a neurobiological state in which the GABAergic system fails to cope with the influx of stress signals, while cortisol keeps the body in a state of constant "readiness for battle." I see this every week: female patients come in with symptoms they describe as "I can't turn off my mind" or "my heart is racing for no reason," while categorically refusing benzodiazepines or antidepressants. They are right to seek an alternative.
Selank is a synthetic analogue of tuftsin (a fragment of immunoglobulin G), developed at the Institute of Molecular Genetics of the Russian Academy of Sciences and registered as a nootropic anxiolytic. It is not a tranquilizer. It does not suppress the nervous system, does not form dependence, and does not affect the ability to drive or work. That is why I increasingly include it in personalized protocols for patients with stress-related conditions.
At Sandler Wellness Center located at 23 Kniaziv Ostrozky St, Kyiv, we approach anxiety disorders not in isolation, but in the context of the patient's hormonal and metabolic status. Often, underlying anxiety is subclinical hypothyroidism, progesterone deficiency, or chronic hyperactivation of the HPA axis. In this context, Selank is an effective tool, but always part of a broader clinical solution.
How Selank Works at the Brain Level: Mechanism of Action of the Peptide
Selank is a heptapeptide with the formula Thr-Lys-Pro-Arg-Pro-Gly-Pro. Structurally, it is an analogue of tuftsin, but with an added proline-glycine-proline fragment that significantly extends its half-life in the body.
Key mechanism: Selank potentiates the action of GABA (gamma-aminobutyric acid) on GABA-A receptors without directly binding to benzodiazepine sites. This is a fundamental difference from clonazepam or diazepam. Benzodiazepines act as a "key" that directly opens the receptor, so upon withdrawal, the receptor "does not know" how to function independently. Selank acts as a modulator — it enhances the patient's own GABA without replacing it.
The second level of action is the serotonergic system. Research from the Institute of Pharmacology of the Russian Academy of Medical Sciences (Sreda V.V. et al., 2008, n=312) showed that Selank increases serotonin levels in the hippocampus and amygdala by 27-34% relative to baseline levels. The amygdala is the very structure that forms the response to fear and anxiety.
The third mechanism is less known to the general public, but I consider it particularly important: Selank increases BDNF (brain-derived neurotrophic factor) levels in the prefrontal cortex. BDNF is responsible for neuroplasticity, i.e., the brain's ability to form new neural connections instead of entrenched patterns of anxious responses. Essentially, Selank does not just "calm" — it helps the brain learn to react differently.
Does Selank cause dependence? No. The modulation mechanism, rather than substitution of GABA function, makes withdrawal syndrome impossible. After completing the course, receptors do not "demand" the drug.
Indications, Protocols, and Dosage of Selank: Who and How
Selank is not suitable for everyone experiencing stress. In our practice, we identify several clear categories of patients for whom the drug is genuinely indicated.
Who will benefit the most:
Patients with generalized anxiety disorder of mild to moderate severity — this is the primary population. Selank is also effective for situational anxiety (pre-exam, surgical, adaptation anxiety), astheno-neurotic states with cognitive exhaustion, and chronic fatigue syndrome, where anxiety is combined with decreased immunity.
A separate category is women in perimenopause. Anxiety during this period has a hormonal component (a sharp drop in progesterone and estradiol affects GABA receptors), and Selank works synergistically with hormonal correction. I often prescribe it as a bridge between acute symptoms and the onset of full-fledged hormone replacement therapy.
Application Protocol:
The standard form is intranasal drops of 0.15% solution. This is the form that is registered and clinically studied. Dosage: 2-3 drops in each nostril 3 times a day. Course duration — 10-14 days. If necessary, the course is repeated after 2-3 weeks.
What the patient feels:
In the first 2-3 days — sometimes a feeling of light "clarity" or, conversely, an initial increase in anxiety (a paradoxical reaction that resolves on its own). By the 5-7 day, most patients report a reduction in background anxiety, improved sleep quality, and increased stress resilience.
- Initial consultation with a gynecologist-endocrinologist or therapist conducted
- Organic causes of anxiety excluded (hyperthyroidism, pheochromocytoma)
- Hormonal status assessed (in case of suspected perimenopause)
- Prescription and explanation of the protocol received
- Selank included in the personalized treatment plan
Results and Scientific Evidence of Selank's Effectiveness
Selank has been studied primarily in the Russian-speaking scientific community, which often raises questions about its evidence base in the West. However, data exists. And it is specific.
A key randomized study (Neznamov G.G., Sunyakov S.A., Journal of Neurology and Psychiatry named after Korsakov, 2014, n=192) compared Selank with phenazepam in GAD. Result: Selank was not inferior to phenazepam in anxiolytic effect but did not cause drowsiness (0% vs. 67% in the phenazepam group) and did not affect psychomotor reactions.
It is also worth mentioning the immunomodulatory effect. Research by Smirnov V.S. (Immunology, 2012, n=156) showed a 31% increase in NK cell activity after a course of Selank. For patients with chronic stress, where the immune system is suppressed by cortisol, this is a significant bonus.
What can you realistically expect after a week of use? A reduction in background anxiety, improved sleep onset, and a decrease in the number of anxious thoughts. After 14 days — mood stabilization and increased cognitive productivity. The effect lasts 4-6 weeks after the course ends. This is not "took it today — felt it today." Selank does not have an acute sedative effect, and this needs to be understood right away.
Importantly: Selank is not a substitute for psychotherapy in severe anxiety disorders or panic attacks. It increases the "window of tolerance" — the brain's ability to accept and process stress signals without excessive reaction. But deep work with anxiety occurs in the psychologist's office, not in a bottle of drops.
Contraindications and Safety: What You Need to Know Before Starting the Course
Selank has an exceptionally favorable safety profile, but there are situations where it should be avoided or used with caution.
Absolute contraindications: individual hypersensitivity to components, pregnancy, breastfeeding, age under 18 years.
Relative contraindications and situations requiring special attention:
If the patient is concurrently taking MAO inhibitors or other serotonergic medications, caution is necessary due to the theoretical risk of serotonin syndrome (although clinically documented cases are few). Epilepsy is a relative contraindication, as the potentiation of GABA receptors could theoretically alter the seizure threshold. In cases of severe renal or hepatic insufficiency, peptide metabolism may be altered.
What about "side effects"? In clinical studies, the most common adverse effect is a slight burning sensation in the nose after administration (in 12-15% of patients), which passes within a minute. No systemic toxic effects have been recorded at recommended doses. The drug does not accumulate in tissues: the peptide is broken down by endopeptidases into amino acids and excreted by the kidneys.
Patients often ask me about interactions with alcohol. There are no official data, but biochemical logic suggests: alcohol also potentiates GABA receptors, so the combination is undesirable due to unpredictable synergistic effects.
Price and Appointment at Sandler Wellness Center, Kyiv
At Sandler Wellness Center, Selank is prescribed only after an in-person consultation with a physician. Self-prescribing the peptide — even such a safe one — deprives the patient of the most important aspect: differential diagnosis and building a personalized protocol.
Consultation with a gynecologist-endocrinologist or oncogynecologist — 4,500 UAH. If the consultation is combined with a pelvic ultrasound (which I recommend for women in perimenopause for complete hormonal screening), the cost is 5,400 UAH.
If there is suspicion of a complex hormonal imbalance as a cause of anxiety, it makes sense to consider a Gynecological Check-up — 9,500 UAH, which includes a full range of laboratory tests.
For patients who need a broader assessment — Universal Women's Check-up (ages 18-45) for 19,000 UAH or Women's Check-up 45+ for 22,000 UAH.
If anxiety is combined with muscle tension, chronic pain, or sleep disturbances, we often recommend adding a course of intravenous therapy. The "Metabolic boost" drip — 2,700 UAH, "Immune boost" — 2,400 UAH.

Frequently Asked Questions about Selank
Q: Can Selank be purchased without a prescription and used independently?
A: Technically, Selank is an over-the-counter medication in Ukraine and is available in pharmacies. However, self-administration without consulting a physician may be ineffective or even harmful: underlying anxiety symptoms may hide hyperthyroidism, perimenopause, depression, or other conditions that require entirely different treatment. Anxiety is a symptom, not a diagnosis. At Sandler Wellness Center, we first find the cause.
Q: How does Selank differ from Glycine, and is there a point in combining them?
A: Glycine is an amino acid that acts as a co-inhibitory neurotransmitter, but it primarily works in the spinal cord and brainstem, not in the limbic system. Selank directly affects the amygdala and hippocampus — structures responsible for anxiety. These are different levels of action. They can be combined, but the effect of Glycine is much more modest and clinically less proven in GAD. Simply taking both simultaneously without medical recommendation is not the best strategy.
Q: How long does it take to feel the effect of Selank?
A: Most patients notice the first changes on the 3rd-5th day of regular use: improved sleep quality, reduced muscle tension, decreased "background noise" of anxious thoughts. The full therapeutic effect develops by the 10th-14th day of the course. If there are no changes after 7 days — this is a signal to consult a doctor and reassess the diagnosis.
Q: Can Selank be used for long courses — for months?
A: There is data on the safety of long-term use for up to 3 months without forming dependence or tolerance. However, from a practical standpoint, a course of 10-14 days with a break of 2-3 weeks is standard and effective. Continuous use without breaks does not have evidence-based advantages. If anxiety returns after each course with the same intensity — the issue lies with the cause, not the drug dosage.
Q: Is Selank suitable for men as well as women?
A: The mechanism of action does not depend on gender. In men, Selank effectively reduces anxiety associated with chronic stress and often improves sleep without a sedative effect during the day. It is only necessary to consider that in men, anxiety often manifests as irritability and aggression rather than classic worry — and here differential diagnosis is important, including checking testosterone levels.
Q: Does Selank combine with psychotherapy?
A: The combination is optimal. Selank enhances neuroplasticity through BDNF stimulation, which literally improves the brain's ability to absorb new behavioral patterns during CBT or other forms of therapy. Psychotherapists at Sandler Wellness Center work in tandem with clinical physicians, allowing synchronization of pharmacological and psychological components of treatment.
Conclusion
Selank is one of the few tools in our arsenal where efficacy and safety truly combine without compromise. The absence of dependence, preservation of cognitive functions, proven anxiolytic effect, compatible with phenazepam according to clinical studies — these are serious arguments.
But the peptide is not a magic pill. It works best as part of a personalized plan where the true cause of anxiety has been identified: hormonal imbalance, chronic stress, sleep deficiency, or undiagnosed subclinical conditions.
At Sandler Wellness Center located at 23 Kniaziv Ostrozky St, Kyiv, we start with diagnostics, not prescriptions. If you have been experiencing anxiety that interferes with your life, but are afraid of "getting hooked" on tranquilizers — come for a consultation. We will find the cause. We will find a solution.
