Product Overview
Selank 10 mg by Peptide Hubs
Selank 10 mg is a lyophilized powder peptide manufactured by Peptide Hubs containing Selank at 10 mg per vial, supplied in a 2 mL vial.
Selank Injectable
Selank is a synthetic heptapeptide with the sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro. It is an analog of tuftsin, a naturally occurring immunomodulatory peptide fragment. Research on Selank has focused primarily on its potential anxiolytic and nootropic properties, with proposed mechanisms involving modulation of GABAergic signaling and inhibition of enkephalin-degrading enzymes.
In Russia, a 0.15% intranasal formulation of Selank has been registered for medical use as an anxiolytic. International regulatory agencies, including the FDA, have not approved Selank for any indication. Studies examining Selank's effects have been limited in scope, with small sample sizes and short durations. In non-medical contexts, Selank is sometimes referenced for anxiety management and cognitive support, though such use falls outside any approved indication.
The peptide is supplied as a lyophilized powder, a format that supports stability before reconstitution. Research on Selank's mechanisms has explored its interactions with neurotransmitter systems and its potential influence on neurotrophic factor expression. However, the evidence base remains preliminary, and clinical data from well-controlled international trials are lacking.

Product Profile
Selank Profile
Selank is a synthetic peptide developed from the tuftsin sequence, with research interests centered on neuropeptide signaling and potential anxiolytic activity. Its proposed mechanisms distinguish it from conventional anxiolytic medications.
Tuftsin Analog Heptapeptide
Selank (Thr-Lys-Pro-Arg-Pro-Gly-Pro) is a synthetic analog of tuftsin, a tetrapeptide fragment of immunoglobulin G. The addition of a Pro-Gly-Pro tripeptide to the tuftsin sequence is designed to enhance stability and prolong activity. Research has explored Selank's interaction with GABA receptors, with evidence suggesting it acts as a positive allosteric modulator.
Another proposed mechanism involves inhibition of enkephalin-degrading enzymes, potentially increasing endogenous enkephalin levels and influencing opioid receptor signaling. These pathways are associated with mood, stress response, and pain regulation. Selank has also been studied for effects on neurotrophic factor expression in the hippocampus.
Unlike benzodiazepines, Selank is not reported to cause sedation, dependence, or withdrawal symptoms in Russian clinical literature, though independent international data are limited.
Defining Characteristic
Neuropeptide Modulation Without Sedation
Selank's distinguishing feature in research contexts is its proposed mechanism of modulating endogenous neuropeptide systems rather than directly activating GABA receptors like benzodiazepines. This mechanism is hypothesized to produce anxiolytic effects without the sedation and dependence associated with conventional anxiolytics.
Selank 10 mg vs Other Peptide Hubs Preparations
Peptide Hubs offers a range of research peptides targeting different physiological systems. Selank's focus on neuropeptide signaling and potential anxiolytic activity distinguishes it from compounds that act on growth hormone pathways, such as Ipamorelin or CJC-1295 No DAC. For cognitive and neurological research, Semax is a related synthetic peptide studied for nootropic effects through different proposed mechanisms.
Other Peptide Hubs products address tissue repair, such as BPC 157 and TB 500, or sleep regulation, such as DSIP. These compounds operate through pathways unrelated to Selank's proposed neuropeptide modulation.

Dosage & Usage
Selank 10 mg Dosage & Usage
The information below is provided for educational reference only. Selank is not approved by the FDA for any indication. Medical use in Russia requires prescription and supervision. Non-medical use falls outside approved indications.
Typical Dosage Ranges
The registered Russian protocol for Selank specifies 300 mcg per dose, administered intranasally three times daily for a total of 900 mcg per day, in courses of 10 to 14 days. In non-medical research contexts, subcutaneous administration is sometimes referenced at 250 to 500 mcg per injection, once or twice daily, though this route has no clinical precedent in human studies.
| Use Case | Common Reference Range | Frequency |
|---|---|---|
| Registered Russian protocol (intranasal) | 300 mcg per dose | Three times daily, 10–14 day course |
| Non-medical (subcutaneous reference) | 250–500 mcg per injection | Once or twice daily |
Stacking & Cycle Considerations
No established stacking protocols exist for Selank in clinical literature. In research contexts, Selank is studied as a standalone intervention. The Russian label recommends courses of 10 to 14 days with breaks of 2 to 4 months between cycles, though longer or continuous use is sometimes referenced in non-medical communities without clinical evidence.
Reconstitution should be performed with Bacteriostatic Water following standard sterile technique. There is no loading phase established for this peptide.
Managing Side Effects
Common adverse effects reported in Russian clinical literature include nasal mucosa irritation (for intranasal use) and rare allergic reactions. Independent international data on safety are lacking, and long-term effects of non-medical use are not characterized.

Individual Response Varies
Dosing strategies should be considered in the context of individual factors. The information above is for educational reference and does not constitute medical advice.
Safety & Information
Selank Safety Information
Selank is not FDA-approved for any indication. Safety data come primarily from Russian clinical literature, and international regulatory assessments are limited.
Important Safety Information
Selank is registered in Russia as a prescription anxiolytic for intranasal use. It is not approved by the FDA, EMA, or other major international regulatory agencies. The evidence base for its efficacy consists of small, predominantly Russian studies with limited independent replication.
No well-controlled international clinical trials have established the safety or efficacy of Selank outside of Russian clinical practice.
Important
Non-Medical Use
Selank is not approved for human use in the United States. Non-medical use is not supported by safety data and occurs without the monitoring present in clinical settings.
Potential Adverse Effects
Russian clinical literature reports nasal mucosa irritation as a common effect with intranasal use. Allergic reactions are listed as rare. Independent data on serious adverse events are unavailable.
Because clinical trials have been small and short-term, long-term side effects and any potential for dependence or withdrawal have not been established. Unlike benzodiazepines, Selank has not been associated with sedation or rebound anxiety in Russian post-marketing reports.
Conditions Requiring Medical Evaluation
Per Russian labeling, Selank is contraindicated in pregnancy, breastfeeding, individuals under 18 years of age, and those with hypersensitivity to the peptide. These contraindications reflect the limited safety data rather than identified severe risks.
Monitoring During Therapy
No specific monitoring protocols exist for Selank outside Russian clinical practice. The lack of international regulatory approval means no standardized safety monitoring guidelines are available.
