Selank is a synthetic tuftsin-derived heptapeptide studied in Russian clinical anxiety research and in rodent/cell models of GABAergic gene expression.
In patients with generalized anxiety disorder and neurasthenia, selank produced anxiolytic scale-score changes comparable to medazepam with additional antiasthenic score shifts.
In rat frontal cortex, selank altered expression of multiple genes involved in GABAergic neurotransmission in a pattern correlating with GABA administration.
In IMR-32 neuroblastoma cells, selank modified GABA-linked gene-expression responses in co-application experiments on a GABAergic pathway panel.
These summaries describe findings reported in published laboratory and clinical literature about this compound. They are provided for research context only. They are not claims about this product, and nothing here describes an intended use in humans or animals. This material is supplied strictly for laboratory research use.
This listing supplies the compound as a pre-mixed nasal spray rather than a lyophilized vial, so no reconstitution step is required before use in a laboratory workflow. Intranasal delivery is studied as a non-injectable route that avoids first-pass hepatic metabolism; the published literature summarised below was generated across a range of administration routes, and route is one of the variables recorded in the reported-amounts table. Comparisons between routes are not equivalence claims — absorption differs by formulation and is documented per product, not inferred.
Because this nasal spray is supplied pre-prepared, the reconstitution arithmetic that applies to our lyophilized Selank vials does not apply here: there is no diluent volume to choose and no concentration to derive. Store as labelled on the product, and consult the lot-matched Certificate of Analysis for the material you receive rather than generalising from a different format of the same compound.
synthetic heptapeptide anxiolytic research compound
Selank is a synthetic heptapeptide derived from the immunomodulatory tetrapeptide tuftsin, extended with a Pro-Gly-Pro sequence. Research has examined anxiolytic-like behavior, cognitive endpoints, cytokine signaling, monoamine systems, and gene-expression changes related to GABAergic neurotransmission. Much of the literature comes from Russian research groups and includes both clinical and preclinical designs.
Education content should keep Selank in research-use framing. It is not an FDA-approved drug product, and research-grade Selank is Research Use Only and not for human consumption. Reported ranges below reflect published human or animal study contexts where available and should not be treated as a protocol.
Selank is studied as a tuftsin analog with neuroimmune and neuromodulatory effects. Published work links it to GABAergic gene-expression changes, monoamine metabolism, cytokine modulation, and anxiolytic-like behavioral outcomes. Unlike a single-receptor sedative model, Selank appears in the literature as a multi-pathway peptide with immune and CNS dimensions. That makes endpoint selection and comparator choice important in research design.
Fields of active investigation, not claims. Investigation is not proof.
Selank is studied by neuropharmacologists, behavioral neuroscience groups, psychopharmacology researchers, and immunology-focused peptide labs. Translational reviewers pay close attention to country of origin, formulation, route, and trial design.
What published research and laboratory protocols document. These describe what was studied — they are not instructions, recommendations, or a protocol for use.
| Reported amount | Frequency | Route | Research context |
|---|---|---|---|
| 900 mcg – 2.7 mg | daily in study protocols | intranasal | Clinical intranasal Selank literature commonly discusses sub-milligram to milligram daily exposure |
| 100 mcg – 300 mcg | daily course in animal protocols | intraperitoneal or intranasal in animal studies | Rat behavioral research with Selank |
Lyophilized Selank is commonly stored cold, dry, and protected from light; reconstituted research solutions are generally refrigerated and handled aseptically.
Selank is often discussed with Semax, nootropic compounds, or anxiolytic comparators, but combined CNS protocols can obscure whether changes reflect peptide effects, stress adaptation, or comparator pharmacology. Research designs should define behavioral endpoints and avoid converting regional clinical literature into general dosing advice.

what is the dosage for Selank
Published Selank discussions include intranasal human study contexts and animal mcg/kg work. These are reference values only, not recommendations.
how much bacteriostatic water for Selank
Small research vials are often modeled with 1-2 mL reconstitution volumes. The chosen volume sets concentration for lab calculations.
Selank dosage per day
Daily exposure in the literature depends on route, formulation, and study design. Research-grade Selank is not for human consumption.
Selank dosage chart
A responsible chart should separate human intranasal study references from animal per-kg experiments and clearly label all values as research context.
how long does Selank take
Behavioral and subjective endpoints in studies are usually assessed over days to weeks, while molecular endpoints can be measured on shorter timelines.
Selank half life
A practical human half-life is not well standardized in the mainstream literature. Effects may be discussed separately from simple plasma persistence.
can Selank be stacked
It can be studied with comparators such as anxiolytic drugs or other peptides, but stacking complicates attribution and is not a use recommendation.
