MOLECULE PROFILE

Selank

Peptide or peptide-related

Tuftsin analogue promoted for anxiety and stress adaptation. Nasal, injectable and chemically modified formulations must not be grouped as one intervention.

Sources checked · October 16, 2026

Published for review · Scientific, medical, translation and citation review pending. Reported uses are not authorized indications. Frequency reflects mentions in supplied sources, not sales or global clinical prevalence.

Identity and synonyms

Identity follows the supplied name and synonyms; no additional identity description is supplied.

Synonyms: TP-7 · Selank acetate

Peptide or peptide-related · Peptide or peptide derivative

Detailed molecular class: Synthetic peptide

Supplied sequence or chemical reference

See identity note; no supplier sequence accepted as verification.

Mechanism

Experimental anxiolytic and enkephalin-related effects.

Evidence and critical reading

Reported scientific and empirical uses

Cognition and neurology

Handbooks describe anxiolytic/nootropic uses and alternation with Semax. Claims of no dependence, tolerance or interactions require their own long-term evidence.

Human evidence

A 62-person comparator report does not establish equivalence to modern standard care or the Semax/Selank stack.

Preclinical evidence

Neurochemical findings are not proof of long-term anxiety control.

Critical reading and limitations

A study compared Selank with medazepam in 62 participants. Its abstract does not establish formal equivalence, sustained superiority or mixture safety. Nasal bottle concentration alone does not determine quantity per spray or drop.

Evidence applies to the exact molecule, formulation, route, population and endpoint studied. Supplier identity, purity and clinical equivalence are unverified.

Source-specific regimens

Descriptive source observations, not individual recommendations.

Regulatory product labeling

Listed regimens preserve source/context. An empty layer means no regimen attributable to this identity was verified in this review; it does not prove universal absence of data.

Human-study exposure

Listed regimens preserve source/context. An empty layer means no regimen attributable to this identity was verified in this review; it does not prove universal absence of data.

Empirical handbook

NOT A RECOMMENDATION.Each amount is attributed to the source identified for that entry: regulatory product labeling, human research, or community and practice sources. These source categories have different evidentiary roles. They are not medical advice, not a protocol, not a recommended or safe dose, and not evidence that it works. Do not use them to start, change or stop any treatment. Talk to a qualified healthcare professional.

Regulation and safety

Jurisdiction-specific regulatory context

Jurisdiction-specific approval not verified in this card; do not infer global nonapproval.

Adverse effects and unknowns

Long-term safety and interactions are incompletely characterized; acetylated/amidated analogues require separate evidence.

Contraindications

See supported safety statements and exact product label; a complete contraindication set has not been established for this catalog material.

A complete list must match the exact authorized product. For experimental materials without verified human labeling, a complete contraindication set is not established here. No list does not mean safety.

Interactions

Only explicitly cited interactions may be asserted; unstudied combinations remain unknown, not interaction-free.

Separate documented interaction, pharmacologic plausibility and unknown interaction. Absence of a blend trial does not establish compatibility.

Studies and trials

Selected studies

PMID18454096 · Small active-comparator study

Generalized anxiety/neurasthenia.

Route not verified in the selected abstract.

Anxiolytic effects described as similar to medazepam.

No formal equivalence or long-term safety demonstration.
