Synthetic regulatory heptapeptide
Selank
A synthetic peptide related to tuftsin, promoted online for anxiety, stress and cognitive effects despite a limited and hard-to-generalise evidence base.
Research interest
Stress and anxiety biology, neuroimmune signalling and cognitive measures in a small literature.
Evidence lens
Known does not mean proven for everything.
The strongest claim on the page should never be stronger than the strongest source behind it.
- Some human research has been reported, but the evidence base is not comparable with a modern approval dossier.
- FDA lists selank acetate among substances with important safety-information gaps.
- Online claims commonly outrun the available controlled evidence.
- Reliable effect size from large independent trials.
- Long-term safety, interactions and withdrawal effects.
- Quality of non-regulated nasal or injectable products.
- FDA highlights possible immunogenicity from aggregation and peptide impurities.
- Proposed human routes lack an adequate modern safety dataset.
- Neuropsychiatric symptoms deserve proper clinical assessment rather than self-experimentation.
Regulatory snapshot
Jurisdiction and context matter.
Not presented as a UK-authorised medicine. Verify current status through MHRA.
Not FDA approved; FDA reports important safety-information gaps for compounded selank acetate.
Athletes should verify the current WADA list and exact product; absence of a named entry is not clearance.
