Selank is a synthetic heptapeptide with the amino-acid sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro. It was developed as an analog of the naturally occurring immunomodulatory peptide tuftsin and is investigated as a distinct research compound.
In controlled laboratory environments, Selank may be studied in connection with peptide signaling, gene-expression patterns, neurotransmitter-related pathways, cytokine activity, cellular stress responses, and experimental neurological or immunological models.
Full research description
Published studies have explored Selank in relation to GABAergic signaling, monoamine systems, enkephalin metabolism, cognition, behavioral stress responses, and immune-related processes. However, many reported findings come from animal studies, limited clinical investigations, or research conducted outside the United States. These findings do not establish safety, effectiveness, appropriate dosage, or suitability for administration to humans or animals.
Claims that Selank treats anxiety, depression, cognitive impairment, influenza, stress-related conditions, pain, or any other medical condition have been omitted because such statements could imply therapeutic or preventive use. References to cognitive enhancement, mental clarity, improved memory, mood regulation, or effects comparable to benzodiazepines have also been removed.
Selank is not an FDA-approved drug in the United States. FDA has stated that compounded products containing Selank acetate may present immunogenicity and peptide-impurity concerns and that it lacks sufficient safety information regarding administration to humans. FDA has also previously identified drug products compounded with Selank as ineligible for certain federal compounding exemptions.
The terms Selank, Selank acetate, and chemically modified forms such as N-acetyl Selank should not be treated as interchangeable. Sequence, salt form, terminal modifications, purity, identity, and molecular composition should be verified using batch-specific analytical documentation.
Storage & handling
Before reconstitution. Keep the sealed vial cool and dark. Lyophilized peptides are stable this way for the period stated on the certificate.
Reconstitution. Add bacteriostatic water slowly against the inside wall of the vial. Swirl gently to dissolve — never shake, as agitation can damage the peptide chain.
After reconstitution. Store refrigerated and use within the window appropriate for the compound under study. Do not freeze once in solution.
Check that the batch code on the label matches your packing slip on arrival.
COA & testing
Every batch is analysed by an independent laboratory before it is listed. The method for this compound is HPLC-UV 214nm.
The certificate shows the main peak purity, the impurity profile, the test date and the laboratory that performed it — tied to the batch code printed on your vial.
