02Mechanism of Action
Selank is a synthetic heptapeptide derived from the immunomodulatory peptide tuftsin. Research focuses on its modulation of GABAergic neurotransmission and influence on BDNF expression, studied in anxiety and stress behavioral models.
It is also reported to inhibit enkephalin-degrading enzymes and to modulate cytokines such as IL-6 in immunological assays — all within research contexts.

05FAQ
What is Selank?
Selank is a synthetic analog of the peptide tuftsin, studied for GABAergic modulation, anxiolytic signaling, and BDNF expression in research models. It is sold for research use only.
What is Selank's sequence?
Selank has the sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro and a molecular weight of approximately 751.88 g/mol.
What is the CAS number of Selank?
Selank has CAS number 129954-34-3.
How should Selank be stored?
Selank ships lyophilized and should be handled per standard research-peptide practice — kept cold, protected from light and moisture, and reconstituted only for laboratory use. Cold-chain handling is used where required. For research use only.
Is Selank approved for human use?
No. Selank is sold strictly for laboratory research use only and is not a drug or supplement. It is not approved for human or veterinary use or consumption.
How is Selank tested at Ethos Bio?
Every Selank lot is independently verified by MZ Biolabs, a third-party analytical laboratory in Arizona, on a five-point panel — RP-HPLC purity, HPLC-MS identity, endotoxin (LAL), heavy metals, and sterility. A lot-specific certificate of analysis ships with the vial. See How We Test for the full methodology.
