Mechanism of Action
Selank modulates GABA-A receptor expression, increases BDNF levels, and stabilizes enkephalin degradation. It influences serotonergic and noradrenergic signaling, producing anxiolytic effects without the sedation or tolerance associated with classical GABAergic compounds.
Storage & Handling
Store lyophilized at -20°C or 2-8°C. Reconstituted solutions at 2-8°C.

FAQ
Frequently Asked Questions
What is the relationship between selank and tuftsin?
Selank is a synthetic analog of tuftsin (Thr-Lys-Pro-Arg) with an added Pro-Gly-Pro C-terminal sequence for enhanced stability. Tuftsin is a naturally occurring immunomodulatory peptide derived from IgG.
How does selank compare to semax?
Both are synthetic peptides developed for nootropic research. Selank is primarily anxiolytic via GABA modulation, while semax is primarily neurotrophic via BDNF upregulation. They target different but complementary pathways.
How should selank be stored?
Store lyophilized selank at -20°C for long-term or 2-8°C for short-term storage. Reconstituted peptide should be refrigerated at 2-8°C and used within 30 days.
