What is Selank?

Selank extends the four-residue tuftsin sequence (Thr-Lys-Pro-Arg) with a stabilizing Pro-Gly-Pro tail, a modification designed to resist rapid enzymatic breakdown and extend its activity relative to native tuftsin. It was developed within a research program studying peptide-based approaches to anxiety and immune modulation.

This listing is Selank from Cyprus Peptides (Cyprus), sold on Stairway to Gray with escrow: your payment is held until the order arrives and only then released to the brand.

How it is understood to work

Selank is studied for effects on GABAergic signaling and monoamine neurotransmitter balance, along with reported influences on brain-derived neurotrophic factor (BDNF) expression and cytokine profiles. Its proposed anxiolytic activity is described as distinct from benzodiazepine GABA-A receptor mechanisms, which researchers cite as a possible explanation for its reported lack of sedative effect in study models.

Research status

Selank has been investigated in behavioral neuroscience research on anxiety and stress response, in memory and learning models, and in immunology research given its tuftsin lineage. Much of the primary literature originates from a limited number of research groups and has not been replicated at the scale seen for established anxiolytics, so its pharmacology should be regarded as an active but still-developing area of study.

Questions

How is Selank related to tuftsin?

Selank incorporates the native tuftsin sequence (Thr-Lys-Pro-Arg) but adds a Pro-Gly-Pro tail intended to slow enzymatic degradation, giving it a longer window of activity than tuftsin itself in study models.

Why are 5mg, 10mg, and 11mg pack sizes all listed?

Each contains the same Selank peptide and purity specification; the differing totals reflect different manufacturer fill sizes rather than any difference in the compound itself.
