How should Selank be stored?

In lyophilized powder form, Selank is stable at room temperature short-term but should be refrigerated (2–8°C) for longer storage and kept away from light and moisture. Once reconstituted, keep refrigerated and use within 30 days. Avoid freeze-thaw cycles.

Is Selank approved by the FDA?

No. Selank is not FDA-approved for human use in the United States, though it is approved as a pharmaceutical in Russia for anxiety-related research and treatment. NextSelf Labs sells Selank strictly as a research chemical for laboratory research.

What is the purity of your Selank?

All NextSelf Labs Selank is manufactured to ≥99% purity and verified by third-party laboratories using HPLC and mass spectrometry. The Certificate of Analysis for every batch is available on this page — match the batch number on your vial to the COA header to verify.

What makes Selank different from benzodiazepine-class research compounds?

Selank research has reported anxiolytic effects without the sedation, cognitive impairment, or dependence potential associated with benzodiazepine-class compounds, largely attributed to its action on GABA and serotonergic systems rather than direct GABA-A receptor binding.

Is Selank related to tuftsin?

Yes. Selank is a synthetic analog of tuftsin, an endogenous immunomodulatory peptide, with an added stabilizing sequence that extends its resistance to enzymatic degradation.

Do I need a prescription to purchase Selank?

No. NextSelf Labs sells Selank as a research chemical for laboratory use only.

About the Peptide

Calm, without the trade-offs.

Selank is a synthetic heptapeptide developed in the 1990s by researchers at Russia’s Institute of Molecular Genetics, built from the endogenous immunomodulatory peptide tuftsin with an added stabilizing sequence to resist enzymatic breakdown. It has since been approved as a pharmaceutical in Russia and studied extensively in the anxiolytic and nootropic research literature.

Modern stress rarely announces itself — it shows up as a racing mind at bedtime, a shortened fuse, a body that stays braced even when nothing is technically wrong. Selank research has focused on calming that response without the fog or dependence risk associated with more familiar anti-anxiety compounds.

Published research has documented Selank’s role in modulating GABAergic and serotonergic activity, upregulating brain-derived neurotrophic factor (BDNF) expression, and supporting balanced cytokine and immune signaling as a tuftsin-derived compound. It is among the more thoroughly characterized anxiolytic peptides in the Russian pharmacological literature.

Research Applications

Stress research, rethought.

Anxiolytic research has long carried a cost — sedation, dependence, cognitive fog. Selank represents a different approach, one increasingly relevant to how women researchers think about stress.

Anxiolytic Research Without Sedation

Selank has been studied for anxiolytic effects that do not carry the sedation, cognitive impairment, or dependence risk associated with benzodiazepine research.

BDNF & Neurotrophic Support

Research has documented Selank’s role in upregulating brain-derived neurotrophic factor (BDNF), a protein central to neuronal growth and plasticity research.

Immune Modulation

As a tuftsin analog, Selank has been studied for modulating cytokine expression and supporting balanced immune system function.
