Why does the vial look empty?

That’s normal. The peptide is supplied lyophilised (freeze-dried) — often a thin film or a few milligrams at the base of the vial, easy to mistake for empty. It’s all there; reconstitute with bacteriostatic water before use.

Research handling note

Reconstitute with bacteriostatic water and store the lyophilised vial at −20 °C until use; once reconstituted, refrigerate and use within the documented window. For laboratory research purposes only — not for human consumption, diagnostic, or therapeutic use. Need to work out your dilution? Use the reconstitution calculator →

Neuropeptide Research

Selank — research profile

For research purposes only — not for human consumption

Selank is a synthetic analogue of the endogenous tetrapeptide tuftsin, developed at the Institute of Molecular Genetics in Russia. It is studied for calm-focus, anxiolytic-like and immunomodulatory activity without the sedation associated with classical anxiolytics.

Research models report effects on the balance of monoamine and GABAergic signalling, on brain-derived neurotrophic factor (BDNF) expression, and on the stability of endogenous enkephalins via inhibition of their degrading enzymes.

How it’s studied

Anxiolytic pathways: GABA-A and serotonergic balance in behavioural models.
Enkephalinase inhibition: stabilisation of endogenous regulatory peptides.
BDNF expression: neurotrophic signalling in the hippocampus.
Immunomodulation: tuftsin-linked immune signalling.

Areas under investigation

Stress response	Anxiolytic-like activity without sedation in models.
Cognition	Attention and memory pathways in research cohorts.

Verifiability

Batch Testing & COA

Every production batch is sent for independent, third-party analysis at Janoshik Analytical. When results return, the full Certificate of Analysis for the exact batch you receive is published here and in our COA library, carrying its SHA-256 checksum and the lot number printed on your vial, so you can confirm the document is genuine and untampered. We publish every certificate, including any that fail.
