Selank 10mg research vial
Selank is a lab-made 7 amino acid peptide based on tuftsin; one 10mg vial costs 3,800,000 VND ($150 USD). Selank's four studies open on PubMed from this page, and we last confirmed its price on 11 October 2026.
What is Selank?
Tuftsin is a small natural peptide linked to the immune system. Selank is tuftsin with 3 amino acids added, and its sequence is Thr-Lys-Pro-Arg-Pro-Gly-Pro.
Like Semax, it comes mostly out of research groups in Moscow, and several papers are in Russian.
Good to know
Selank and Semax come from the same Moscow labs, so they often get mentioned together. They start from different places. Selank starts from tuftsin, and Semax from a piece of ACTH.
Selank in Moscow research, 2008 to 2020
- Human trial, 2008. A Russian study of 62 people with anxiety set Selank against an older drug, medazepam, and tracked anxiety scores.
- Animal study, 2016. In rats, the study measured the activity of dozens of genes linked to GABA, the brain's main calming signal.
- Cell study, 2018. Lab work looked at how strongly GABA binds to brain cell membranes when Selank is present.
- Brain scan trial, 2020. The same 52 adult brain scan study listed on the Semax page put Selank, Semax and a placebo side by side.
Mostly rat and lab research plus a few small human studies, nearly all from Russian teams.
How to read this
The main human Selank study is one 2008 Russian study of 62 people with anxiety, set against an older drug. The rat and cell studies point to GABA, the brain's calming signal, as the system being studied. The 2020 brain scan study tested each one on its own, so it tells you about each one, not about using both.
The Selank paper trail
The 2008 study set Selank against medazepam, an older drug, and ran in a Russian neurology journal. The rat gene study came out in 2016, the lab study in 2018 and the brain scan study in 2020. Most of this work comes from groups in Moscow, and several papers are in Russian. The sequence starts with Thr-Lys-Pro-Arg, the four amino acids of tuftsin.

Questions about Selank
What has research on Selank looked at?
Anxiety scores in one Russian human study. GABA signalling in rats and cells. A brain scan comparison.
How is Selank related to tuftsin?
Selank is tuftsin with 3 more amino acids added to the end. Tuftsin is a small natural peptide tied to the immune system, and its four amino acids fill the first four places of Selank. The full Selank sequence is Thr-Lys-Pro-Arg-Pro-Gly-Pro.
Does Selank end the same way as Semax?
Yes. Both end in Pro-Gly-Pro, the three amino acids added to each base peptide: tuftsin for Selank, and a piece of ACTH for Semax.
