Compound research · 8 November 2026 · 3 min read · By [European Peptide Shop](https://europeanpeptideshop.com/about/) ### On this page ## What Selank is Selank is a synthetic heptapeptide with the sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro, about 751.9 Da. It is built on tuftsin, a four-residue fragment of immunoglobulin G (Thr-Lys-Pro-Arg), extended at the C-terminus with Pro-Gly-Pro. Most of the published work comes from Russian research institutes. It is not a licensed medicine in the UK. ### Names and spellings "Selank" is the usual name. Older papers also call it TP-7 and describe it as a tuftsin analogue. It is a different molecule from tuftsin itself and from [Semax](https://europeanpeptideshop.com/blog/semax-research/). ### Supplied form Lyophilised powder in a 10mg single-compound vial, listed on the [Selank 10mg product page](https://europeanpeptideshop.com/shop/selank-10mg/). The Selank buying guide covers the catalogue side. ## Development and regulatory status Selank has no UK marketing authorisation, and the cited literature does not establish an FDA or EMA authorisation. The clinical literature is small and largely in Russian. Nothing on this page implies that Selank is licensed, prescribable or available for human use in the UK. ### Animal findings Published studies are in rats and mice. Examples: - A rat model of morphine withdrawal (2022). - A rat model of ethanol-induced memory impairment, with brain-derived neurotrophic factor measured in brain tissue (2019). - Rat studies of anxiety-related behaviour using TP-7, the older name (2006). ### Gene-expression findings Studies in mouse spleen and rat hippocampus report changes in the expression of immune-related and membrane-protein genes after Selank. These are mRNA measurements in animal tissue. On their own they say nothing about function in people. ### Human data One randomised comparison in 62 patients with generalised anxiety disorder and neurasthenia, comparing Selank with medazepam, was published in Russian in 2008. It is small, used an active comparator rather than placebo, and the cited record does not establish independent replication. It concerns a clinical product in diagnosed patients and cannot be transferred to a research reagent. ## What Selank is often confused with Compound | Parent | Sequence Selank | Tuftsin | Thr-Lys-Pro-Arg-Pro-Gly-Pro Tuftsin | Immunoglobulin G heavy chain | Thr-Lys-Pro-Arg Semax | ACTH(4-10) | Met-Glu-His-Phe-Pro-Gly-Pro Selank and Semax share a Pro-Gly-Pro extension at the C-terminus, which is why they are listed together. They come from different parent peptides and are not interchangeable. [Semax and Selank](https://europeanpeptideshop.com/blog/semax-vs-selank/) are compared on their own page, and the [Semax research overview](https://europeanpeptideshop.com/blog/semax-research/) covers the other compound. The rest of this group is in the nootropic category. ## Analytical documentation A certificate reports identity and measured purity for the batch tested. It says nothing about biological effect and does not extend to other batches. The guides to [reading a peptide COA](https://europeanpeptideshop.com/blog/how-to-read-peptide-coa/) and [understanding HPLC purity](https://europeanpeptideshop.com/blog/what-hplc-purity-means/) explain the limits. ## EPS documentation Use the [research catalogue](https://europeanpeptideshop.com/shop/) to check the exact name, labelled amount and format. The [COA library](https://europeanpeptideshop.com/coa/) publishes the original Janoshik reports selected for EPS, retaining the original report client name and any missing batch fields. Literature findings and another supplier's analytical results are not evidence about an EPS batch. ## Laboratory research only Materials listed on this site are supplied for in-vitro laboratory research and are not for use in or on humans or animals. They are not medicines. This article summarises published work and gives no dosing, administration, treatment or in-vivo guidance. Findings from a study apply to the material and conditions of that study, and they say nothing about any product listed here. ## References - [Kolik LG, Nadorova AV, Antipova TA, et al.
