Selank

A synthetic heptapeptide: the tetrapeptide tuftsin, Thr-Lys-Pro-Arg, extended at the C-terminus with Pro-Gly-Pro — the same stabilising extension used in semax, on a different parent sequence. Tuftsin is a fragment of the immunoglobulin G heavy chain. No receptor target for selank has been established in the published literature.

No registered human study names Selank as an intervention. ClinicalTrials.gov holds no trial of it, so there is no trial evidence to read — a fact about the public record rather than proof the compound does nothing. No FDA-approved product contains Selank. 19 papers naming it were published in the last ten years.

Collected 2026-08-02 from ClinicalTrials.gov and Drugs@FDA. Counts include only trials whose registered intervention names Selank; the registry search is fuzzy, so every match is re-checked. None of this says whether Selank works or is safe.

2 loose registry matches were checked and 0 confirmed — 2 named something else and were discarded. We count a study only when Selank is named as an intervention in it.

No study of Selank in humans is registered on ClinicalTrials.gov. That is a fact about the public record, not a statement that the compound does nothing — but it does mean there is no trial evidence to read, and anyone telling you otherwise should be asked for the registration number. The grade is mechanical: it is computed from the registry and the FDA record alone, and it grades how much is known, never whether a compound is good or safe.

What Selank is, and what it has been studied for

Selank is tracked here. Its FDA substance identifier is TS9JR8EP1G.

No registered trial names Selank as an intervention, so there is no condition it has been formally studied in. It does have a literature: 19 indexed papers name it in the last ten years. That work is laboratory and animal research, and a paper is not a trial.

Is anyone studying Selank?

Papers published each year that name Selank in the title or abstract, with the clinical trials that started in the same year marked beneath. Ten calendar years.

19 papers between 2017 and 2026. A paper counts when “Selank” appears in its title or abstract — phrase-matched, so a paper mentioning the words separately is not counted. The total is a single query over the whole window, which is why it does not equal the bars added together: PubMed files a paper under both its electronic and its print publication date, so one paper can appear in two years. Publication volume measures scientific attention, not whether a compound works: a well-studied compound can be well-studied and ineffective. Sources: PubMed and ClinicalTrials.gov · collected 2026-08-02.
