Selank
In stockTP-7Heptapeptide Thr-Lys-Pro-Arg-Pro-Gly-Pro, built on the endogenous tetrapeptide tuftsin with a Pro-Gly-Pro extension. Researchers study it in rodent models and in analytical identification work.
Supplied as a single-chamber lyophilized vial with a colour-coded cap (Cognition & Focus).

Questions about Selank
How much published research is there on Selank?
The research library's PubMed search for Selank returned 126 records on 5 October 2026, 4 of them reviews. The library lists 4 studies chosen for what they measured. ClinicalTrials.gov lists 2 registered studies naming Selank, 1 of them sponsored by Bambino Gesù Hospital and Research Institute (checked 5 October 2026).
Is Selank an approved medicine?
No centrally authorised medicine containing Selank is listed in the EMA medicines database (checked 5 October 2026), and the research material we supply is not a medicine. It is supplied for in-vitro laboratory research only, not for human or veterinary use.
What is Selank built on?
On the endogenous tetrapeptide tuftsin (Thr-Lys-Pro-Arg), with a Pro-Gly-Pro extension.
How does Selank differ from Semax?
Semax and Selank are both heptapeptides ending in Pro-Gly-Pro. Semax is an analogue of ACTH(4-10) and Selank an analogue of the tetrapeptide tuftsin.
How is the identity of Selank confirmed on a certificate?
A research-grade certificate of analysis typically reports identity by mass spectrometry and purity by HPLC. The mass result is read against the average molecular weight of 751.9 Da listed on this page. The research library's guide to reading a certificate explains each field.
Is this product for human use?
No. Peptency products are supplied for in-vitro research only. Not for human or veterinary use, not for diagnosis or therapy.
Where can I find shipping information?

Published work includes rodent studies, one resting-state imaging study and one analytical identification. We supply Selank as a lyophilized vial for in-vitro laboratory research only.
What are the chemical identifiers of Selank?
Selank has the molecular formula C33H57N11O9, an average molecular weight of 751.9 Da and CAS number 129954-34-3.
Chemistry checked against PubChem (CID 11765600), 5 October 2026; full chemistry record in the research library.
What does published research on Selank cover?
A PubMed search for Selank returned 126 records on 5 October 2026, 4 of them reviews. Our research library lists 4 of these studies, chosen for what they measured.
- A rat study measured object-recognition memory and BDNF content in brain structures after long-term ethanol exposure. (Kolik et al., Bull Exp Biol Med, 2019; PMID 31625062)
- A rat study measured behaviour in a 6-OHDA model of parkinsonism after Semax and Selank. (Slominsky et al., Dokl Biol Sci, 2017; PMID 28702721)
Mechanism, every cited study and the regulator records are on the Selank page of the research library. Papers are listed by what they measured, not as evidence of any use.
How is Selank supplied and stored?
Selank is supplied as a lyophilized (freeze-dried) powder in a sealed vial, for in-vitro laboratory research only. Our stated storage condition for the sealed lyophilized vial is 2 to 8 °C. The label and the lot certificate carry the lot-specific storage condition and expiry date.
What is the regulatory status of Selank?
The EMA medicines database (checked 5 October 2026) lists no centrally authorised medicine naming Selank as an active substance. National authorisations are not in that dataset.
No SmPC, PIL or PAR document in MHRA Products matches the exact name (checked 5 October 2026).
A regulator record is information about a database entry. It is not advice and not a statement that any use is lawful or unlawful in any country. How regulators approach research peptides.
