Selank (Thr-Lys-Pro-Arg-Pro-Gly-Pro) is a synthetic heptapeptide built on tuftsin, the immunomodulatory tetrapeptide Thr-Lys-Pro-Arg released from the Fc region of immunoglobulin G, with a C-terminal Pro-Gly-Pro extension added to slow enzymatic breakdown. Molecular weight 751.87 g/mol, formula C33H57N11O9. It was developed at the Institute of Molecular Genetics of the Russian Academy of Sciences in the same programme that produced Semax, and the two share the stabilising tail and little else. Semax is built on an ACTH fragment, Selank on an immune peptide. For a researcher that makes Selank the tool for questions at the immune-brain interface rather than the melanocortin axis.

Research has examined Selank across several systems. In the central nervous system, published work has focused on GABA-A receptor modulation, on serotonin turnover in the brainstem and hypothalamus, and on expression of brain-derived neurotrophic factor in the hippocampus. On the immune side, studies have looked at interleukin-6 and the Th1/Th2 cytokine balance, and at inhibition of enkephalin-degrading enzymes, which is the mechanism most often proposed for the findings in rodent stress and anxiety paradigms. Cognitive work has used passive avoidance and maze tasks in rats.

The evidence base has a specific shape a researcher should know before designing around it. Most of the primary literature comes from Russian institutions and appears in Russian-language journals, the samples are small, and the pathway behind the behavioural findings is still argued. That is not a reason to avoid the compound. It is the reason Selank remains an open research question rather than a settled one, which is what makes it worth studying. The full evidence review, study by study, is on the Selank research page linked below.

Each Etched Research vial contains 10mg of Selank as lyophilized powder and ships from the USA in plain packaging. Where an independent laboratory report exists for a compound, the measurements are published on the COA page, including the compounds we hold no report for. Researchers working across both Institute of Molecular Genetics peptides will find Semax 10mg in the same Cognitive category.

Research at a Glance
  • What it is: A synthetic 7-amino-acid peptide developed by Russian researchers, based on a natural fragment called tuftsin.
  • Researchers have studied it for: anxiety and neurasthenia, nootropic (thinking and focus) effects, and how it acts on the GABA calming system.
  • Evidence level: Thin and mostly Russian-language. The human studies are small, and there are no large, independent Western trials confirming them.
  • The short version: Most Selank research is small and published in Russian, and the exact pathway is still an open question. The leading idea points at the brain’s GABA calming system. The human case is not settled, and this is a research summary, not a reason to use anything.

Frequently asked questions

Does the product come with instructions?

No. Etched supplies research materials, not use instructions. Each vial ships labeled with the compound name, the labeled amount, and the lot number, and that is what comes in the box. Etched does not provide instructions for use, dosing, or administration for any product, on the label, on this page, or by email. General laboratory handling notes (storage, what bacteriostatic water is) are on the FAQ page at https://etchedresearch.com/faq/. All products are sold for research use only, not for human consumption.

What is the amount of peptide in this product?

The label reads Selank 10mg. That figure is the labeled net quantity of Selank in the vial, supplied as lyophilized (freeze-dried) powder. It is not the weight of the vial and not a reconstituted volume. Where a Janoshik Analytical report exists for a lot, the measured result for that lot is on the report itself, and the reports that exist are listed on the COA page at https://etchedresearch.com/coa/. Etched ships lyophilized powder only.

Are additional supplies needed?

Nothing else is included, and Etched sells the lyophilized compound only. Bacteriostatic water is sterile water with a small amount of benzyl alcohol added, used in laboratory settings to reconstitute lyophilized (freeze-dried) research peptides into solution. Etched does not sell bacteriostatic water as a product. It is described here only to explain the reconstitution step in a research context. Any supplies a laboratory setting requires are sourced by the researcher.

How is purity verified?

By a third-party laboratory, named. Janoshik Analytical confirms compound identity by mass spectrometry and measures purity by HPLC. Etched does not use vague "third-party tested" language without naming the lab. The measured number for a tested lot is on that lot's report, not a mood word. Where a Janoshik report exists for a compound it is listed on the COA page at https://etchedresearch.com/coa/, and the report itself carries the lot number and the measured purity. Not every listing has a report posted yet, and the COA page shows which do.

Where do products ship from?

Etched ships within the United States only. There is no international shipping. Orders are fulfilled domestically from within the USA. Orders ship in plain, unmarked packaging with no indication of the contents on the outside.

Who is eligible to purchase?

Etched sells to buyers who are 21 years of age or older and who are qualified researchers, research professionals, or affiliated with a research institution, purchasing for in vitro laboratory research. Every order requires an attestation to those three points at checkout, and the order will not process without it. Research Use Only (RUO) means a product is sold only as a material for laboratory and research use. RUO compounds are not drugs, are not approved by the FDA for human consumption, and are not sold or intended for personal use. Shipping is to United States addresses only.
