# Selank - Selank (TKPRPGP) - a synthetic tuftsin-analog heptapeptide, also indexed as TP-7, supplied freeze-dried for laboratory research. Selank (TKPRPGP, TP-7) tuftsin-analog research-use-only peptide - freeze-dried, historical sample report on file, dispatched from Perth. ## At a glance | | | | --- | --- | | Compound | Selank | | Descriptor | TKPRPGP tuftsin-analog study material | | Current certificate | Not verified for listed lot | | Storage | 2-8 C | | Format | Freeze-dried powder | | Availability | Out of stock | | Lot | SELANK-2506 | ## Sizes and pricing (AUD) | | | | --- | --- | | 11 mg | $99 AUD | ## Certificate status Matching current certificate unavailable. No verified report matches the listed compound, lot and amount. Historical sample report: Selank, 11 mg, lot FL20260410-SELANK-11. Test: Heavy metals analysis. This report does not verify the listed item or lot; a document mismatch does not establish the physical product's contents. ## What Selank is Selank is a synthetic heptapeptide: a seven-amino-acid peptide with the sequence TKPRPGP, written in full as Thr-Lys-Pro-Arg-Pro-Gly-Pro. It is also indexed in research as TP-7. It is described as a tuftsin analog. The first four amino acids match tuftsin, TKPR, and the added Pro-Gly-Pro tail is the structure note that appears across the Selank literature. Its registry details are CAS 129954-34-3, molecular formula C33H57N11O9, and molecular weight about 751.9 g/mol. Regulatory context: developed and used in Russia as an anxiolytic and sold in Russian pharmacies, but not approved by the TGA (Australia) or the FDA (US), and no marketing authorisation in the EU. ## Specifications The basics at a glance: sequence, synonym, structure note, CAS, formula, molecular weight, format, storage, and current lot. A sample report only covers the compound, amount, lot and tests it names. | | | | --- | --- | | Compound | Selank | | Synonyms | TP-7 / Selank | | Sequence | Thr-Lys-Pro-Arg-Pro-Gly-Pro / TKPRPGP | | Length | 7 amino acids | | CAS | 129954-34-3 | | Molecular formula | C33H57N11O9 | | Molecular weight | About 751.9 g/mol | | Structure note | Tuftsin analog; first four amino acids match tuftsin TKPR, followed by Pro-Gly-Pro | | Format | Freeze-dried research reference | | Storage | 2-8 C, protect from light | | Lot | SELANK-2506 | ## What Selank research looks at Published studies describe Selank through TP-7 sequence identity, tuftsin-analog structure, and work on anxiety-related behaviour, BDNF, immune/cytokine markers, and GABA/serotonin systems. Those papers include Russian clinical research, animal studies, gene-expression records, and receptor-system experiments. This page treats them as study context only, not as claims about a Form Laboratories product. The available historical report covers a different lot; it does not verify SELANK-2506. ## Frequently asked questions ### What is Selank supplied for? Selank is supplied as laboratory research material only. It is 21+ only, not for human consumption, and not for veterinary use. ### Does this page include matching COA information? The product page lists catalog lot, appearance and storage notes for Selank. Available original reports are labelled by sample; matching current certification is unavailable where the compound, lot or amount differs. A heavy-metals screen does not measure purity or confirm identity. ### How should the vial be handled after delivery? Follow the label and your laboratory's written procedures. Do not treat a historical sample report as current lot documentation. This page repeats 2-8 C storage guidance and light-protection notes before checkout. ### What is Selank? Selank is a synthetic heptapeptide with the sequence TKPRPGP, developed in Russia at the Institute of Molecular Genetics as an analog of the natural peptide tuftsin. It is studied in published research for anxiety-related behaviour and immune-marker systems, mostly in animal studies plus some Russian clinical research. Form Laboratories supplies Selank strictly as research-use-only reference material, not for human or veterinary use. ### What is the Selank peptide sequence? Selank's sequence is TKPRPGP, written in full as Thr-Lys-Pro-Arg-Pro-Gly-Pro. The first four amino acids match tuftsin TKPR, and a Pro-Gly-Pro tail is added. It is also indexed as TP-7; CAS 129954-34-3, molecular formula C33H57N11O9, molecular weight about 751.9 g/mol. ### Is Selank approved anywhere? Selank is developed and used in Russia as an anxiolytic and sold in Russian pharmacies, but not approved by the TGA (Australia) or the FDA (US), and no marketing authorisation in the EU. Form Laboratories supplies it only as research-use-only reference material, not as a medicine and not for human or veterinary use. ## References - Zozulya 2008: Zozulya AA et al.
