What is Selank?
Selank is a synthetic heptapeptide derived from the endogenous immunopeptide tuftsin, with the sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro. It carries the molecular formula C33H57N11O9, a molecular weight of 751.9 g/mol and CAS number 129954-34-3. Kovalabs supplies it as a lyophilised solid for laboratory research use only.
It is also catalogued under the synonym TP-7 and identified in PubChem under CID 11765600. Selank is a peptide, not a steroid or small-molecule drug, and Kovalabs supplies it strictly as a reference compound for non-clinical investigation.
Is Selank legal in the UK?
Selank is not a controlled drug under the Misuse of Drugs Act 1971 and possessing the research material is not in itself prohibited. It is supplied for laboratory research use only and cannot be sold or marketed for human or veterinary consumption. It is not a licensed medicine and holds no marketing authorisation in the UK. The buyer is responsible for compliance with applicable laws in their jurisdiction. See our research disclaimer for the full terms of supply.
How is identity and quality assured?
Each batch is released after independent identity and purity testing. Purity is assessed by HPLC at 99% or higher, and identity is confirmed by HPLC retention-time matching (HPLC-RTM) against a reference standard for CAS 129954-34-3 and formula C33H57N11O9. A certificate of analysis accompanies the batch so the recorded identity and purity can be checked against the verified identifiers above. Batch documents are available on our certificates of analysis page.
What does the research on Selank investigate?
As a tuftsin analog, Selank appears in the published literature on neuropeptide signalling in pre-clinical and in-vitro model systems. None of that work establishes a benefit, effect or outcome in humans, and Selank is not a licensed medicine. Reported observations are research-context findings only. The mechanistic and citation detail is handled in our Selank research monograph, not on this product page.
Synthesis and supply
Selank is supplied as a lyophilised white to off-white powder. For bench work it is reconstituted with a solvent such as bacteriostatic water; this is a laboratory preparation step, not a human-use instruction. Store the lyophilised solid at -20C, dry and protected from light, and hold reconstituted material at 2-8C. Browse the full neuropeptides category, or compare related research peptides such as Semax and DSIP.

Common questions
- What is Selank?
- Selank is a synthetic heptapeptide derived from the endogenous immunopeptide tuftsin, with the sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro. It has the molecular formula C33H57N11O9, a molecular weight of 751.9 g/mol and CAS number 129954-34-3. Kovalabs supplies it as a lyophilised powder for laboratory research use only, not for human or veterinary use.
- Is Selank legal in the UK?
- Selank is not a controlled drug under the Misuse of Drugs Act 1971, so possessing the research material is not in itself prohibited. It is supplied for laboratory research use only and cannot be sold or marketed for human or veterinary consumption. It is not a licensed medicine and holds no UK marketing authorisation. The buyer is responsible for compliance in their jurisdiction.
- Is Selank intended for human use?
- No. Selank is supplied solely as a reference compound for non-clinical laboratory research. It is not intended, packaged or authorised for human or veterinary use, and no human or veterinary application is implied. It is not a licensed medicine and must not be consumed.
- What is the Selank peptide sequence?
- Selank has the amino acid sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro, a seven-residue heptapeptide. Its molecular formula is C33H57N11O9 and its molecular weight is 751.9 g/mol. These identifiers are confirmed against each batch certificate of analysis.
- What is the CAS number and PubChem CID for Selank?
- Selank has CAS number 129954-34-3 and is listed in PubChem under CID 11765600. The molecular formula is C33H57N11O9 with a molecular weight of 751.9 g/mol. The synonym TP-7 also refers to this compound. These identifiers let you verify identity independently against the batch documentation.
- Is all Selank the same?
- No. Purity and identity vary by supplier and batch, which is why a certificate of analysis matters. Kovalabs releases each batch only after independent testing, with purity assessed by HPLC at 99% or higher and identity confirmed by HPLC retention-time matching (HPLC-RTM) against a reference standard for CAS 129954-34-3. Batch documents are available on the certificates of analysis page.
- How is Selank supplied and reconstituted?
- Selank is supplied as a lyophilised white to off-white powder. For laboratory work it is reconstituted with a solvent such as bacteriostatic water. This is a research-bench preparation step and not a human-use instruction. The labelled vial strength is a product specification, not a dose.
- How should Selank be stored?
- Store the lyophilised solid at -20C, kept dry and protected from light. Once reconstituted, hold the material at 2-8C. Correct storage preserves peptide integrity for laboratory research. Selank is for laboratory research use only and not for human or veterinary use.
- Is Selank a peptide or a steroid?
- Selank is a peptide, specifically a synthetic heptapeptide analog of the immunopeptide tuftsin. It is not a steroid or a small-molecule drug. Its identity is defined by the sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro and the molecular formula C33H57N11O9.
- What is the difference between Selank and Semax?
- Selank and Semax are distinct synthetic peptides with different sequences and molecular identifiers; Selank is a tuftsin-derived heptapeptide (CAS 129954-34-3). Both are catalogued as research peptides in the neuropeptides category and supplied for laboratory research use only. Compare the two on their individual product pages and certificates of analysis.
- Where can I buy Selank in the UK?
- Kovalabs supplies Selank in the UK with batch certificate of analysis and UK despatch. It is sold for laboratory research use only and cannot be supplied for human or veterinary consumption. Browse the neuropeptides category for related research peptides.
- Does a certificate of analysis come with Selank?
- Yes. Each batch of Selank is released after independent identity and purity testing, and a certificate of analysis documents the result. Purity is assessed by HPLC at 99% or higher and identity is confirmed against CAS 129954-34-3 and formula C33H57N11O9. Batch documents are listed on our certificates of analysis page.
- Is Selank a licensed medicine?
- No. Selank is not a licensed medicine and holds no marketing authorisation in the UK. It is a research chemical supplied for laboratory research use only. It is not intended to diagnose, treat, cure or prevent any condition, and no therapeutic claim is made.
