Overview
Selank is a synthetic heptapeptide (Thr-Lys-Pro-Arg-Pro-Gly-Pro), an analogue of the immunomodulatory peptide tuftsin. It is supplied as a lyophilised powder for laboratory research.
It is studied in vitro and in preclinical models for anxiolytic activity, GABAergic and monoamine signalling, BDNF expression and cytokine balance, with no tolerance reported in those models. It is supplied as a research reference material only and is not for human or animal consumption.
Selank in published research
Selank was developed at the Institute of Molecular Genetics of the Russian Academy of Sciences as a stabilised analogue of tuftsin (Thr-Lys-Pro-Arg), a short immunomodulatory peptide. Adding Pro-Gly-Pro to the tuftsin sequence slows its breakdown by peptidases.
In rodent studies it has been examined for anxiolytic-like behaviour, for its effect on the enzymes that break down enkephalins, and for changes in the expression of GABA-related genes. Other work has measured cytokines such as IL-6 in immunological research models. As with Semax, many of the animal studies used intranasal delivery, which is why an intranasal research kit is offered alongside it.
Selank or N-Acetyl Selank?
This listing is standard Selank (CAS 129954-34-3). It is not N-Acetyl Selank Amidate, a modified form with an acetylated N-terminus and an amidated C-terminus that is sold separately elsewhere. Check which form a protocol specifies before ordering.
Selank vs Semax
Selank and Semax come from the same institute and share the Pro-Gly-Pro stabilising tail, but they derive from different parent peptides: Selank from tuftsin, Semax from ACTH. Selank research tends to centre on anxiolytic-type and immune-related endpoints, Semax research on neurotrophic signalling. Both are stocked here, and the Semax vs Selank guide below covers the differences in more detail.
Buying Selank in the UK
North Peptides UK holds Selank in stock in the UK and sends it by tracked delivery, so there is no import wait or customs hold. Each vial contains 30mg of lyophilised Selank at supplier-stated purity, kept frozen until it leaves us, and supplier documentation is available on request where held. Bacteriostatic water and the intranasal research kit can be added before checkout.

Storage and handling
Supplied as a lyophilised powder in a sealed vial and kept frozen until dispatch. Unopened vials are typically stored at -20°C for the long term and 2-8°C for short periods. After reconstitution with bacteriostatic water, vials are generally refrigerated at 2-8°C, protected from light, and not subjected to repeated freeze-thaw cycles.

Questions
What is Selank?
A synthetic heptapeptide analogue of the immunomodulatory peptide tuftsin, supplied as a 30mg lyophilised vial for research.
What is Selank supplied as?
A 30mg lyophilised vial with supplier-stated purity and stored frozen until dispatch. Supplier documentation is available on request where held.
Do you stock Selank in the UK?
Yes. It is UK stocked with dispatch within 24–48 hours of confirmed payment on business days via tracked delivery.
Is Selank for research use only?
Yes. It is supplied strictly for laboratory research and is not for human or animal consumption.
Is this Selank or N-Acetyl Selank?
This is standard Selank (Thr-Lys-Pro-Arg-Pro-Gly-Pro, CAS 129954-34-3). It is not N-Acetyl Selank Amidate, a modified form with an acetylated N-terminus and an amidated C-terminus.
What is the difference between Selank and Semax?
Both were developed at the same Russian institute and share a Pro-Gly-Pro stabilising tail, but they come from different parent peptides: Selank from tuftsin, Semax from ACTH(4-7). Selank research centres on anxiolytic-type and immune-related endpoints; Semax research on neurotrophic signalling such as BDNF.
Where can I buy Selank in the UK?
North Peptides UK stocks Selank in the UK as a 30mg lyophilised vial, sent by tracked delivery within 24–48 hours of confirmed payment, with bacteriostatic water and an intranasal research kit available as add-ons.
