What is Selank?
Selank is a chain of seven amino acids. Four of them are copied from tuftsin, a short natural chain that comes from an antibody protein, and the other three are added on the end to slow it being broken down. It came out of a Russian research program in Moscow, and the published work is mostly in rats and mice, with some in cultured human cells and some clinical research in Russia. Tuftsin itself has its own separate research behind it, and none of that is research on this chain.

Selank Research & Reference
What Selank does in published studies, and how to work with it in the laboratory, are covered in full on two dedicated pages rather than summarised here, so neither the evidence nor the handling detail is cut short.

Frequently Asked Questions
Is Selank third-party tested for purity?+−
Yes. Every batch of Selank is tested by an independent third-party laboratory using HPLC and MS-UPLC, confirming purity and mass identity before the batch is released. Pure Peptides does not test its own material.
Can I see the Certificate of Analysis before buying?+−
Yes. The Certificate of Analysis for the batch currently in stock can be viewed and downloaded directly on this page, before you place an order. Each certificate states the batch number, the measured purity, and the date of analysis, and can be verified independently with the issuing laboratory using the report number it carries.
What does "Research Use Only" mean?+−
It means Selank is supplied for in-vitro laboratory research and for no other purpose, and must not be administered to humans or animals. Selank is legal to purchase in the United States for in vitro and non-clinical laboratory research, and is not a scheduled substance under the Controlled Substances Act. It holds no FDA or MHRA marketing authorisation. Sold strictly for qualified research use, not human or veterinary administration.
How is Selank shipped and stored?+−
Selank ships from US stock with cold-chain packaging and full tracking; orders placed before noon EST on business days are typically dispatched the same business day. On arrival, store the lyophilized powder at -20°C or below, dry and protected from light.
Does Selank act on GABA signaling?+−
One published study reports that applying Selank to rat hippocampal slices increased both the amplitude and the frequency of spontaneous inhibitory currents. The same study found no significant dose-dependence across the concentrations tested, and reported that in some neurons the increase was preceded by a transient decrease. An earlier patch-clamp study from the same laboratory reported that Selank raised the frequency of spike-dependent spontaneous inhibitory currents in rat CA1 pyramidal cells, while spike-independent currents were unchanged. Those two studies are the direct electrophysiological evidence found.
Is research on tuftsin research on Selank?+−
No. Tuftsin is a natural four-residue peptide derived from immunoglobulin G, with its own immunological literature. Selank is that sequence with three further residues, Pro-Gly-Pro, attached at one end. They are different compounds, and no tuftsin finding appears on this page.
