Selank Peptide | 5mg | Research Grade

Selank UK availability is one of the most common research queries we receive — this page covers everything you need before ordering, including mechanism, purity testing, and storage guidance.

What Is Selank?

Selank is a synthetic heptapeptide originally developed by researchers as an analogue of Tuftsin, a naturally occurring immunomodulatory peptide. It was engineered specifically to extend Tuftsin’s stability profile for laboratory research applications, giving researchers a more robust compound to work with in extended study designs.

ApexPure supplies Selank 5mg as a lyophilised, research-grade compound intended exclusively for laboratory investigation. It is studied for its interaction with several neurochemical systems, and its heptapeptide structure has made it a frequent subject of comparative research alongside other short-chain neuroactive peptides such as Semax.

Research Applications

Selank is studied within neuropharmacology research for its interaction with GABAergic and monoamine neurotransmitter systems. It is referenced in published literature covering anxiety-pathway models, stress-response research, and cognitive-function assays conducted in laboratory animal studies. Researchers have also examined its relationship to BDNF (brain-derived neurotrophic factor) expression in neuroscience research contexts, positioning it within the broader category of nootropic-adjacent research peptides.

Background & Research History

Selank was developed in Russia during peptide research programmes focused on immunomodulatory and neuroactive compounds, building on earlier Tuftsin research. Over time, research interest shifted increasingly toward its neurobehavioural research profile rather than its original immunomodulatory research context, and it is now most commonly referenced in literature exploring stress and cognitive-pathway research models rather than immune-function studies.

Purity & Third-Party Testing

ApexPure’s Selank is HPLC-verified to a minimum of 99% purity by an independent testing laboratory, with a downloadable, batch-specific Certificate of Analysis available for every lot we sell. This documentation confirms both compound identity and purity level ahead of any laboratory use.

Reconstitution & Storage Guidelines

Store the lyophilised vial frozen at -18°C or below, protected from light and moisture. Once reconstituted with bacteriostatic water, refrigerate the solution at 2–8°C and minimise freeze-thaw cycling to protect peptide stability across your research timeline.

Handling Notes for Researchers

Selank should be handled only by qualified laboratory personnel in a controlled research environment, following your institution’s standard operating procedures for peptide handling, reconstitution, and disposal. ApexPure does not provide dosing or administration guidance, as this compound is supplied strictly for laboratory research.

Why Buy Selank UK From ApexPure

ApexPure was built around one standard: every batch we sell is independently tested before it reaches your laboratory, and every Certificate of Analysis is published, not hidden behind a support request. Selank and Semax are frequently studied together, and we stock both under Research Peptides so laboratories can source their full nootropic-research protocol from a single, consistently tested supplier. Orders are dispatched from the UK, so researchers avoid the customs delays and cold-chain uncertainty that come with importing from overseas suppliers. If a batch does not meet our purity threshold, it does not go on sale — that is the certification promise behind the ApexPure name. Read more about our testing process, or check our FAQ for common questions about ordering and dispatch. Our facility operates under documented quality-control procedures, with every incoming batch checked against its accompanying Certificate of Analysis before it is released into inventory. We work with independent, third-party laboratories rather than relying on internal or manufacturer-supplied test data, which is a distinction researchers increasingly look for when comparing UK suppliers. Packaging is designed to protect peptide integrity in transit, and orders are typically dispatched within one to two working days of purchase.

Frequently Asked Questions

What is Selank studied for in research settings?

Selank appears in published literature relating to neurobehavioural and stress-pathway research models. ApexPure makes no therapeutic claims about this compound and supplies it strictly for laboratory investigation.

Is Selank the same as Semax?

No — both are nootropic-research peptides studied in similar research contexts, but they have distinct amino acid sequences and are referenced in different areas of the neuroscience literature. ApexPure stocks both under Research Peptides.

What purity standard does ApexPure test Selank to?

Every batch is independently HPLC-verified to a minimum of 99% purity before release.
