Selank is a synthetic peptide analogue of tuftsin, an endogenous immunomodulatory peptide naturally involved in biological signaling processes. Originally developed in Russia, Selank has been studied primarily for its activity within the central nervous system and its interaction with neurotransmitter-related signaling pathways.
Researchers have investigated Selank for its potential influence on GABAergic signaling, as well as broader neurochemical systems involving serotonin, dopamine, and related pathways. Because of these interactions, Selank has attracted scientific interest in neuroscience, neuroendocrine communication, and peptide-based CNS research.
Selank is widely studied for its role in central nervous system signaling. Experimental research suggests that the peptide may influence pathways related to neuronal communication and neurotransmitter balance, particularly within GABA-associated systems.
Scientists continue to investigate how Selank may affect receptor-related signaling mechanisms and how these interactions influence broader CNS activity in laboratory models.
One of the primary research areas involving Selank is its relationship with GABAergic neurotransmission. Studies have explored how the peptide may influence the expression of genes associated with GABA signaling and receptor-related communication in experimental systems.
This has made Selank a molecule of interest in ongoing research focused on inhibitory neurotransmission and peptide-mediated CNS signaling.
Selank has also been studied in connection with cognitive signaling pathways and broader neurobiological activity. Researchers continue to examine how this peptide may influence processes related to memory-related signaling, learning pathways, and neuronal communication.
Its CNS activity has led to broader scientific interest in Selank as part of peptide research involving cognition and neurobiology.
Because Selank is derived from a tuftsin analogue, it has also attracted attention in studies involving the intersection of immune signaling and neuroendocrine communication. Researchers are exploring how peptide signaling may influence these interconnected biological systems in experimental environments.
These investigations continue to expand understanding of how endogenous peptide analogues participate in broader regulatory pathways.
Current scientific interest in Selank includes research involving:
GABA-related signaling pathways
Central nervous system communication
Cognitive and neurobiology research
Neurotransmitter pathway studies
Neuroendocrine and immune signaling interactions
These areas remain active fields of investigation in peptide and neuroscience research.

Peptides are short chains of amino acids that act as signaling molecules within the body. They are involved in a wide range of biological processes, including tissue repair, immune response, and cellular communication.
In research settings, peptides are studied for their ability to interact with specific receptors and pathways, making them valuable tools for scientific and laboratory analysis.
All peptides sold by Polar Peptides are intended strictly for research and laboratory use only and are not approved for human consumption.
All peptides are supplied in lyophilized (freeze-dried) form to ensure long-term stability during storage and shipping.
Unreconstituted vials should be stored in a cool, dry place away from direct light. For extended storage, refrigeration is recommended.
Once reconstituted for research purposes, peptides should be kept refrigerated and handled using sterile laboratory practices to maintain integrity.
Proper storage and handling are essential to preserve peptide stability, purity, and accuracy in research applications.
All orders are shipped directly from our Canadian fulfillment centre within 24 hours (Monday–Friday), ensuring fast and reliable shipping for all peptide products.
Delivery typically takes 2–5 business days depending on your location and the shipping method selected at checkout. We partner with trusted carriers to ensure secure and temperature-stable transit where required.
Once your order ships, a confirmation email with a real-time tracking number will be sent so you can monitor your package every step of the way.
We are committed to providing fast delivery across Canada, making Polar Peptides one of the most reliable peptide suppliers in the country.
We currently accept secure payments via Interac e-Transfer, the safest and fastest method for Canadian customers purchasing research peptides.
After placing your order, you will automatically receive an email with clear and detailed payment instructions. This ensures accurate payment processing and helps us ship your order without delay.
Your order will be prepared and shipped as soon as payment is successfully received and confirmed by our system.

We strive to make the payment process simple, safe, and smooth for all customers purchasing peptides in Canada.
Each vial contains peptides at approximately 104% of the labeled amount, providing full accuracy and consistency for research applications.
All vials arrive as lyophilized (freeze-dried) powder requiring reconstitution with bacteriostatic water . This is necessary because once reconstituted with liquid, they must be refrigerated to maintain stability. We do not ship reconstituted peptides.
Vial dimensions are standardized at 16mm diameter and 38mm height, with a maximum fill capacity of 3ml. This ensures compatibility with common research-use storage and reconstitution tools.
Our packaging and vial quality meet high industry standards, offering consistent quality across all peptide batches.
All peptides offered by Polar Peptides undergo strict quality-control procedures, including independent third-party analytical testing for purity, identity, and consistency.
We use advanced testing methods such as HPLC (High-Performance Liquid Chromatography) and Mass Spectrometry to verify that each peptide meets the required research-grade standards.
Every batch is tested before being released, and full Certificates of Analysis (COAs) can be provided upon request. This includes data on purity percentage, molecular confirmation, and batch identification.
For the most up-to-date COAs and lab documentation, simply email us and our team will send the current testing reports for the specific peptide(s) you are interested in.
We are committed to transparency, accuracy, and reliability—ensuring that researchers across Canada receive high-quality, fully verified peptide products every time.
Note: Due to factors such as U.S. cross-border shipping delays, laboratory backlog, and the fact that we offer over 40 different products, it is not always possible to have up-to-date or readily available COAs for every batch. We always strive to provide them when possible, but please understand that COAs may not always be available immediately.
