Selank 5mg – High-Purity Research Peptide
Selank is a synthetic peptide analogue of the naturally occurring immunomodulatory peptide tuftsin, investigated in preclinical research for its potential anxiolytic, neuroprotective, and cognitive-enhancing effects. Supplied as a lyophilised (freeze-dried) solid to preserve stability, this compound is verified at >99.1% purity (HPLC-tested) and provided with full Certificates of Analysis (COAs).
What is Selank?

Research Applications of Selank
Preclinical and laboratory studies have investigated Selank for potential roles in:
Anxiolytic Effects – Studied for its ability to modulate GABAergic and serotonergic pathways, reducing anxiety-like behaviours without sedation.
Cognitive Support and Neuroprotection – Explored for its influence on memory, learning, and mental clarity, potentially linked to brain-derived neurotrophic factor (BDNF).
Immune Modulation – Research suggests Selank may contribute to immune system regulation, particularly under stress or inflammatory conditions.

Impressed with the customer service! I used the chat bot on the weekend, expecting not to get a reply till Monday but I had a response is 3 minutes. They helped with my questions and were very knowledgeable- was clearly a human I was speaking to rather than those stupid bots and they helped me out so much. Caring about the customer’s experience is so key and they nail this.

This has been life changing for me
I’ve struggled with social anxiety for years. Public speaking was a nightmare and even small talk drained me. After a week on Selank I noticed I could walk into meetings without that heart racing panic. I still get nervous but it’s manageable. I feel present instead of trapped in my own head. My coworkers even commented that I seemed more confident.
