Overview
Selank is a synthetic heptapeptide derived from tuftsin, a naturally occurring immune-modulating peptide fragment. It has been investigated in experimental and translational research for its potential influence on neurotransmitter regulation, stress-response pathways, and neuroimmune signaling.
Originally developed through peptide research programs exploring neuroactive compounds, Selank has been studied for its interactions with pathways involved in anxiety regulation, cognitive function, and neurochemical balance.
Experimental literature has examined Selank in models assessing:
- stress-response signaling
- neurotransmitter modulation
- cognitive performance pathways
- neuroinflammation markers
- immune system peptide signaling
These studies explore how Selank may influence communication between the central nervous system and immune signaling networks.

Storage Instructions:
All of our products are manufactured using the Lyophilization (Freeze Drying) process, which ensures that our products remain 100% stable for shipping for up to 3-4 months.
Once the peptides are reconstituted (mixed with bacteriostatic water), they must be stored in the fridge to maintain stability. After reconstitution, the peptides will remain stable for up to 30 days.
Lyophilization is a unique dehydration process, also known as cryodesiccation, where the peptides are frozen and then subjected to low pressure. This causes the water in the peptide vial to sublimate directly from solid to gas, leaving behind a stable, crystalline white structure known as lyophilized peptide. The puffy white powder can be stored at room temperature until you’re ready to reconstitute it with bacteriostatic water.
Once peptides have been received, it is imperative that they are kept cold and away from light. If the peptides will be used immediately, or in the next several days, weeks or months, short-term refrigeration under 4C (39F) is generally acceptable. Lyophilized peptides are usually stable at room temperatures for several weeks or more, so if they will be utilized within weeks or months such storage is typically adequate.
However, for longer term storage (several months to years) it is more preferable to store peptides in a freezer at -80C (-112F). When storing peptides for months or even years, freezing is optimal in order to preserve the peptide’s stability.
