Selank

SELANK

Selank peptide is a short, synthetic analogue of tuftsin with potent anti-anxiety effects. It has been shown to improve memory, enhance learning, and positively influence pain perception. As a nootropic and anxiolytic compound, Selank is of increasing interest in neurological and cognitive research.

Selank is a small, lab-made peptide inspired by a natural immune fragment (tuftsin). Researchers use it to explore brain-signaling pathways linked to calm focus, mood balance, and attention—think of it as a simple tool for probing how “settling” signals and cognitive circuits interact in controlled models.

In preclinical and early research settings, Selank is discussed around outcomes like anxious-type behavior, working memory, and attention tasks, as well as how sensory inputs are processed. Teams often look at neurotransmitter-related readouts and stress-response markers to see whether signaling shifts under defined conditions. These are research findings, not medical claims, and results vary by model and protocol.

What sets our Selank apart is clean, verified quality. Each batch is identity-confirmed (e.g., mass spectrometry) and purity-checked by HPLC, with ≥99% purity (typical). You get a lot-specific Certificate of Analysis (COA) with real data—proof of identity, purity, and an analytical “fingerprint” you can cite in your records.

We keep specifications tight and track every lot number so you can reorder the same analytical profile you liked before. That consistency helps reduce variability when you repeat methods, compare conditions, or extend prior work across cohorts.

If you value clarity over hype, Selank from AI Peptides delivers exactly what researchers ask for: verified identity, high purity, and transparent documentation—so you can focus on the science with confidence.

Not for human or veterinary use. Made in USA

This product is intended as a research chemical only. Not for human use. Peptides will arrive in a lyophilized (powder) form for maximum stability.

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.
