Description

What is Selank?

Selank is a synthetic peptide and an analog of the naturally occurring peptide tuftsin, which plays a vital role in the immune system. Originally developed by the Institute of Molecular Genetics, Selank is widely recognized for its powerful anxiolytic (anti-anxiety) and nootropic (cognitive-enhancing) properties.

What is it used for?

In research and clinical settings, Selank is primarily studied and utilized for its ability to regulate mood and improve mental clarity. Key benefits and uses include:

  • Anxiety and Stress Reduction: Selank helps alleviate generalized anxiety, social anxiety, and stress by modulating neurotransmitters like serotonin, dopamine, and GABA.
  • Cognitive Enhancement: It improves focus, memory, and learning capacity, making it a popular nootropic.
  • Mood Stabilization: Selank can help stabilize mood swings and combat symptoms of depression.
  • Non-Sedating: Unlike many traditional anti-anxiety medications, Selank does not cause drowsiness, lethargy, or cognitive impairment, allowing users to remain alert and productive.
  • Immune Support: As a tuftsin analog, it also exhibits immunomodulatory effects, helping to support a healthy immune system.

❄ Why bulk buying makes sense: Our peptides arrive lyophilized (freeze-dried powder), which means they are fully shelf stable. Stored in a refrigerator, lyophilized peptides remain stable for 12–24 months. Stored in a freezer, they can last 2–5+ years. Stocking up is a smart, long-term investment in your research supply.

Storage Instructions

All products from LGI peptides are manufactured using a lyophilization (freeze-drying) process. This method is designed to maintain product integrity and allows vials to remain stable during shipping for approximately 3–4 months.

Once a vial is reconstituted with bacteriostatic water, it should be stored in the refrigerator to help maintain stability. Under these conditions, reconstituted material is generally considered stable for up to 30 days.

Lyophilization is a dehydration technique in which compounds are frozen and then exposed to low pressure. This causes the water in the vial to sublimate directly from solid to gas, leaving behind a stable, crystalline white structure. This powder can be kept at room temperature until reconstitution.

Upon receipt, products should be stored away from heat and light. For short-term use, refrigeration at approximately 4°C (39°F) is suitable. For long-term storage (several months to years), vials may be placed in a freezer at approximately -80°C (-112°F). Freezing is the preferred method for preserving product stability over extended periods.

Frequently Asked Questions

Essential information about our research-grade peptides and quality standards.

Peptides are short chains of amino acids linked by peptide bonds, typically consisting of 2-50 amino acids. They serve as the building blocks of proteins and play crucial roles in biological processes.

Research peptides are synthesized versions of naturally occurring peptides, manufactured to precise specifications for use in scientific studies.

Key characteristics: High purity (≥99%), lyophilized form for stability, accompanied by Certificates of Analysis (COA), and manufactured under strict quality control protocols.

Peptide purity refers to the percentage of the target peptide present in a sample, measured via High-Performance Liquid Chromatography (HPLC).

Our Standard: All our research peptides maintain ≥99% purity, verified by third-party laboratory testing and documented in our Certificates of Analysis.

Higher purity is critical for research because impurities can interfere with experimental results and compromise the reproducibility of studies.

All products are supplied in lyophilized powder form within sterile, sealed vials. This format provides:

  • Maximum stability: Extended shelf life compared to liquid solutions
  • Precise measurement: Researchers can work with desired quantities
  • Contamination protection: Sealed vials prevent environmental exposure
  • Shipping durability: Powder form is more stable during transit

Lyophilized peptides:

  • Store at -4°F for long-term storage (up to 24 months)
  • Store at 36-46°F (refrigerated) for short-term storage (up to 3 months)
  • Keep away from light, moisture, and repeated temperature fluctuations
