The products available on this website are intended solely for in-vitro research purposes (Latin: “in glass”), meaning they are used in experiments conducted outside a living organism. These products are not medicines or drugs, have not been evaluated or approved by the U.S. Food and Drug Administration (FDA), and are not intended to diagnose, treat, cure, or prevent any disease or medical condition. Any administration to humans or animals, whether by ingestion, injection, or other means, is strictly prohibited by law.
Our peptides are produced exclusively for laboratory and scientific research purposes.
Licensed Peptides™ products are developed using industry-standard synthesis and purification protocols, making them suitable for in vitro research, analytical testing, and experimental models.

Our peptides are commonly used in research involving:
All products are intended for research use only and are not for human or animal consumption, therapeutic use, or clinical application.
At Licensed Peptides™, quality isn’t a claim. it’s a controlled, repeatable process.
Every peptide we produce follows a strict, pharma-grade workflow designed to ensure purity, stability, and consistency from synthesis to delivery.
All peptides are synthesized in sterile, controlled environments to eliminate contamination risk and ensure batch consistency.
We use advanced High-Performance Liquid Chromatography (HPLC) to separate and verify peptide purity with precision.

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.
