Frequently Asked Questions!

Our peptides are intended for scientific research, particularly in the fields of biochemistry, cell biology, and pharmacology. They are commonly used in cell signaling studies, protein interaction research, and animal models to explore biological mechanisms and therapeutic pathways.
Each batch of our peptides undergoes rigorous testing in certified laboratories. We provide Certificates of Analysis (COAs) for each product to verify purity, identity, and potency. Additionally, our peptides are tested for consistency to ensure they meet the highest standards required for research use.
No, our peptides are strictly for research and laboratory use only. They are not approved for human consumption or medical use. We provide them exclusively to qualified professionals and research facilities conducting scientific studies.
Our peptides are lyophilized (freeze-dried) to maintain stability and purity. When stored properly in a cool, dry place, they typically have a shelf life of up to two years from the date of manufacture. Always refer to the specific batch Certificate of Analysis (COA) for the exact expiry date.
For optimal stability, store lyophilized peptides in a cool, dry environment at 2-8°C (36-46°F). Avoid storing them at room temperature or in humid conditions. If you plan to use them over an extended period, freezing can help maintain their integrity.
