Frequently Asked Questions
Before reaching out to our support team, please take a moment to visit our FAQ page. We regularly update it with the most accurate and comprehensive information to help answer your questions quickly — saving you valuable time and ensuring a smoother experience.
What are research peptides and compounds?
Research peptides and compounds are synthetic or naturally-derived molecules used in scientific and laboratory studies to explore biological functions, mechanisms of action, and potential therapeutic effects. These products are not approved for human consumption or medical use.
What does "For Research Purposes" mean?
Products are intended strictly for laboratory research and analytical purposes only. They are not approved for human consumption, medical use, therapeutic applications, or diagnostic procedures.
All compounds are supplied to qualified buyers for in vitro research or experimental use in controlled environments. Any reference to clinical data or studies is provided for informational purposes only and does not imply suitability for human use.
What is the shelf life of raw and reconstituted research peptides?
Raw lyophilized (freeze-dried) peptides have a shelf life of 12 to 24 months when stored properly in a cool, dry place, ideally in a freezer or at least in a refrigerator to maintain stability. Once reconstituted with a sterile solvent, peptides generally remain stable for 7 to 30 days when refrigerated, depending on the specific peptide and solvent used. Some peptides may degrade faster, so proper storage is essential. Always follow laboratory guidelines and use reconstituted peptides promptly for research purposes.
Are Certificates of Analysis (COAs) available for your peptide products?
