Research peptides are synthetic amino acid chains manufactured for use in scientific research and laboratory experiments. They are not intended for human or veterinary use. Our peptides are produced under strict quality controls and verified through independent third-party testing.
Research peptides are legal to purchase and possess in most jurisdictions when sold strictly for in vitro research purposes. These products are not approved by the FDA or any equivalent regulatory body for human or veterinary use. It is the buyer's sole responsibility to verify that purchase and possession for in vitro research is lawful in their jurisdiction and to comply with all applicable federal, state, local, and international regulations. All purchases must be made by qualified researchers or institutions conducting bona fide research.
A COA is a document from an independent testing laboratory that verifies the identity, purity, and quality of a specific batch of product. Every product we sell includes a COA, which you can download from the product page or our COA library.
All of our peptides are manufactured to a minimum 99% purity standard. Each batch is verified through HPLC (High Performance Liquid Chromatography) and Mass Spectrometry testing by independent laboratories. The exact purity percentage is listed on each product page.
Lyophilized (freeze-dried) peptides should be stored at -20°C for long-term storage. Once reconstituted, store at 2-8°C (refrigerator) and use within the timeframe specified on the product documentation. Avoid repeated freeze-thaw cycles.
