Research peptides are short chains of amino acids used in laboratory and scientific research to study biological processes including cellular signaling, tissue repair, metabolic function, and aging mechanisms. They are not approved drugs and are not intended for human consumption.
Every batch in our catalog is submitted to an independent, US-based analytical laboratory before it's listed for sale. Testing includes HPLC (High-Performance Liquid Chromatography) to determine purity percentage, and Mass Spectrometry to confirm molecular identity — two separate methods on every compound.
Our compounds average 99%+ HPLC-verified purity. The exact figure for each batch is published in the batch-specific Certificate of Analysis available on every product page.
A COA is a document from the testing laboratory that records the analytical results for a specific batch of compound. It includes the HPLC purity percentage and Mass Spectrometry identity confirmation. The batch number on the COA should match the lot number on your vial. Our Education Hub includes a step-by-step guide to reading a peptide COA

Lyophilized peptides are shipped in sealed vials with appropriate cold-chain packaging to maintain compound integrity in transit. Every order includes the relevant COA documentation.
Research peptides sold for in-vitro laboratory use exist in a complex regulatory environment that varies by compound and jurisdiction. JDD sells exclusively for research purposes. Customers are responsible for understanding and complying with all applicable laws in their location, including any FDA restrictions that may apply to specific compounds. We recommend consulting legal counsel if you have specific compliance questions.
No. Our products are not FDA approved and are not intended for human or veterinary use. They are sold strictly for in-vitro laboratory and research purposes.
Research use only means the product is intended for controlled laboratory and scientific study — not for administration to humans or animals outside of approved clinical research protocols. Purchasers of JDD products confirm they are qualified researchers and assume responsibility for appropriate use.
