Products & Testing

Yes. Every compound is supplied to a 99% purity standard and verified by independent HPLC and mass-spectrometry testing. A Certificate of Analysis is available for each batch in our COA Library.
What form do the compounds come in? +
All peptides are supplied as lyophilized (freeze-dried) powder in sealed vials to preserve stability during storage and shipping.
How should I store them? +
Store sealed, lyophilized vials at −20°C for long-term stability, protected from light and moisture. See our storage & handling guide for research best practices.
How do I verify a batch I received? +
Match the batch number on your vial to its Certificate of Analysis and check the HPLC purity and mass-spec identity. Full instructions are on our COA page.
Research Use & Policy
What does "research use only" mean? +
All products are intended strictly for in-vitro laboratory research and analytical study by qualified professionals. They are not for human or veterinary use, and nothing on this site is medical advice.
Do I need to be a certain age to order? +
Yes. You must be 18 years or older to purchase from King's Compounds.
What is your return policy? +
Due to the nature of research materials, all sales are final. If there's an error with your order, contact us within 48 hours of receipt — details on our Returns & Refunds page.
