Research peptides are short chains of amino acids manufactured for use in scientific and laboratory research. They are synthetic compounds produced to high purity standards and are used in various fields including biochemistry, pharmacology, and molecular biology for in vitro studies and research applications.

Lyophilized (freeze-dried) peptides should be stored at -20°C for long-term storage or at 2-8°C (refrigerated) for short-term storage. Keep them in a cool, dry place away from direct sunlight. Reconstituted peptides should be refrigerated at 2-8°C and used within the timeframe specified on the product documentation. Avoid repeated freeze-thaw cycles.

Yes, every batch is tested by independent third-party laboratories using HPLC (High-Performance Liquid Chromatography) for purity analysis and LC-MS (Liquid Chromatography-Mass Spectrometry) for identity verification. Batch-specific Certificates of Analysis are available for download on each product page and in our COA Library.

A Certificate of Analysis (COA) is a quality assurance document issued by a testing laboratory that verifies a product meets specified quality standards. For peptides, a COA typically includes purity results (via HPLC), identity confirmation (via mass spectrometry), appearance, batch/lot number, and the testing laboratory's information.

COAs are available in two places: directly on each product page under the "Certificate of Analysis" section, and in our centralized COA Library where you can search by product name or batch number.

"Research Use Only" (RUO) means that our products are sold exclusively for legitimate scientific and laboratory research purposes. They are not intended, marketed, or sold for human consumption, veterinary use, diagnostic purposes, or any therapeutic application. By purchasing from The Peptide Store, customers agree that all products will be used solely for research purposes in compliance with all applicable laws and regulations.

We accept returns for damaged or defective products within 14 days of delivery. Products must be in their original, unopened condition. Due to the nature of research chemicals, opened or used products cannot be returned. Please see our full Refund & Return Policy for complete details.
