All of our peptides are research-grade with a minimum purity of 99%, verified by third-party testing. Certificates of Analysis (COAs) are available for every product.

Peptides should be stored in a cool, dry place away from direct sunlight. For long-term storage, we recommend keeping them refrigerated or frozen. Always handle peptides in a clean environment using proper laboratory equipment.

When stored properly, lyophilized (freeze-dried) peptides have a shelf life of up to 24 months. Once reconstituted, peptides should be used within 28 days if refrigerated.

COAs are available on each product page. You can also request a COA directly by contacting our support team with your product name or order number.
