How orders are packed, shipped, and handled after they leave us.
Peptides are lyophilized and securely sealed for transit. Lyophilized material is stable for standard shipping; refrigerate or freeze on arrival per the storage guidance on each product page. Inspect your shipment on arrival.
Every lot is tested and released against specification before it ships. Quality records are retained on file for each lot; printed documents are not included in the shipment.
Because these are sensitive research materials, opened products cannot be returned. If a product arrives damaged or does not match its specification, contact us within 7 days for a replacement or refund.
