No — and they don’t need to. Our products ship as lyophilized (freeze-dried) powder, which is stable at ambient temperature for normal shipping durations. Cold-chain packaging is designed for materials already in solution, which are far more sensitive to temperature. In dry powder form, the water that drives degradation has already been removed, so a few days at room temperature during transit does not meaningfully affect the material. Refrigeration matters for long-term storage and after reconstitution — not for shipping powder.

• Shipped ambient, FedEx 2-Day Air

The majority of orders are processed and dispatched within 36 hours of purchase. Residential orders inside the United States then travel by FedEx 2-Day Air. Processing time is separate from transit time, and both are estimates rather than guarantees. If an order has not been dispatched within that window, contact the support team — a delay is usually stock availability or a backordered item.

• Shipping Policy — Order Processing, Shipping Method

Shipment protection is an optional add-on you select at checkout. It is what covers you if a package is lost, delayed, or damaged in transit. Orders placed without it are not eligible for reimbursement or replacement: once the package is handed to FedEx, liability for transit transfers to the carrier, and the recourse is a claim filed with them. It is inexpensive relative to the order value, and we recommend it — especially for addresses where packages sit unattended.

• Shipping Policy — Lost, Delayed, or Damaged Packages

It means these products are sold for laboratory and in-vitro research only. They are not intended for human or veterinary use, not for consumption or administration in any form, and not for use as drugs, supplements, foods, or cosmetics. Nothing we sell is intended to diagnose, treat, cure, or prevent any disease or condition. By ordering you are confirming you are at least 21, and that you have the qualifications and facilities to handle the material safely and lawfully.

• Legal Disclaimer

A COA reflects what testing found in a specific sample, using specific methods, at the time of testing. It does not guarantee a particular research result, does not establish suitability for your application, and does not account for anything that happens after testing or delivery — including transit, your storage, or reconstitution. Certificates are filed against the lot number on the vial; an unfiled lot reads PENDING rather than a stand-in number.

• COA library, filed by lot

No. We provide product specifications and storage information, but we cannot provide reconstitution protocols, concentrations, dosing, or administration guidance. Those decisions belong to the qualified researcher and depend entirely on the research application. Storage conditions for each compound are published on its product page and printed on the packaging.
