All materials offered by Poet Labs are intended strictly for laboratory and research purposes and are labeled “For Research Use Only” and “Not for Human Consumption.” These designations are used to clearly distinguish research materials from products intended for human or animal use and to support compliance with applicable U.S. laws and regulations.

These labels are not intended to comment on the quality, purity, or characteristics of the materials. Rather, they communicate the intended purpose and regulatory status of products supplied by Poet Labs. As a research supplier, Poet Labs requires purchasers to understand and acknowledge these limitations before completing a purchase.

Poet Labs does not provide instructions, dosing information, administration guidance, or recommendations for human or animal use. Products are supplied solely for lawful laboratory, institutional, and investigational research. It is the purchaser’s responsibility to ensure that all materials are handled, stored, and used in accordance with applicable laws, regulations, safety requirements, and institutional protocols.

Once an order has shipped, we are unable to make changes to the shipping address or reroute the package.

If your tracking information shows that your package was delivered but you cannot locate it, please check around your property and with nearby neighbors. Carriers may leave packages in discreet locations or with a neighboring address for security reasons.

If the package remains missing, please complete the following steps before we can review a reshipment:

1. Contact your local carrier facility
   Contact your local post office or carrier facility. If possible, ask your delivery person to check their vehicle or facility for the package.
2. File a lost-package claim
   Submit a claim directly with the carrier. For USPS shipments, you can file a claim through their online claims system. The tracking email we sent you contains the information needed to submit your claim.
3. Send us your claim confirmation
   Once your claim has been filed, the carrier will provide a claim number or confirmation email. Forward the claim number or a screenshot of the confirmation to Poet Labs. Our shipping team will then review the claim and discuss the available reshipment options.
