Shipping Policy

Orders received before 4:00 PM CT Monday–Friday are processed the same business day. Orders received after 4:00 PM CT, on weekends, or on holidays are processed the next business day. Every order is reviewed for researcher verification and compliance before fulfillment.

We ship using major US carriers. Available carriers and service levels are shown at checkout with live rates based on the destination and package. A tracking number is emailed to you and displayed in your account once the label is generated.

Frontier Amino Labs ships exclusively to verified research addresses within the United States. We do not ship internationally or to PO boxes. We reserve the right to refuse shipment to any address that cannot be verified as a legitimate research facility, institution, or qualified researcher location. Orders to states with additional restrictions on research peptides may be cancelled and refunded at our discretion.

Shipping rates are calculated at checkout based on your selected carrier and service level. Shipping costs are non-refundable except where we determine the shipment was lost or damaged in transit. Shipping charges apply per order, not per item.

Products ship at ambient temperature and are packaged to protect against light, moisture, and physical damage during transit. Once a package leaves our facility, chain of custody can no longer be guaranteed — returned inventory cannot be restocked or resold.

A tracking number is provided for every shipment. You will receive a shipment confirmation email with tracking when your order is dispatched, and the tracking link is available in the Order History section of your account. If a shipment is marked delivered but not received, notify us within 7 days of the last tracking update so we can open a carrier investigation.
