Shipping Method and Carriers
We ship domestically within the United States via USPS and UPS. Standard shipping options are calculated at checkout based on package weight and destination ZIP code. Once a label is generated, you will receive an email containing your tracking number.
Estimated Delivery
Standard domestic shipping typically arrives within three to seven (3–7) business days after dispatch. Expedited options are available at checkout. Estimated delivery times are provided by the carrier and are not guaranteed by Greatest Peptides.
Shipping Restrictions
We currently ship only to addresses within the fifty United States. We do not ship to P.O. boxes for certain product categories. We do not ship internationally at this time. We reserve the right to refuse shipment to any address.
Cold-Chain and Handling
All peptides ship as lyophilized (freeze-dried) powder and remain stable at room temperature during standard transit. Upon receipt, products should be stored according to the storage instructions on the label. Long-term storage at refrigerated or frozen temperatures is recommended.
Lost, Stolen, or Damaged Shipments
Title and risk of loss pass to you when the carrier accepts the package. If a shipment is lost, stolen, or arrives visibly damaged, contact us at support@greatestpeptides.com within seven (7) days of the delivery date shown by the carrier so we can open a claim. Photographs of damaged packaging and contents are required for damage claims.
Address Accuracy
You are responsible for providing a complete and accurate shipping address. We are not responsible for delays or non-delivery resulting from incorrect or incomplete address information. Address changes after a label has been generated may not be possible.
Discreet Packaging
All orders ship in plain, unmarked outer packaging. Return labels and customs information identify Greatest Peptides only as required by carrier rules.
