Shipping Policy

We currently ship to U.S. addresses only.

Orders placed before 2:00 PM Eastern Time (ET), Monday through Friday, ship the same day via 2nd Day Air. Orders outside the cutoff are not guaranteed to ship the same day.

Orders shipping to a PO Box are delivered by USPS. UPS/FedEx do not deliver to PO Boxes, so USPS delivery timeframes apply to these orders.

Simple Peptide is not responsible for shipping delays caused by:

  • Weather
