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.

• Double-check your shipping address during checkout.
• We are not responsible for delivery issues due to incorrect or incomplete addresses.

Simple Peptide is not responsible for shipping delays caused by:

• Weather
• Carrier issues
• Other factors beyond our control

• If tracking shows your package as delivered but not received, contact the carrier.
• We are happy to assist with filing a claim but are not liable for lost or stolen packages after delivery is confirmed.

In the event of a shipping related issue (such as delay, misdelivery, or loss) Simple Peptide can reship your package 7 business days after the original scheduled delivery date, and once we receive confirmation from the shipping carrier regarding the status of your original order. We appreciate your understanding as we work with our shipping partners to ensure your order arrives as quickly and securely as possible.
