1 Shipping Rates

Free standard shipping on all orders of $99.00 or more (merchandise subtotal before tax). Free shipping is applied automatically at checkout.

Orders under $99.00 ship at a flat rate of $9.99 for FedEx standard shipping within the United States.

Customers who qualify for free standard shipping may upgrade to a faster FedEx method at checkout and pay only the difference.

2 Shipping Methods and Delivery Estimates

All orders ship via FedEx only. Delivery estimates start on the ship date, not the order date. Times are FedEx estimates and are not guaranteed by Certified Pep Lab.

Actual delivery can vary with destination, weather, carrier volume, and other factors outside our control.

3 Order Processing

Orders placed on business days before 2:00 PM Eastern Time are typically processed and handed to the carrier the same day. Orders placed after that cutoff, or on weekends and U.S. federal holidays, ship the next business day.

Processing includes payment review, quality check, and packaging. Additional verification is occasionally required and may add one business day.

4 Destinations

We currently ship to addresses in the United States, including all 50 states and U.S. territories. We do not offer international shipping at this time.

We ship to residential and commercial street addresses only. FedEx does not deliver to P.O. Boxes. A physical street address is required at checkout.

5 Tracking

When your order ships you will receive a confirmation email with your FedEx tracking number. Track the shipment at fedex.com or in the FedEx app. Tracking can take up to one business day to appear after the confirmation email. If tracking has not updated after two business days, contact us.

6 Packaging

Products are packed to protect integrity in transit, with appropriate cushioning and, when needed, insulation. Outer packaging does not display product names or research descriptions.

7 Address Accuracy

You are responsible for a complete and accurate shipping address at checkout. Certified Pep Lab is not responsible for delivery to an address you provided incorrectly. If a shipment is returned because of a bad address, we will contact you about reshipment; additional shipping charges may apply.

Address changes can be made only before the order has shipped. Contact us immediately if you need to update an address.

8 Delivery Issues

Lost packages. If FedEx tracking shows no movement for more than seven business days, contact us. We will work with FedEx to locate the package or arrange a replacement when the loss is confirmed in transit.

Damaged packages. Photograph the outer packaging and the product and send the photos to us within 72 hours of delivery. Verified damaged items are replaced at no extra cost. See Returns below.

Stolen or missing after “Delivered.” Once FedEx marks a package delivered, we are not responsible for theft or removal from the delivery location. Use a secure drop point. File a report with FedEx and local law enforcement, then contact us so we can share shipment records.

9 Signature Requirement

Orders over $200 may require a signature at delivery at our discretion. You will be notified if a signature is required.

10 Backorders

If an item is temporarily out of stock, that status is shown on the product page, in the cart, and at checkout. Completing a purchase of a backordered item means you accept that it will ship when available.

If a backordered item is not available within 14 days of the order date, we will email you. You may choose a partial shipment with a refund for the unavailable item, or cancel the full order for a refund. If we do not hear back within seven days, we may cancel the backordered item, refund it, and ship any in-stock items.

Refunds go to the original payment method, typically within 5–10 business days of confirmation.

11 Cancellations

You may cancel an order only before it has been processed for shipping. Once a tracking number is created, the order cannot be cancelled.

12 Returns, Refunds, and Replacements

Research peptides and related laboratory materials are temperature- and chain-of-custody sensitive. We cannot verify storage conditions after a product leaves our facility, and we cannot restock opened or returned research materials for other laboratories.

Damaged or incorrect items. If your order arrives damaged (for example, a broken vial) or you received the wrong item, notify us within 72 hours of delivery. Include your order number and clear photographs of the damage or error. Verified damaged or incorrect items will be replaced at no additional cost. We do not offer refunds in place of replacement except where we cannot replace the item.

We do not accept returns for change of mind, unused product, or buyer’s remorse.

13 Chargebacks and Disputes

If there is a problem with your order, an unrecognized charge, a missing or damaged shipment, or a product that does not match its documentation, contact Certified Pep Lab before opening a dispute with your bank. We respond within one business day and resolve legitimate issues under this policy, including replacement or refund where warranted.

Unauthorized or fraudulent charges are investigated promptly; confirmed fraud is refunded in full. Chargebacks filed without first contacting us are contested with order records, delivery confirmation, and the acknowledgments made at checkout. Filing a chargeback on a delivered, as-described order may result in closure of the associated account.
