Returns and Refund Policy
Effective date: October 19, 2026
Unopened items in their original condition may be returned within 30 days of delivery for a refund to the original payment method. Damaged, incorrect or missing items are handled separately and at no cost to you. Nothing in this policy limits rights that cannot lawfully be excluded.
What qualifies for a return
An item qualifies for a return when it is unopened, in its original condition and packaging, and we receive your request within 30 days of the delivery date shown by the carrier. Opened or used research materials cannot be returned unless they arrived damaged or we sent the wrong item; those cases are covered below.
For a change-of-mind return, return shipping is your responsibility. Use a tracked service so you keep a record of the shipment. Items must arrive in the condition in which they were sent; we may decline a refund, or refund only part of the price, for an item that is opened, damaged or incomplete when it arrives.
How to start a return
Email support@peptico.com with your order number, the item you want to return and the reason. We review eligibility and reply with the return address and shipping instructions. Use the address in that reply when arranging the return. Do not send materials back without instructions; the business contact address is not an automatic return authorization.
Once the return arrives and is checked, we confirm the refund by email. A return request alone does not confirm that a refund has been approved.
Damaged, incorrect or missing items
If a delivered order contains damaged goods, the wrong product or size, or fewer items than ordered, contact support@peptico.com within 30 days of delivery, even if the packaging has been opened. Include your order number, a description of the problem and clear photographs of the affected goods, outer packaging and shipping label when available. If the wrong item arrived, identify the item received. Keep the goods and packaging while we review the issue.
For a confirmed damaged, incorrect or omitted item, we provide a replacement or the missing item and cover the cost of shipping it. This applies whether or not you purchased Shipping Protection. If a return is necessary, we will provide instructions and cover reasonable return shipping for the confirmed issue. Do not send materials back without instructions.
If the covered item cannot be replaced, we will refund its purchase price and applicable tax. We will also refund the shipping charge attributable to goods we cannot replace; if the entire order is affected, that includes the original shipping charge. Late notice does not remove any remedy required by law.
Missing packages and Shipping Protection
Contact us as soon as you discover a missing package. We may request tracking information, address confirmation or other reasonable supporting details. If you purchased Shipping Protection and the loss or theft is approved after a quick review, we replace the affected goods and cover replacement shipping.
If a covered replacement is unavailable, we refund the affected goods and applicable tax, the shipping charge attributable to those goods, and the protection charge attributable to the unresolved covered loss. We do not pay twice for the same loss. Without Shipping Protection, we assist with the carrier investigation and assess the facts and applicable obligations; additional replacement is not automatically promised.
Cancellation and inability to fulfill
Email support@peptico.com immediately to request cancellation. An invoice order that has not been paid can be cancelled by email at any time before payment. We will cancel an order that has not entered fulfillment if we can stop it in time. Once dispatched, cancellation is not guaranteed, and the return process above applies instead. A completed cancellation is confirmed by us; sending a request alone does not confirm cancellation.
If we cancel or cannot accept a paid order, we refund the cancelled goods and applicable tax, plus any shipping or protection charges that will not be used. If shipment is delayed, we provide the required delay notice and cancellation/refund option. We do not retain payment for goods we will not supply.
Quality or description concerns
Contact us promptly if you believe the supplied item or its documentation differs materially from what was ordered or advertised. Include the product, any lot number and supporting information. We investigate this separately from change-of-mind returns. If we confirm a supplied item does not match its advertised identity, quantity or description at delivery, we will replace it without additional shipping cost, or refund the affected purchase price and applicable tax plus attributable shipping charges if a replacement is unavailable. Lack of a desired experimental result alone does not establish a product defect. Other remedies required by law remain available. Do not use or alter disputed material while awaiting instructions where doing so would prevent review.
How refunds are paid
We submit approved refunds within seven business days of approval, or sooner when required by law. For a returned item, approval follows receipt and inspection of the return. For cancellation or shipment-delay refunds required by applicable law, the deadline runs from when your right to the refund arises, not from our later approval. Refunds go to the original payment method where available; if that is impossible, we arrange a lawful alternative. We send confirmation after submission. The time before the credit appears depends on your bank or card provider. We do not require store credit instead of money owed or deduct a restocking fee from the remedies promised here.
