Refund Policy

An order is not accepted until payment has been received and matched to it. Orders awaiting payment are held for a limited period, which is stated on your order page and in your order emails.

If payment is not received within that period, the order is automatically cancelled and the items return to stock. No charge is made and nothing further is owed. You are welcome to place a new order at any time.

If you need to cancel an unpaid order before that period ends, contact us and we will cancel it for you.

Because research compounds, peptides, and chemical reagents require controlled storage conditions to preserve chemical stability, all sales are final once payment has been received.

Once a paid order enters our processing pipeline it cannot be altered or modified. If you contact us before an order has been dispatched we will do what we reasonably can, but we cannot guarantee a change or cancellation at that stage.

To maintain chain-of-custody security and regulatory compliance, Prime Core Dynamics does not accept returns or exchanges. Once a package leaves our facility we cannot verify its storage conditions or temperature controls, so items cannot be returned to inventory.

Refunds or store credits will not be issued for:

• Change of mind, buyer's remorse, or mistaken orders.
• Refused or abandoned deliveries.
• Incorrect shipping addresses provided by the customer at checkout.
• Claims arising from improper handling, storage, or non-laboratory application.

Where we have made a verified error, Section 4 applies. Where a refund is issued at our discretion, it is returned by the same method the payment was made.

We take full responsibility for internal packing errors or transit damage that occurs prior to confirmed delivery. If you receive an incorrect item, a missing item, or a product damaged in transit, you must notify Prime Core Dynamics in writing within seven (7) calendar days of the carrier's confirmed delivery date.

Requests submitted after the 7-day window will be denied without exception.

Mandatory unboxing verification. To prevent fraudulent claims and ensure accurate resolution, all claims for shipping damage or missing items must include the following unedited documentation:

• Unboxing video. A clear, unbroken recording starting from the sealed package, showing the shipping label, the box being opened, and all enclosed contents being inspected.
• Packaging photos. Clear photos of the outer shipping box showing any external damage, and of the shipping label.
• Contents and packing slip. High-resolution photos of all items received alongside the enclosed packing slip.

Claims submitted without complete video and photographic evidence will be automatically denied.

Upon verification of an eligible fulfillment error caused by Prime Core Dynamics, we will, at our sole discretion, dispatch a replacement for the affected items. Cash refunds are not guaranteed.

Once a carrier marks a shipment as "Delivered" through tracking or delivery confirmation, ownership and risk of loss transfer entirely to the buyer.

• Prime Core Dynamics is not responsible for packages that are stolen, misplaced, or damaged after delivery, including theft from mailrooms, porches, front desks, or delivery lockers.
• Refunds, credits, or replacements will not be issued for carrier-confirmed delivered packages.

Any chargeback or payment dispute filed for an order marked as "Delivered" by the carrier, or initiated to circumvent our refund, cancellation, or Research Use Only policies, will be vigorously disputed.

We use carrier delivery records, tracking data, access logs, and your agreement to these terms at checkout to dispute such claims. Customers who initiate fraudulent or policy-violating chargebacks will have their accounts permanently terminated and will be barred from future orders with Prime Core Dynamics.

By placing an order with Prime Core Dynamics, you certify that you have read, understood, and agreed to this Cancellations, Returns and Refunds Policy, and acknowledge that all products purchased are strictly intended for in vitro laboratory research purposes only.
