REFUND AND REPLACEMENT POLICY

We will replace an item, at our discretion and subject to verification, when the wrong item was shipped, the shipment arrived with documented transit damage, or the supplied item materially differs from the batch specification provided at purchase. Replacement is the exclusive remedy.

Contact us within 48 hours of recorded delivery. Include the order number, item and lot information, a clear description, and photographs of the shipping package, label, seal, and affected material. Preserve all packaging and keep the material stored according to its handling instructions while the review is pending.

Replacement is not available for opened or improperly stored material, normal appearance variation, protocol incompatibility, buyer handling error, carrier delays without material damage, incorrect address information, unauthorized reshipment, or use outside the Research Use Agreement.

We may request additional documentation or return of the unopened item where lawful. An approved replacement will be shipped to the original qualified buyer and address. If replacement is impossible, Aceso Labs may provide store credit or another limited remedy required by applicable law.
