Return window
We accept return requests made within 30 days after delivery for products that remain unopened, sealed, undamaged, and in their original packaging.
Return eligibility
To qualify for a return, the product must be unopened, unused, in resalable condition, and accompanied by its original packaging. Opened, reconstituted, used, improperly stored, or altered research materials cannot be returned because their chain of custody and quality can no longer be verified.
Starting a return
- Email office@pepmediclabs.com with your order number, the item involved, and the reason for the request.
- Wait for return authorization and shipping instructions before sending any item.
- Package the authorized item securely and return it as instructed.
Customers are responsible for return-shipping costs unless PepMedic sent an incorrect item or confirms that the product arrived damaged or defective.
Damaged, defective, or incorrect items
Contact us within 48 hours after delivery and include clear photographs of the product, packaging, shipping label, and visible damage. After review, we may replace the affected item or issue an appropriate refund. Please retain all packaging until the review is complete.
Research outcomes and handling
We do not issue refunds or replacements based on subjective experimental outcomes. Requests involving an opened or reconstituted product may be denied when storage, handling, reconstitution materials, or laboratory conditions cannot be verified.
Refund processing
Authorized returns are inspected after receipt. Approved refunds are submitted to the original payment method within 5–7 business days. Your bank or card issuer may require additional time to post the credit. Original shipping charges are not refundable unless the return resulted from our error or a confirmed defect.
Non-returnable items
- Opened, reconstituted, or used products
- Products returned more than 30 days after delivery
- Items without their original sealed packaging
- Items damaged through improper storage or handling after delivery
- Items marked final sale, when clearly identified before purchase
