1. Overview
This Return and Refund Policy governs all transactions made through Zest Peptides (“the Company”, “we”, “us”, “our”). By placing an order on our platform, you agree to the conditions outlined below. All products are supplied strictly for research purposes and handled under controlled laboratory supply standards.

2. Research Use Classification
All items provided by Zest Peptides are intended strictly for laboratory research use only. Products are not suitable for human or animal consumption, application, or therapeutic use. Due to the sensitive nature of research materials, returns are restricted and evaluated under strict compliance conditions.

3. General Return Policy
In most cases, all sales are final once an order has been processed and dispatched. Returns are not accepted for change of mind, incorrect ordering, or lack of understanding of product specifications. Customers are responsible for ensuring correct selection prior to purchase.

4. Eligible Return Cases
Returns or replacements may only be considered under limited circumstances, such as incorrect item shipment, verified manufacturing defect, or significant deviation from order specifications. Any such issue must be reported within a reasonable timeframe after delivery along with clear evidence for review.

5. Refund Eligibility
Refunds are not guaranteed and are issued only after internal verification confirms eligibility. Approved refunds may be processed in cases where replacement is not feasible or where a confirmed error has occurred on the Company’s part. Refunds, if approved, will be issued using the original payment method or an alternative approved method.

6. Non-Refundable Situations
Refunds will not be issued for misuse, improper handling, unauthorized application, or failure to follow research handling protocols. Products that have been opened, altered, contaminated, or used in any form are strictly non-refundable. Delays caused by customs, shipping carriers, or external factors do not qualify for refunds.

7. Reporting Issues
Customers must report any issues related to damaged, incorrect, or defective items promptly upon receipt. Requests must include order details, clear photographic evidence, and a description of the issue to facilitate proper evaluation.

8. Return Authorization Requirement
No returns will be accepted without prior written authorization from Zest Peptides. Unauthorized returns may be rejected or discarded without compensation. All return instructions must be followed exactly as provided by our support team.

9. Inspection and Verification Process
All returned items, where applicable, are subject to inspection and verification before any refund or replacement is approved. The Company reserves the right to determine eligibility based on internal quality control assessment.

10. Shipping Costs for Returns
Unless otherwise stated, customers are responsible for return shipping costs. Shipping fees are non-refundable. If a return is approved due to Company error, reasonable return shipping costs may be reviewed on a case-by-case basis.

11. Order Cancellation Policy
Orders may only be cancelled prior to processing or dispatch. Once an order has entered the fulfillment or shipping stage, cancellation is no longer possible.

12. Chargebacks and Payment Disputes
Any chargeback initiated without prior communication with the Company may result in account suspension and restriction of future access. We encourage customers to contact support to resolve disputes directly before initiating payment reversals.

13. Lost or Damaged Shipments
Claims related to lost or damaged shipments must be submitted within a reasonable timeframe after delivery confirmation or expected delivery date. Such cases will be reviewed individually, and resolution will depend on carrier investigation and internal verification.

14. Policy Limitations
Due to the specialized nature of research materials, flexibility in returns and refunds is limited. All customers acknowledge and accept these conditions prior to purchase.

15. Policy Updates
Zest Peptides reserves the right to modify or update this Return and Refund Policy at any time without prior notice. Continued use of the website constitutes acceptance of the revised policy.
