Because Down South Aminos supplies research-use-only compounds and laboratory materials, we cannot accept general returns once products have been shipped or delivered because storage conditions, handling conditions, and product integrity can no longer be independently verified.

Returns are not accepted for:

• Opened or used products.
• Products that have left controlled or verifiable storage conditions.
• Customer errors when selecting, ordering, or purchasing products.
• Changes of mind after an order has been fulfilled or shipped.
• Dissatisfaction based on perceived effects, performance, results, or personal expectations.
• Products that were improperly stored, handled, altered, or otherwise compromised after delivery.

These restrictions are necessary to preserve product integrity, maintain appropriate quality-control standards, and prevent returned laboratory materials from being placed back into inventory.

Down South Aminos may offer a replacement, account credit, or refund when a verified order issue falls within one of the following circumstances:

Incorrect Item Received

You received a different product from the product shown on your confirmed Down South Aminos order.

Product Damaged During Shipping

The product arrived broken, cracked, leaking, visibly compromised, or otherwise physically damaged during transportation.

Missing Items

One or more products listed on your confirmed order were not included in the delivered shipment.

Lost or Undelivered Packages

Claims involving shipments that are lost or remain undelivered may be reviewed on a case-by-case basis when tracking information and the applicable shipping carrier indicate that the package has been lost and cannot be successfully delivered.

To qualify for review, refund or replacement requests should generally be submitted within 7 days of delivery, or within 7 days of the date the carrier confirms a shipment as lost where applicable.

Refunds, credits, or replacements will generally not be issued in the following situations:

• Packages confirmed as successfully delivered by the shipping carrier.
• Packages lost, misplaced, or stolen after confirmed delivery.
• Products incorrectly selected or ordered by the customer.
• Products that have been opened, used, reconstituted, altered, damaged, or tampered with after delivery.
• Products showing evidence of improper storage or handling after delivery.
• Orders shipped to an incorrect or incomplete address supplied by the customer.
• Delivery delays caused by incorrect customer information, carrier disruptions, weather, customs, holidays, or circumstances outside the reasonable control of Down South Aminos.
• Dissatisfaction based on expected outcomes, effects, performance, or results. Down South Aminos products are supplied strictly for research purposes.

To request review of an eligible refund, replacement, missing-item claim, or damaged-order issue, contact Down South Aminos using the information below.

Please include the following information:

1. Your full name or institution name.

3. The email address associated with your order.

Down South Aminos aims to review refund and replacement requests as promptly as reasonably possible. Additional information may be requested before a claim can be approved.

• Original shipping charges are generally non-refundable.
• If a replacement is approved because of a verified Down South Aminos fulfillment error or qualifying shipping damage, Down South Aminos may cover reasonable shipping costs associated with sending the approved replacement.
• Additional shipping costs resulting from an incorrect address or other incorrect information supplied by the customer may remain the customer's responsibility.

Maintaining the integrity of laboratory and research materials requires appropriate storage, transportation, and handling. Once an order leaves our controlled fulfillment environment, Down South Aminos cannot independently verify every environmental or handling condition during transportation or after delivery.

For this reason, opened, used, altered, compromised, improperly handled, or temperature-sensitive products cannot generally be returned once their storage or product integrity can no longer be verified.

This policy helps Down South Aminos maintain rigorous quality-control, inventory-management, and research-material handling standards.

If you need to cancel an order, contact Down South Aminos at support@downsouthaminos.com as soon as possible.

Cancellation requests are not guaranteed. Once an order has entered processing, fulfillment, or shipment, it may no longer be possible to cancel or modify the order.

If a refund is approved, it will generally be issued through an available method determined by Down South Aminos and the payment method originally used for the transaction.

Processing times may vary depending on the payment provider, financial institution, transaction method, or other circumstances outside the control of Down South Aminos.

Down South Aminos reserves the right to modify, update, or replace this Refund & Returns Policy when reasonably necessary to reflect changes in our operations, products, fulfillment procedures, shipping procedures, product-handling requirements, payment processes, or website policies.

The most current version of this policy will be published on downsouthaminos.com together with an updated revision date.
