Refund & Return Policy

Last Updated: September 22, 2026

At Azyven Research LLC (“Azyven Research,” “we,” “us,” or “our”), product quality, order accuracy, and product integrity are important to us.

Because storage, handling, and chain of custody can affect the integrity of research materials, our return policy differs from that of ordinary consumer merchandise.

Research Materials — Final Sale After Shipment

All sales of research materials are final once the order has shipped, except for damaged, defective, incorrect, lost, or otherwise qualifying order issues, or where a return, refund, replacement, or other remedy is required by applicable law.

Research materials cannot be returned to inventory or resold after they have left our controlled fulfillment process because Azyven Research cannot verify the storage, handling, environmental conditions, or chain of custody of a product after shipment.

For these reasons, we do not accept ordinary returns or exchanges of research materials after shipment.

Damaged, Defective, or Incorrect Orders

If you receive an item that is damaged, defective, or different from the item you ordered, please contact Azyven Research promptly after delivery.

Please provide, when applicable:

Your order number
A description of the issue
Photographs of the product
Photographs of the shipping package and packaging materials
The shipping label or tracking information
Any other information reasonably necessary to evaluate the claim

Please retain the affected product, shipping container, packaging materials, and shipping label until we have completed our review.

After reviewing the circumstances, an appropriate resolution may include replacement, refund, store credit when agreed upon or appropriate, or another remedy consistent with applicable law.

Missing or Lost Orders

If an order has not arrived, tracking has stopped updating for an unusual period, or you believe a shipment has been lost, please contact Azyven Research promptly with your order number and tracking information.

We may work with the applicable shipping carrier or fulfillment provider to investigate the shipment.

If an order is determined to be lost or otherwise qualifies for a remedy, Azyven Research will provide an appropriate resolution in accordance with this policy, our Shipping & Delivery Policy, and applicable law.

Packages Marked Delivered but Not Received

If tracking shows that a package was delivered but you cannot locate it, please first check the delivery location, household or business recipients, nearby areas where the carrier may have placed the package, and any delivery information provided by the carrier.

You should also contact the carrier when appropriate.

If the package still cannot be located, contact Azyven Research promptly so we can review the circumstances.

A carrier's delivery confirmation may be considered evidence of delivery, but reported delivery issues will be evaluated based on the available information and circumstances.

Order Cancellations

If you need to cancel an order, contact Azyven Research as soon as possible.

We will make reasonable efforts to accommodate cancellation requests received before fulfillment begins.

Once an order has been processed, packaged, submitted for fulfillment, or shipped, cancellation may no longer be possible.

If an order is properly cancelled before shipment after payment has been collected, the applicable amount will be refunded in accordance with this policy and applicable law.

Change-of-Mind and Customer-Error Returns

Azyven Research does not accept returns or exchanges of research materials after shipment based solely on:

Change of mind
Ordering the wrong product or strength
No longer needing the product
Failure to review the order before purchase
Other circumstances unrelated to an error by Azyven Research or a qualifying problem with the order

Please review product selection, strength, quantity, shipping address, and other order information carefully before completing checkout.

Refund Processing

When a refund is approved, it will generally be issued to the original payment method unless another method is required by law or agreed upon where appropriate.

Processing time after Azyven Research issues a refund may depend on the customer's bank, card issuer, or payment provider.

Original shipping charges may be non-refundable when the refund results from customer error, cancellation, refusal of delivery, or another circumstance not attributable to Azyven Research, except where otherwise required by law.

When a refund results from an error by Azyven Research or another qualifying circumstance, applicable shipping charges will be handled in accordance with the circumstances and applicable law.

Unauthorized Returns

Do not return products to Azyven Research without prior authorization.

Because research materials cannot ordinarily be returned to inventory after shipment, sending a product back without authorization does not guarantee eligibility for a refund, replacement, exchange, or credit.

Contact Azyven Research before attempting to return any product.

Refused and Undeliverable Shipments

If a shipment is refused or returned as undeliverable because of an incorrect or incomplete customer-provided address, unsuccessful delivery attempts, refusal of a valid shipment, or another circumstance attributable to the recipient, the order may remain subject to our final-sale policy.

Where reshipment is available, additional shipping charges may apply.

Azyven Research will review returned or undeliverable shipments based on the circumstances and applicable law.

Shipping Issues

Shipping-related claims are also subject to our Shipping & Delivery Policy.

That policy contains additional information concerning carrier delays, damaged shipments, tracking, delivery confirmation, multiple shipments, and undeliverable packages.

Research Use Only

Products sold by Azyven Research are intended strictly for legitimate laboratory and scientific research purposes and are not intended for human or veterinary use.

Please review our Research Use Only & Compliance Policy for additional information regarding product-use restrictions and purchaser responsibilities.

Policy Abuse and Fraud

Azyven Research reserves the right to investigate claims and to refuse fraudulent, abusive, materially misleading, or duplicative refund or replacement requests to the extent permitted by applicable law.

Nothing in this provision limits legitimate customer rights or remedies.

Our Commitment

Our goal is to address legitimate order problems fairly and promptly while maintaining the product-integrity and chain-of-custody standards appropriate for research materials.

Nothing in this policy limits any rights or remedies that cannot legally be waived under applicable law.
