Dual Aminos — Return & Refund Policy
This Return & Refund Policy explains how Dual Aminos handles cancellations, returns, replacements, and refunds for research materials purchased through our Site. It supplements our Terms & Conditions and Shipping Policy.
1. All Sales Are Generally Final
Due to the sensitive and specialized nature of research peptides and related compounds, all sales are generally final. Once an order has been processed or shipped, it typically cannot be cancelled, returned, or refunded except in the limited circumstances described below.
2. Limited Exceptions
We may, in our sole discretion, consider a return, replacement, refund, or store credit when:
- Products arrive damaged or defective.
- Incorrect items were shipped due to our fulfillment error.
- A product is missing from a confirmed shipment due to our error.
We reserve the right to determine whether a refund, replacement, or store credit is appropriate after reviewing your request and supporting documentation.
3. How to Request a Review
To initiate a review, contact us at support@dualaminos.com within a reasonable time after delivery — typically within 7 days of delivery for damaged, defective, or incorrect items, and within 72 hours of delivery for shipping-related damage reported under our Shipping Policy.
Please include:
- Your order number
- Product name(s) and lot or batch number(s), if available
- A brief description of the issue
- Clear photos of the packaging, label, and product condition (when relevant)
We may request additional information to complete our review.
4. Items Not Eligible for Return
The following are not eligible for return or refund:
- Products that have been opened, used, reconstituted, or otherwise handled in a way that could compromise integrity
- Products that were improperly stored after delivery
- Orders refused, seized, delayed, or destroyed by carriers, customs, or other authorities
- Change-of-mind purchases, ordering errors by the customer, or dissatisfaction with research outcomes
- Products purchased under incorrect pricing that we cancelled and refunded under our Terms (handled separately as order cancellations)
5. Cancellations
Order cancellations may be requested before the order has been processed or shipped. Once an order has been processed or shipped, it cannot be cancelled. Contact support@dualaminos.com as soon as possible if you need to request a pre-shipment cancellation or modification.
6. Refund Method & Timing
If we approve a refund, it will generally be issued to the original payment method. Processing times vary by payment provider and financial institution. Store credit or product replacement may be offered instead of a monetary refund at our discretion.
7. Purity & Quality Concerns
If you believe a product does not meet stated research-grade specifications, contact us with your order details, lot information, and any independent analytical results you wish us to review. Dual Aminos will evaluate quality concerns in good faith; remedies, if any, are determined at our sole discretion and may include replacement or refund where appropriate.
