Refund & Return Policy
Last updated August 2026
Every order is protected against damage in transit. Because these are research chemicals whose integrity cannot be verified once they leave our control, claims are settled by replacement rather than by return of the goods.
What is covered
A one-time replacement is provided for products damaged in transit, incorrect items, and mislabelled items, where the claim is reported within 14 days of delivery and includes photographs of the product and the outer packaging.
One replacement per customer per order. All claims are subject to review and may be declined where the evidence is insufficient.
What is not covered
Change of mind, dissatisfaction, and any reason other than documented damage, an incorrect item, or a mislabelled item. Reconstituted or opened vials, products stored outside the conditions stated on the label after delivery, claims without photographic evidence, claims made more than 14 days after delivery, and orders without proof of purchase are not eligible.
How to make a claim
Submit a claim at nytrogene.com/returns with your order number and photographs, or email admin@nytrogene.com with the same. Claims are reviewed within one to two business days, and approved replacements are dispatched within one business day of approval.
Returning goods
Claims are settled by replacement, so there is normally nothing to send back. Do not return any product unless NytroGene asks you to. Where a return is requested, the address is NytroGene, PO Box 2116, Dearborn, MI 48123, United States.
Refunds
Where a refund is issued in place of a replacement, it is processed to the original payment method. NytroGene does not offer refunds for change of mind or dissatisfaction.
