Returns Policy
Last updated: July 23, 2026
Overview
Because our products are sensitive research materials whose integrity cannot be verified once a vial ships, orders are all sales final. We cannot accept returns of opened, used, or unopened items for safety and integrity reasons. This policy explains the limited cases where we can help, including the one-hour window in which an order can still be cancelled.
Cancelling an order
You have one hour from the moment you place an order to cancel it. Email hello@steadfastresearchgroup.com with your order number within that hour and we will cancel the order and refund you in full, back to your original payment method.
After one hour the order has entered fulfillment — it is picked, packed, and labeled — and can no longer be cancelled. From that point the all-sales-final terms below apply, along with the damaged, defective, and incorrect-order protections.
Damaged or incorrect orders
If your order arrives damaged, defective, or incorrect, contact us within 7 days of delivery with your order number and photos. We will arrange a replacement or refund for the affected items at no cost to you.
Non-returnable items
- Opened, used, or reconstituted products.
- Unopened products returned for reasons other than damage, defect, or a shipping error.
- Items without original packaging or lot labeling.
How to start a claim
Email hello@steadfastresearchgroup.com with your order number and a description of the issue. Do not ship anything back until we confirm next steps.
Refunds
Approved refunds are issued to the original payment method within 5 to 10 business days after we process the claim. Shipping charges are non-refundable except where an order was damaged or incorrect.
