Refund & Return Policy
This policy explains when returns are accepted, how refunds are processed, and how we handle discrepancies, damaged, or incorrect orders.
For safety and integrity reasons, only sealed, unopened lots are eligible for return. Opened or reconstituted materials cannot be accepted back once dispatched.
Unopened Materials
Sealed, unopened lots may be returned within 14 days of delivery for a refund, provided the packaging and seal are intact. For safety and integrity reasons, opened, reconstituted, or otherwise used materials cannot be returned.
How to Request a Return
Contact us at info@grindlabresearch.com with your order number and reason for return. We will issue a returns authorisation and address before you send anything back. Return shipping costs are the responsibility of the buyer unless the return is due to our error (see Discrepancies below).
Refund Timing
Once we receive and inspect the returned item, refunds are processed within 5–10 working days to your original payment method. You'll receive an email confirmation once the refund has been issued.
Discrepancies and Defective Items
If a lot does not match its published Certificate of Analysis, arrives damaged, or the wrong item was sent, contact us with the lot number and photographs where relevant. In these cases we cover return shipping and will offer a replacement or full refund at your choice.
Non-Returnable Items
- Opened or reconstituted materials
- Items without their original lot packaging or labelling
- Returns reported outside the 14-day window
