Refund & Return
Last Updated: October 2026
Research peptides are sterile, single-use laboratory materials, so we cannot accept returns of shipped product. Instead of a general return window, we stand behind three specific things: that you receive your order, that it arrives intact and correct, and that it matches its published test results.
1. What we guarantee
- Lost in transit: if the carrier confirms your package was lost, or tracking shows delivered and you did not receive it, we reship free of charge.
- Damaged or incorrect item: report it within 48 hours of delivery with your order number, a description and clear photos, and we send a replacement at no cost. If a replacement is not available, you may choose store credit or a refund for that item.
- Identity or purity failure: if an independent lab test of an unopened vial from your order shows the compound does not match its labeled identity or falls materially below the purity on the published Janoshik report for that batch, we refund the item in full or replace it, your choice. We do not require the vial back. Send us the lab report and we will also publish it.
2. What we cannot refund
- Change of mind, or ordering the wrong product or size.
- Opened, reconstituted or used vials, except under the identity/purity guarantee above.
- Products damaged by improper handling or storage after delivery.
- Delays caused by the carrier once the package is in transit.
3. How to make a claim
Email support@delixlabs.com with your order number and the details above. We reply within one business day and resolve most claims within two. Refunds are returned to the original payment method and typically appear within 5–10 business days depending on your bank.
4. Cancellations
Orders can be cancelled for a full refund any time before they ship. Because most orders ship the same day, email us as soon as possible if you need to cancel.
5. Research use
All products sold by DelixLabs are for in-vitro laboratory research only and are not for human or veterinary use. Nothing in this policy changes that.
