Refund Policy
Last updated 04 Oct 2026
Our money-back guarantee refunds the full product price for unopened returns, specification failures and our own shipping errors. Approved refunds go back to your original payment method, usually within 5–10 business days.
1. Money-Back Guarantee
We will refund you in full if:
- you request a return of an unopened product within 7 days of delivery and it arrives back sealed
- a peptide fails the identity, purity or peptide-content specifications on its certificate of analysis, confirmed by an independent ISO/IEC 17025-accredited laboratory and reported within 30 days of delivery
- we shipped the wrong item, an item was missing, or it arrived damaged, reported within 7 days of delivery
- the carrier confirms your package was lost in transit
The guarantee covers the condition and specifications of what we ship. It does not cover the results of your research.
2. What Is Refunded
| Situation | Product price | Shipping |
|---|---|---|
| Order cancelled before processing | Full refund | Refunded |
| Unopened return | Full refund | Original shipping not refunded; you pay return shipping |
| Specification failure | Full refund or replacement, plus testing cost up to $300 | All shipping refunded; prepaid return label |
| Wrong, missing or damaged item | Full refund or replacement | All shipping refunded; prepaid return label |
| Lost in transit (carrier confirmed) | Full refund or replacement | Refunded |
| Duplicate or incorrect charge | Full refund of the extra charge | Not applicable |
On free-shipping orders, nothing is deducted for shipping.
3. Cancellations
You can cancel for a full refund until your order is processed. Once it has shipped, use our Return Policy instead.
4. Timing and Method
- We approve or decline a refund within 3 business days of receiving your return, or of receiving your report for damage, missing items or specification failures.
- Refunds go to the original payment method only.
- Your bank or card issuer may take 5–10 business days to show the refund.
5. Not Eligible for a Refund
- opened products that meet their stated specifications
- products used, altered, tampered with or stored improperly
- packages lost or stolen after the carrier confirms delivery
- orders returned or undeliverable because of a wrong address, a refused delivery or a failed signature or ID check (refund minus shipping costs, at our discretion)
- products from orders associated with prohibited use, fraud or misrepresentation under our Terms and Conditions (orders we cancel before shipping are refunded in full)
6. Chargebacks
Please contact us before disputing a charge with your bank; we resolve most issues within a few business days. Disputes filed in bad faith may lead to account closure, and we may share order records with our payment processor.
7. Research Use Only
All peptide products are sold for in-vitro laboratory research only and are not for human or animal use. A refund request that indicates human or animal use is not eligible.
