Return & Refund Policy
Effective Date: July 1st, 2026.
This Return & Refund Policy applies to all purchases made through thestimuluslabs.com. By placing an order, you agree to the terms below.
1. All Sales Are Final
Our products are research compounds intended exclusively for laboratory research use, sold in single-use sealed vials. Because their integrity cannot be verified once a package has left our custody, all sales are final. We do not accept returns or issue refunds for change of mind, incorrect use, or because a product simply wasn’t what you expected — please confirm your order carefully before checkout.
The only exceptions to this are set out below: your order arrived damaged, defective, or incorrect; independent lab testing shows a batch doesn’t match its Certificate of Analysis; or your order never arrived at all.
2. Damaged, Defective, or Incorrect Orders
If your order arrives damaged, defective, or different from what you actually ordered, contact us at support@thestimuluslabs.com within 48 hours of delivery with your order number and photos of the item and packaging. Once verified, you choose whether we replace the affected item with the correct item, or issue a full refund — either at no cost to you.
3. Failed Lab Verification
Every batch we ship is quality-tested and issued a Certificate of Analysis (COA). If independent third-party lab testing on a batch you received shows results that don’t match the purity or identity stated on its COA, contact us at support@thestimuluslabs.com within 14 days of delivery with your order number and a copy of the independent test results. We may ask for the affected item back for our own verification.
Once we’ve confirmed the discrepancy, you choose whether we reship a replacement from a retested batch, or issue a full refund to your original payment method — either at no cost to you.
4. Order Cancellations
Orders can be cancelled or changed free of charge any time before they ship. Once an order has shipped, it can no longer be cancelled and falls under the Damaged/Defective/Incorrect terms above rather than a standard cancellation.
5. Lost or Undelivered Packages
If tracking shows your package as delivered but you haven’t received it, or if a package appears lost in transit, let us know within 7 days of the expected delivery date and we’ll work with the carrier and with you to resolve it, up to and including a reshipment or refund.
6. Non-Returnable Items
Once a product has shipped and been delivered as described, it is final sale. We do not accept returns of opened, used, or otherwise correctly-delivered products, in keeping with the research-use handling standards described in our Terms and Conditions.
7. Refunds
Approved refunds are sent back via Zelle to the same account you paid from, and typically post within 5–10 business days depending on your bank.
8. Contact Us
Questions about an order? Reach us at support@thestimuluslabs.com or through our Contact page, and we’ll get back to you within one business day.
