Returns & Refunds

All sales are final. SiixLabs does not offer refunds. This includes a change of mind, ordering the wrong item, or deciding not to use what you bought. Placing an order means you accept this policy.

We do not refund for any of the following:

• Change of mind
• Reconstituted, opened, or mixed products
• Misuse or use that is not lawful laboratory research
• Improper storage after delivery
• Delay once a carrier has the package
• The Meal Plan, once the order is placed

If a sealed package is damaged in transit, we may replace that item one time. This is a replacement, not a refund. To ask, email siixlabss@gmail.com within 7 days of delivery with your order number and clear photos of the parcel, the damage, and the label. We decide whether the damage is verified. Without photo evidence, we will not replace the item.

Lost packages are handled with the carrier. A replacement is not automatic. This does not apply to the Meal Plan, because it is not shipped as a package.

Research products are for in vitro and laboratory research only. They are not for human or veterinary use. A refund is not available because a product was used, or because it was bought for a purpose these terms do not allow.

Email siixlabss@gmail.com with your order number. We can answer questions about an order. We cannot make an exception to the no-refund rule.
