Refund & Return Policy.

Refund window: report any issue within 48 hours of delivery (or of the expected delivery date). Eligible issues — orders that arrive damaged, contain an incorrect item, or are confirmed missing after carrier review — are resolved with a refund, replacement, or store credit.

Due to the nature of laboratory research materials, returns are generally not accepted once an order has shipped.

Refunds, replacements, or store credits may be considered when an order arrives damaged, contains an incorrect item, or is confirmed missing after carrier review. Customers must contact support within 48 hours of delivery or the expected delivery date and provide the order number, tracking information, a description of the issue, and clear photos of packaging or contents where relevant.

Helix28 Labs will review each issue in good faith and determine an appropriate resolution based on the circumstances, carrier findings, and order history.
