This Refund & Return Policy applies to purchases from The Optimized Human at https://optimizedhumanproject.com. It should be read with our Terms of Service. All products are sold strictly for laboratory research purposes only and are not intended for human or animal consumption.
Email [email protected] or use the contact form and include your order number, the items at issue, and a short description of the problem. If an item arrived damaged or is not what you ordered, please include clear photos of the packaging and the product. We may also ask for the batch or lot information shown on the vial or label.
If a product arrives damaged, is defective, or is not the item you ordered, tell us within 7 days of delivery. If we confirm the problem, we will, at our option, replace the item or refund the purchase price of the affected item (and, where we are responsible, the related outbound shipping you paid for that item). Do not use or further handle a damaged research product except as we reasonably request so we can evaluate the claim.
You may request a return of an unopened item within 30 days of delivery. To qualify, the item must be unused, in its original packaging, with seals intact, and in a condition we can restock. We may decline a return that does not meet those conditions, that was marked as non-returnable at sale, or that cannot be resold as a research product in its original condition.
Authorized unopened returns may be refunded to the original payment method after we inspect the returned item. Original shipping charges are not refundable on unopened returns.
Except for a confirmed damaged, defective, or incorrect shipment, we generally cannot accept returns of:
Because these are laboratory research materials, we do not accept returns that appear to have been opened for human or animal use, and a return request does not change the research-use-only terms of sale.
Authorized unopened returns are not subject to a restocking fee.
If the return is for a damaged, defective, or incorrect item that is our responsibility, we will pay for return shipping. Contact support first and we will send you a prepaid return label or reimburse your return shipping cost.
If you are returning an unopened item for another reason, you are responsible for paying return shipping.
Do not send a product back until we have confirmed the return and, if needed, given you a return address or instruction. The return mailing address is provided by support once a return is approved.
Approved refunds are issued to the original payment method used at Bankful hosted checkout, unless that is not possible, in which case we will arrange another reasonable method with you. After we receive and inspect a returned item, we will issue the refund within 5 to 10 business days.
Bankful or your card issuer may take additional time to post the credit.
If you need to cancel an order before it ships, contact us as soon as possible at [email protected]. We will always honor a cancellation request received before the order ships, and we will issue a full refund to the original payment method.
If an order has already been transferred to a carrier, it is treated as shipped and this policy’s return rules apply instead of a cancellation.
Checkout may offer optional shipping protection for an additional amount shown at checkout. If you purchase shipping protection, it covers loss or damage in transit. To file a claim, email [email protected] within 7 days of delivery, or within 7 days of the expected delivery date for a lost package, and include your order number and photos (for damage claims). For a covered claim, we will provide a replacement or a refund.
