Order processing
Orders may take up to two business days to process before shipment. We do not ship on weekends or holidays. Orders placed after 12:00 p.m. Eastern Time on Friday will begin processing the following Monday, unless that Monday is a holiday.
Processing time is separate from carrier transit time. During high-volume periods, severe weather, or other unusual circumstances, processing may take longer.
Destinations and rates
Available shipping destinations and methods are shown at checkout. Shipping charges, if any, are calculated before you submit your order. Eligible orders over $120 receive free standard shipping; taxes and discounts may affect whether an order meets the threshold.
We may decline or cancel shipment to a location when required by law, carrier rules, product restrictions, or operational limitations.
Delivery estimates
Any delivery date shown at checkout or provided after purchase is an estimate, not a guarantee. Carrier delays, weather, service interruptions, incorrect addresses, and destination-specific conditions may affect delivery.
Tracking
When tracking is available, we will send it to the email address associated with the order after the carrier accepts the package. Tracking can take time to update after a label is created.
Address accuracy and changes
Please review the recipient name and shipping address before placing your order. Contact Customer Support immediately if a correction is needed. We cannot guarantee changes after an order enters fulfillment and cannot redirect a package once it is in the carrier’s possession.
Additional shipping charges may apply when a package is returned because an address was incomplete, incorrect, or undeliverable.
Lost, stolen, or damaged packages
Contact us as soon as possible with your order number and a description of the issue. For damage claims, include clear photos of the external packaging, packing slip, and contents, and keep all packaging until the review is complete.
Package protection may be available at checkout for transit coverage. Carrier scans and claim requirements may affect the available resolution.
Return Policy
New, unopened vials in their original condition and packaging may be eligible for a full refund when a return is requested within 30 days of delivery. Opened, used, altered, damaged, or tampered-with products are not eligible for return unless the issue resulted from our error or the product arrived damaged.
To request a return, contact Customer Support with your order number, the item you wish to return, and the reason for the request. Please wait for return instructions before sending anything back. Returns sent without authorization or to an address not provided by Customer Support may not be accepted.
Customers are responsible for approved return shipping costs unless we sent the wrong item or made another order error. When the return results from our error, we will provide or reimburse the approved return shipping cost.
Approved refunds are issued after the returned item is received and inspected. Refunds are sent to the original payment method when practical. Original shipping charges are not refundable unless the return resulted from our error, and payment-provider processing times may affect when the credit appears.
