Shipping Policy

We ship within the United States only. We do not ship internationally, and we cannot ship to freight forwarders.

Orders placed before 2pm EST on a business day are dispatched the same day. Orders placed after that, or at a weekend, are dispatched within 12–24 hours of the next business day.

Dispatch is when the parcel leaves us. Transit time is additional and depends on the carrier and destination — typically 2–5 business days.

Shipping is free on all US orders. It still appears as a selectable option at checkout; it is simply priced at $0.00.

A tracking number is emailed to you once the label is created. If you have not received tracking within two business days of ordering, check your spam folder and then contact support@cylixlab.com with your order number.

Material ships in discreet outer packaging with no indication of contents on the exterior. Lyophilised powders are stable at ambient temperature for the duration of normal transit.

If your order arrives damaged, contains the wrong item due to our error, or does not arrive at all, we will replace it or refund it in full.

Contact support@cylixlab.com within 7 days of the expected delivery date with your order number and, for damage, a photo of the packaging and contents as received.

Claims raised after 7 days may not be recoverable from the carrier, and we may not be able to honour them.

We ship to the address you enter at checkout. Please check it. If a parcel is returned to us as undeliverable because of an incorrect or incomplete address, we can reship it once you cover the reshipment cost, or refund the order less any shipping cost we incurred.
