Returns

Draft — pending legal review. This page is placeholder legal content and has not yet been reviewed by outside counsel. It is not final legal copy.

Sealed vials

Unopened vials with the seal intact may be returned within 14 days of delivery. Contact the lab team before shipping anything back so a return reference can be issued.

Opened material

Opened or reconstituted vials cannot be accepted under any circumstances. Once a seal is broken the chain of custody and the storage history can no longer be verified, and the material cannot re-enter stock.

Analytical discrepancies

If independent analysis of a vial does not agree with the published certificate for that lot, we replace or refund in full, and the lot is pulled and re-assayed.

Send the lot number and your analytical data to the lab team. This is treated as a quality event, not a customer service matter.

Damage in transit

Report visible damage or a broken seal within 48 hours of delivery with photographs of the packaging and the vial.
