Replying to any order confirmation or tracking email reaches the same inbox, so there is no need to start a new thread. Include the order number if you have one; it is in the confirmation email and starts with "cs_".
What to email about
- Tracking that has not moved after two business days. Carrier scans are missed more often than parcels are, but we will look.
- A damaged vial or parcel. Photograph the parcel and vials before handling further and email within 72 hours of delivery; replacement is at no cost.
- The manufacturer's certificate for a lot you received. It is forwarded on request; third-party reports are already on the certificates page.
- A wrong item. Our error, our postage, full replacement.
- Stock questions: when something sold out comes back, or whether a size not listed can be ordered.
- Referral codes for a place you would like to send people from.
What we will not answer
Anything about dosing, administration or use in humans or animals. Every product on this site is supplied for laboratory research only, and we do not give guidance that would suggest otherwise. Questions about handling, storage, reconstitution and reading a certificate are welcome; most are already answered in the guides and the FAQ.
Where we are
Nashville, Tennessee. Orders are packed and posted from here Monday to Friday. We do not have a public counter and we do not ship internationally.
