Common questions
Where is my order?+
Every order gets a tracking link by email when it ships. Your orders page shows live status for each one. Orders placed before 2:00 PM ET on a business day dispatch the same day from Dover, NJ.
How do I return something?+
Open the delivered order and choose Start a return. Sealed, unopened vials can be returned within 14 days. Store-credit refunds post as soon as the return is approved; card refunds take up to 14 days to appear.
How do I find the report for my vial?+
Scan the QR code on the vial, or enter its printed lot code on the Verify your vial page. The report shown is the one published for that specific lot — nothing is inferred.
Can I change or cancel an order after placing it?+
Yes, until it dispatches. Email us the order number and we'll catch it if it hasn't shipped. Once a tracking number exists, handle it as a return instead.
Do you ship outside the US?+
Shipping restrictions apply by destination and material. Ask before ordering and we'll confirm whether we can ship to you.
How long do replies take?+
One business day, Monday to Friday. Questions that need a compliance review can take one additional day.
