Questions, answered.
What does research use only mean?
Vivora pens are sold for laboratory research, such as stability, formulation and delivery-device studies. They are not medicines and are not for human or animal consumption. By ordering, you confirm you are 18 or over and buying for research. See the research use policy.
Where can I find batch reports?
See lab reports or the relevant product page for the current status. Where a report is available, match its sample and batch details to your packaging and check the named laboratory and methods. A pending report is not a confirmed test result.
What's in each box?
One pre-filled research pen, or two for GLOW and NAD+, in a window box printed with its batch code and closed with a numbered tamper seal.
How do I know my pen is genuine?
Check the packaging and printed batch number, then look for its published report. Contact Vivora using the details on our contact page if anything needs checking.
How do I pay?
By bank payment through Fena at checkout. You approve the payment in your own banking app, and we never see your bank details.
When will my order arrive?
Orders paid before 3pm (UK time) on a working day are dispatched the same day, tracked and signed for. UK delivery is usually the next working day. You can follow it on the tracking page. Full details are in the shipping policy.
How should pens be stored?
Follow the storage conditions printed on the box, and keep pens sealed in their box until they're used in your research.
Can I return an order?
Unopened boxes with the seal intact can be returned within 7 days of delivery. If something arrives damaged or wrong, message us within 48 hours. See the refund policy.
Do you supply labs in bulk?
See the wholesale page to enquire about quantities and current terms.
