Ordering FAQs

Common questions about testing, shipping, and storage.

How is a pen different from a vial?
Pens arrive pre-filled in solution (3 mL), sealed and batch-labeled. Vials ship as lyophilized powder that is reconstituted in the lab.
How does quantity pricing work?
Buy more of the same pen and strength and pay less per pen: 2 pens save 10%, 3+ save 15%, 5+ save 20%. It applies automatically in your cart. Discount codes don't stack with it; you get whichever saves more.
How should this be stored?
Keep pens refrigerated and away from light on arrival, and follow standard laboratory handling guidelines.
Can I get the certificate of analysis?
Yes — a COA is available for every lot. Contact support with your batch number and we will send it over.
What is your return policy?
Unopened, sealed pens can be returned within 14 days of delivery. See our refund policy for details.
