What if my package is damaged or missing?
State your reservations to the carrier on delivery, take photos of the parcel and the vials, then contact support with your order number (or a screenshot of the tracking for a parcel not received). We open an investigation with the carrier; what happens next depends on its findings. No returns are accepted: all sales are final.

Yes. Tested batches come with a certificate of analysis from the independent laboratory Janoshik, available on the product page and in the Analyses section, and verifiable directly with Janoshik using its key.
