Logistics

Shipping

Dispatch times, packaging and what to do if a parcel goes missing.

Processing

Orders confirmed before 2:00 PM PT on a business day are packed and handed to the carrier the same day. Orders after the cutoff go out the next business day.

Transit

Domestic parcels typically arrive in two to five business days. Tracking is emailed at hand-off. International destinations are quoted individually and the recipient is responsible for import compliance.

Packaging

Everything ships in plain, unbranded outer packaging. Vials are cushioned and labelled with the lot number. Lyophilized material is stable in transit at ambient temperature.

Lost or damaged parcels

Report a transit problem within seven days of the delivery scan and we will open a carrier claim and arrange a replacement where the claim is upheld.
