All liquid culture orders are shipped via USPS Priority Mail for fast and reliable delivery. We process and ship orders Monday through Friday, and any order placed before 6:00 PM Pacific Time will ship the following business day. Please note that orders placed on Friday will be shipped the following Monday morning. Every package is prepared with care and shipped discreetly—there will be no reference to mushrooms, liquid cultures, or spores on the exterior. The return address is listed simply as CLC to ensure privacy.

We cannot ship research cultures to any address in the states of Idaho, Florida, or Georgia.
