Our mushroom liquid culture is the product of years of genetic isolation and replication. Our liquid cultures are designed to be the most robust, resilient, and fastest iterations of each subspecies of mushroom. All of our liquid culture syringes are backed by our guarantee: if your syringe does not result in successful research or is contaminated, we will provide a free exchange or 100% full refund. Please note; all of our liquid culture syringes are sold for microscopy research, not growth. We cannot legally answer any questions regarding the growth of our cultures so please do not ask.
