Our live liquid mushroom culture syringes are isolated biological samples nurtured, tested, and expanded here at Liquid Fungi. Each culture is guaranteed 100% contaminate free, or we will replace it at no cost to you. Every syringe contains a proven high-output isolated sub-strain for maximum yield and minimum incubation time. Every purchase includes a sterile individually packaged hypodermic needle for injecting substrate. Syringes are used by laboratories to easily transfer isolated biological samples between locations and mediums without risk of contamination. Culture syringes should never be used to inject humans or animals for any reason.
