MYYCO follows all federal and local laws regarding the sale of our microscopy research cultures. Early-stage cultures of psilocybe cubensis and panaeolus species do not contain the illegal compounds psilocybin or psilocin. These compounds emerge in later fruiting stages if the culture is grown. We do not condone the growth of our early-stage cubensis or panaeolus cultures – they are sold legally for microscopy research (not growth) in accordance with all federal and local laws. All of our cultures 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.​
