Are freshly picked mushrooms stronger than dried ones?
Difficult to say. Growing conditions, age, and species can all affect the amounts of psilocybin and psilocin in mushrooms. Psilocin breaks down easily and doesn’t survive the drying process. Psilocybin is much hardier (it survived over 115 years in one tested sample). Psycho activity depends on the ratios of the two in the mushrooms, which varies from species to species.
