Mystery Fatass Magic Mushrooms (Psilocybe Cubensis, Mystery Fatass) is an extremely rare strain we were able to source through an exclusive organic mushroom farmer. The history and origins of the Mystery Fatass strain is not very clear, but we do know it has been around for at least a few decades. This strain was discovered and circulated amongst the psychonauts community back in the early 90s. Communication amongst the community was spotty back than as it was the early days of the internet and the beginning of message boards such as shroomery.org.
