Blue Meanies contains a vast amount of psilocybin, even in comparison with other mushroom strains. One of the things that makes Blue Meanies so good is its concentration of tryptamine alkaloids. These compounds provide a more intense psychedelic experience thanks to extremely high levels of psilocin and psilocybin.
Its high potency is one of two reasons why this mushroom bears this name. The other reason is the blue bruising spots on the stalk. However, these bruises are also a sign of its increased potency. A regular psychedelic trip on Blue Meanies lasts about 4-8 depending on the quantity ingested and your tolerance.
