Jack Frost Magic Mushrooms are some of the biggest and best strains of Psilocybe cubensis available. They are a blend of already large, isolated strains like Albino Penis Envy (APE) and True Albino Teachers. Because of their potent genes Jack Frost hallucinogenic mushrooms have a distinct Penis Envy like appearance. It seems as if someone took a regular Penis Envy Shroom and bleached it but left the blue patches of Psilocybin.
