Penis Envy (PE) is definitively the most potent Psilocybe cubensis strain. Penis Envy magic mushrooms are strong and hard hitting. Many people believe that the strain was first isolated by legendary mycologist and psychonaut Terrence McKenna. This strain grows very slow but the yields are large fruits, and mycologists suggest that its slow growth results in more time for psilocybin production. Its effects include vivid visual stimulation, intense feelings of euphoria, and deep introspection and philosophical thought. Expect deep shamanic experiences, vision quests and an intense mystical experience. Not recommended for first time users. This strain is powerful and expect a trans-formative experience.
