The Penis Envy is the most popular, strange and potent Psilocybe cubensis mushroom known to man.
 
Penis Envy-type variants are popularly considered the most powerful strains of P. cubensis, and APE is considered the most powerful of the Penis Envy variants.  Its effects have been described in glowing terms as being very visual with a lot of euphoria and deep thoughts. However, P. cubensis in general is highly variable in its potency, and the effect of eating the mushrooms can vary, too, depending on both set and setting (the mindset and the surroundings of the user at the time).  
 
Once a person ingests it, however they ingest it, the effects might come on in anywhere from twenty to forty minutes, sometimes a little more—a delay that can make proper dosing a little tricky. The “trip” can last for up to six hours, though duration, too, is variable. “Flashbacks,” in which the effects suddenly reassert themselves long after the mushrooms have left the user’s system, are possible, and are either an advantage or a disadvantage, depending on one’s point of view.
