Penis Envy (PE) is arguably the most famous and potent strain of Psilocybe cubensis. Named for its distinct, thick, and phallic appearance, it packs a serious punch.Why is PE So Potent?PE produces fewer spores, which forces the mushroom to concentrate its energy into producing higher levels of psilocybin and psilocin. Users often report that PE is 1.5 to 2 times stronger than a standard strain like Golden Teacher.Dosing WarningIf you are used to taking 2 grams of a standard strain, start with only 1 gram of Penis Envy. The visuals are intense, and the mental headspace can be overwhelmingly deep for the unprepared.
