Penis Envy was developed by the famous entheogenic mycologist/enthobotanist and psilonaut Terence McKenna. Besides his wonderful teachings he left behind to fuel our thoughts and imagination, he also left one of the most unique and powerful cubensis mushrooms we have every experienced. Its nick named Penis Envy because they resemble.....well......you guessed it.. a penis. Terence was big on mushrooms and marijuana and he talks a lot of psilocybin mushrooms being a "male" energy and mj being a "female" energy. No wonder he developed a mushroom that looks like a penis.
