Stargazer mushrooms were found in the foothills of the Andes Mountains, most notably around the Inca ruins at Machu Picchu. You’ll also likely read that Stargazers owe their popularity to Paul Stamets and J.S. Chilton, who first featured them in his book The Mushroom Cultivator in 1983. The latter claim, at least, is untrue. Stamets and Chilton write about several strains of cubensis, yet the strains are named by their place of origin: Amazonian, Ecuadorian, Matias Romero, Misantla, and Palenque.
The potency of Psilocybe cubensis strains—Stargazer included—predominantly depends on environmental and growth conditions. So, like all cubies, Stargazer samples can likely be quite potent; it doesn’t take a considerable amount of psilocybin to produce a strong and meaningful trip. As such, “start low, go slow” are common words of advice from experienced psychonauts.
