I have never ate a shroom that came from cardboard but I do know that substrate doesnt effect potency  genetics do.  so if that was from a spore syringe potency is unknown but should still do the job.

Not true at all.


From Psilocybin Mushrooms of the World by Paul Stamets:

"Adding to the difficulty of ascertaining precise dosages is research byBeug and Bigwood (1982) which found a fourfold difference in the psilocybin content from mushrooms grown on rye grain, and nearly a tenfold difference in specimens collected in the wild.

Gartz (1989) found that raising tryptamine concentrations of cow dung and rice media by 25 millimolars directly affected the potency of Psilocybe cubensis mycelia, specifically in psilocin content: from .09% to 3.3% of dried mass. (Psilocybin content was actually depressed, but not nearly on the same order of magnitude.) This discovery may well explain why certain strains of P. cubensis are more potent than others when the diets of cattle are supplemented with nutrient-rich feed.

Jochen Gartz (1989) also made the interesting observation in the culturing of P. azurescens and P. cubensis mycelium that the raising of malt sugars to more than 10% resulted in the complete suppression of psilocybin production.

These two observations, one with tryptamines and the other with (carbon rich) sugars, underscore that the nutritional content of the substrate significantly affects potency."
