Yep same substance but you misunderstand my point.

The risk here is that street mushrooms usually are going to be LESS potent than people think. What happens now, is that people pull the random statistic out of thin air saying "well 3.5g is about 35mg psilocybin so 25mg is good for the study." In reality, this dosage might end up being much higher than many of the positive anecdotes about "eating an eighth". And again, there's a million horror stories that use that same 3.5g weight.

That's why its silly to compare pharma-grade psilocybin with anecdotal evidence of street mushroom potency.
