From what I'm reading, there are 5-20mg of psilocybin in a gram of mushrooms. So the 10mg and 25mg doses from the study are around 1-2 grams worth of mushrooms. The average recreational dose (in my experience) is usually between 1.75 and 7 grams (so anywhere from 10-140mg). But potency varies significantly in real world scenarios.
