The medium adult oral dose, according to Hofmann, is 4-8 mg of psilocybin. Thus, you can estimate doses from the mg/g psilocybin figures found in technical literature. Data for "% dry weight" is the same as centigrams per gram, so just multiply by 10 to get the mg/g figure. Whenever possible, dosages in both shrooms and grams of *FRESH* material have been given. As a rule of thumb, for dried shrooms multiply the dosage in SHROOMS by two. There is no reliable way of converting weight in grams from fresh to dry, mushrooms contain -approximately- 90% water (ie. 10 grams wet = 1 gram dry) but the figure varies from species to species. The amount of psilocybin varies very considerably from mushroom to mushroom, depending on factors like age, growing conditions, etc. The variation is up to 4x for mushrooms grown in controlled laboratory conditions, and as much as 10x for ones that are not! With a new batch, always start out low. When reading the data, remember that psilocybin is almost equal in strength to psilocin. On the other hand, baeocystin does not appear to very hallucinogenic, but it is rumored to account for some of the side effects.

Once the mushrooms are dry, place them into *airtight* containers and protect from light. Some psilophiles grind the mushrooms, if you do so, weight the outcome. It is very hard to tell how much of a dose there is if the mushrooms are dried and ground. Some mix the dried and chopped or ground mushrooms with honey. Be sure to use a brand that hardens once cooled. Place in refrigerator. Note that mushrooms containing only psilocybin keep their psychoactivity much longer than those containing psilocybin and psilocin or only the latter. Evidently the psilocin breaks up easily and needs refrigeration to be preserved. I have never had to preserve mushrooms over a year so I wouldn't know exactly, but if stored properly the mushrooms stay psychoactive for *at least* a year. Especially with strong, large mushrooms like Str. cubensis, grinding is the only way of calibrating doses. With for example Ps. semilanceata, statistics ensure that the sum of 40 mushrooms from a batch will be more or less the same no matter which 40 you pick, but if you're eating only two Str. cubensis caps things are different. Thus, dry, grind, mix and weigh the resulting powder. After a carefully weighed initial dose (which you'll have to guess, aim low), it's easy to measure out smaller or larger doses in the future.
