[top]Introduction to Psilocybin

Psilocybin is the phosphate ester of psilocin. It is one of the psychoactive chemicals present in mushrooms from a multitude of genera, most notably Psilocybe (along with psilocin, baeocystin and norbaeocystin), collectively referred to as Magic Mushrooms. Psilocybin is metabolized in the body to psilocin.

LD50 (mg/kg) [2] :
Mice : 285 intravenously
Rat : 280 intravenously
Rabbit : 12.5 intravenously

[top]Chemistry of Psilocybin

Systematic (IUPAC) name:[3-(2-Dimethylaminoethyl)-1H-indol-4-yl] dihydrogen phosphate
Synonyms:3-[2-(Dimethylamino)ethyl]-1H-indol-4-ol 4-(dihydrogen phosphate), O-phosphoryl-4-hydroxy-N,N-dimethyltryptamine, Indocybin
Molecular Formula:C12H17N2O4P
Molar mass:284.25 g/mol [1]
CAS Registry Number:520-52-5
Melting Point:220-228C (crystals from boiling water)[2], 185-195C (crystals from boiling methanol)[2]
Boiling Point:no data
Flash Point:no data
Solubility:soluble in 20 parts boiling water, 120 parts boiling methanol; slightly soluble in ethanol; practically insoluble in chloroform, benzene[2]; slightly soluble in ether, acetone; insoluble in hexane[3]
Additionnal data:pH 5.2 in 50 % aqueous ethanol[2]
Notes:crystallized from water or methanol[2]

The LD50 of psilocybin is 280 milligrams per kilogram (mg/kg), and approximately 12.5 mg/kg when administered intravenously in rabbits.

Considering the average Psilocybe cubensis is 1% psilocybin by weight it would take 37lbs (17kg) of fresh mushrooms, or 1.3lbs (1.7kg) of dry mushrooms for a 130 lb (60kg) adult to reach the LD50.
