I think ur thinkin of adrenochrome, which is a metabolite of epinephrine (Adrenaline) that is found in the adrenal gland. I'm not really sure if it works (though ive heard it does.), but i can tell you where the rumor came from. FEAR AND LOATHING IN LAS VEGAS. One thing i can tell ya for sure is; its not the strongest hallucinogen on earth. Btw, the other way of obtaining adrenochrome without raiding a fresh corpse, is by oxidizing epinephrine. Oh and one more little detail, adrenochrome is suspected as a possible cause or contributing factor to schizophrenia.
