text: Yo, we ran tests, check the methods we chose,
  High-performance liquid chromatography, that's how it goes.
  Electrochemical detection, we're on a mission,
  Measuring haloperidol and its alcohol metabolite concentration.
  
  In human post-mortem tissues, we went deep,
  Occipital cortex, where the secrets keep.
  Nine schizophrenic patients, treated with haloperidol,
  We found both the drug and its reduced form, yo.
  
  But in nontreated subjects, we found nothing at all,
  No haloperidol or reduced form, that's the call.
  Rats and mice in the lab, we gave 'em a dose,
  But even after ten days, reduced haloperidol didn't impose.
  
  The concentrations were below the assay's detection,
  This metabolite, hard to find, no reflection.
  In haloperidol-treated patients, yo, we saw a difference,
  Slightly higher concentrations, that's the evidence.
  
  But hold up, we ain't done, more research is needed,
  To understand the importance, biological, indeed it's heated.
  This haloperidol metabolite, we gotta explore,
  To find out what it means and what it has in store.
