Money doesn’t grow on trees, which means that more often than not we can sometimes find ourselves needing an extra bit of cash to get by.  Some people might opt for tapping a line of credit, some choose to borrow money from family and some might choose a more questionable source: becoming human research subjects.  Those considering this route would be best advised to pick up Guinea Pig Zero: An Anthology of the Journal for Human Research Subjects.  This book is a compilation of the zine put out by test subjects some years back.  Here they share stories, eschew warnings and rate various clinics which should help you make a more informed decision.
