here you go: How to Test and Report On Products UPDATED 12/01
one thing i would add is to start a journal now (before you get and start using your products) of your daily life. nothing too personal like a diary but just how people respond to you, your interactions, and even how you feel you portray yourself to others.
often times people will follow the testing procedure exactly and then say they can’t find a sweet spot, or don’t notice any effects. by starting a log, you have a baseline to compare to when analyzing your results. e.g. day 0: i’m afraid to talk to this person; day 10: i talk to this person all the time now and s/he seems to really listen to me. thus you can see how you’ve grown and how others have changed.
