I have to say -Pillreports isnt perfect but its a bloody good start. If your looking at a new version or color of an old pill then I would say tread very carefully. At best test them at home first, if your not testing take half or one - if your not feeling anything after an hour do not take more. IF your feeling unwell seek medical attention - you were at a party, your drink was 'spiked' etc (you did not take x substance).
