Tests won't actually tell you if there's piperazines in your pill, just whether or not there's MDMA which can be tricky when some pressers do MD+Pipe combos.
Not really true though matey - Marquis very rarely shows a MDxx reaction to a MDxx and a Piperazine mixed pill.
If your used to using Marquis you can quite easily spot when your working with piperazines.
