I have to apologise - PMA will not not show up on the marquis test at all (Stupid mistake). I was inferring that a MDxx/MDx/Pma pill would give a positive reaction to the marquis as I have never seen a pure PMA pill before (the ones I have seen/taken) were a mixture.
PMA + MDMA mixture? I thought I read PMA and MDMA were often a very dangerous mix due to the hyperthermia. If MDMA & PMA are mixed together I would imagine it would be very deadly.
