I have heard that for many of the testers the detection of MDMA overrides the detection of PMA.
There may be many pills that have both in them.
What can I do to just test for PMA?
The darker reaction with mdxa will overide any other color, so with a single step test you'll get nowhere. fortunately PMA is a primary amine and mdma a secondary amine. by screening with EZ Test Xtreme you'll find out whether your pill contains a mixture. check: www.eztest.com for more info!
