Question about 'new' test kit

What reagent can distinguish between the various MDxx compounds?
It was rumored that by adding methanol you could 'time' the reaction and tell if it was MDMA, MDEA or MDA .. but after extensive testing this was shown to be false ..

This is still an issue.
The E-Z Test does have methanol in it but the difference is really too small to be sure that what you are testing is mdma, mda or mdxx (whatever).
Also, what if there is mdma and mda in it (or mdma and mdea or any combination), you might be left with the wrong conclusion.
That is why we took it out, we don't want to pretend that we can give you certainty.
ONLY a lab test can give certainty !
