bring it to a lab and have it analyzed there. In holland they will give quantitative data about it (how many mg in the pill.) ecstasydata.org will only give ratios. ( 1:1 mdma, or 3:1 speed:mdma)
^ It can often have to do with the other tablet constituents. Particular binders and excipients may effectively slow the reaction. Some people therefore prefer to crush or grind their sample to a powder before testing.
yeah i thought this was the case, that when u droped the liquid, the speed of it changing was the strength.
i found this to be false, when i tested one last weekend that went black on contact. thinking it would be heaps strong, i was dissapointed.
I've tested what I believe to be pure MDMA and the test result speed was very fast with bubbles and a whisp of smoke whereas pills have a much slower reaction (no or few bubbles and never seem a wisp of smoke with pills). That said I've tested pills which had a fast reaction and after consumption they were far less potent than other pills with a slow reaction. It's seems EZ test offers only a very rough guide.
that is why we do not make any claims to proving purity! the reaction should be quick, but faster and slower does not mean more pure. all I can say about it is that it must be the binders that slow the reaction down. but that does not mean there is little mdma present!
