The first step is to test the pill for the presence of a methylenedioxy substance (MDMA, MDA, MDEA). The most common regeants for this test are the marquis, mecke, and mandelin. All will test for MDxx, but each test also for various other substances so for best results, test separately with all 3 of these regeants. Then there are follow up test to test for primary and secondary amines.

Start by scraping a small flake of the pill (much smaller than this period ".") onto a bright white surface that is shaped so that fluid will not run off. SWIM has used white plastic spoons and the lid that comes with an EZtest kit for this purpose. It must be white to analyze result most clearly. Carefully pour one drop of either marquis, mecke, or mandelin onto the particles. Depending on which regeant used and the contents of the pill a color change will occur. Now you have to learn to analyze the results. The test kit should have come with a color chart for the substances it will test for, if not, reference a chart online for the corresponding kit. A good way to understand the chart is to view it as a timeline from left to right. Don't just think of it as the result turning some color in that chart. So for the marquis and mandelin as soon as the fluid touches the pill residue, it should immediately turn the fluid to a color towards the left of the MDMA, MDA, MDEA chart (a bright purple) and then continue to change color working towards the right of the chart, more of a dark purple or black. With the mecke regeant, this will be a bright green, as indicated to the left of the chart, to a dark blue or black color to the right of the chart. The color changing to black for all 3 should take 10-20 seconds or so from the original color. If the pill did not pass these tests, then it either does not contain MDxx or has a significant higher amount of an adulterant and the pill is no good and there is no reason to test further unless you are just curious of course. Sometimes the colors of the test may turn colors from more than one chart. For example, the very first pill SWIM ever tested with a marquis immediately turned orange, and then turned purple. Consider this test a failure for purity. Try using all three of these regeants on separate scrapings for cross examination purposes. All three tests should pass, not just one or two of them otherwise there may be a problem with the pill.

A positive test result for part one only indicates the presence of MDxx, this does not mean the pill is good, only that it is worth further examination or analysis. Part two will test for a primary amine or secondary amine. Start with simon's regeant and the buffer regeant. On a new pill scraping, pour one drop of simon's and two drops of buffer and analyze results. It should quickly turn blue, then darken over 10-20 seconds. If the pill passes this test and it already passed an MDxx test, then the pill is definitely either MDMA or MDEA. If it does not pass this portion or to further examine, test with robadope on a new scraping using same technique; one drop robadope with two drops of buffer. If it turns red, then it containes a primary amine, that could include MDA, but also PMA and possible others. If this happens, do not consume the pill unless laboratory testing is done to confirm that there is not PMA in the pill.

Keep in mind, analyzing results correctly does take some experience. Just because the pill passes all these tests doesn't mean it's a strong pill, it could still be very weak. Try to always be consistant, such as using the exact same amount of scraping, only one drop of reagents other than buffer and make sure that the room temperature and the temperature of the reagent itself are consistent. With this and some experience it is somewhat possible to determine relative strength of a pill (Notice I said relative strength, not quantity). This is much more advanced though. Try experimenting with a few different pills using the smallest scrapings possible and you many notice that even with positive MDxx results, there may be differences in reactions from one pill to the next. Example, using a mecke reagent on similar sized scrapings of different pills you may notice that pill 1 immediately turned all the reagent fluid green and quickly darkened. Pill 2 however slowly turned the reagent green over the residue and took a long time for the green to expand throughout the fluid and then took a much longer time to darken. Assuming the same size scrapings and drops of reagent used, we can say pill 1 was probably significantly stronger and pill 2 probably is very weak. Manufactures will sometimes put just enough MDxx in a pill to cause a positive on a regeant, that doesn't mean its worth taking.

Post Quality Evaluations:
A very good start...

Also try testing different areas of the pill. One time SWIM tested a pill and had no reaction, he then scraped off another area of the same pill and it was positive!

Re: How to use reagent kits to test ecstasy for purity?

Really quick one; say for instance a batch of supposed MDMA is cut with speed, 50/50 (or even 30/70 for examples sake) what is more likely to show up - or how will the marquis test act? Will it go brown then black or a lighter purple?

From SWIM's previous experience with this, the reaction will turn orange at first and then eventually turn purple, then black. Two different pills have had this result for SWIM indicating that either the marquis reacts first to (meth)amphetamine and second to MDMA or there was a higher amount of (meth)amphetamine than MDMA present. The reaction should not turn a mix of both purple and orange (brown), but a sequence of reactions.

Thanks for the responce, Swim thinks this is good information to have in the sticky becuase substances are (unfortunately) cut quite often.
