Goddamnit, well just did a side by side with the Liebermann hoping to replicate my results and have a better idea on the color changes. And they all turned a maroon over time this time.... Fuck me im sorry guys. To varying extents I suppose and at varying times but not different enough to be positive.
G_Chem, thanks for doing all this work and posting your results! Very few of us have access to so many samples AND the knowledge to rate them as magic or not.
I was wondering if you could test your samples with MDMA purity test from EZTest. I had decent results with it, esp for pills near 50% MDMA content. It's harder to tell 80% from 90% purity based on color saturation. If I you have extra sample and an extra test, I guess you can dump 3x the amount (60mg) into the test tube to see what this test shows for 100% purity, but I don't have that much.
It'd be great if we found that magic simply correlates with purity more often than not. A while back Hilo had a meh sample that MS tested at 82% and a magic one that tested at 91 or something close. This thread decided that 82 and 91 were too close to cause that much difference in effect. But on the other hand, 82% has 2x more impurities, so maybe there is some purity threshold where for most users you really need to have >90% purity to approach the magic zone. And Indigo's sample, which was ok/meh, also tested at only 80.
There is another interesting factor for this test for high purity samples, which I think fits neatly with your color id angle. Most charts and photos show only shades of brown. But one DNM listing I saw advertised very pure product and showed a picture of this exact test with a very clear shade of purple with bright orange on top. If I remember correctly, that orange looked exactly like the 15-minute mark on the color chart. But the picture of actual test tubes from testkitplus shows only shades of brown. Here are some pics of the test results. I'd be very curious to see if any of your samples go through the purple/orange stage at 15-30 minutes.
MDMA - Purity and Mandelin
Hi guys, Got a new batch of MDMA crystal and ran it through the EZ test kit purity test and Mandelin test, looks ok to me on the purity test but the Mandelin looks a bit iffy. Looking for a second opinion before I bin it Purity test after 45 minutes Mandelin test to show tint Mandelin solid...
