Tested first with Marquis, straight to black. Then tested another sample with Folin A/B, and it went to salmon/pink (MDMA). Here's a shitty picture.

Also here's a picture of some of the product.

My mistake was applying the Folin test on the sample that was already tested with the Marquis. I guess I got the whole "secondary testing" idea wrong lol. Instructions say to use the Folin test only after first testing with Marquis, I took it literally. It must be tested with Marquis first in order to identify the product, as some of the Folin reactions for different substances look very similar.
Also here's a labtest result posted not too long ago:
I just Marquis/Mecke/Mandelin/SimonsA-B on both Stealthbomber and Lostheaven's most recent batches (actually, again, spurred by your claim that SB was MDA).
They both reacted exactly the same shade, tint, speed, etc, under Marquis, Mecke, and Mandelin (there are those that claim they can tell MDXX based on exactly how it changes to black).
Regardless, Simon's A/B went to Cobalt dark blue right away.
It wouldn't be far removed to think they are the same source (LH smells stronger, slightly different, but LH also crushes his shit up so that's probably why). Maybe same cook, different (or same?) packager/cutter/purifier/extractor.
These guys are probably mid level dealers where they are from.
As for MDA costing more, I have actually run into street sources that get MDA for cheaper than what the street value of 'bulk' MDMA is (they have both presses and crystal, and have always represented their product as MDA too - they were always MDA > MDMA bandwagon folk). I have seen street prices for MDA lower than the DNM in a shithole, pretty sure in a well connected region like NYC it wouldn't be hard to find (much less an actual distribution or manufacturing hub like in Europe or Canada).
The DNM is a small, small world, it's a very small pond with mostly small fish.
