My vote is some pipe that makes marquis orange for whatever reason, because I left one I tested in a drawer for a week and it turned gooey and stuck to the fabric liner... I hear pipes absorb humidity and get moldy / (or even gooey) in some cases...
This is the test results I have gotten from every fake pisces I ever tested, which is quite a few now. I got the same results last spring from some red-orange / yellow / blue / mauve pisces, then I recently found some identical to
these that came with the same exact looking & testing yellow & red-orange from last year, except these did not test like DXM at all; they tested exactly the same as the others... Same strength of the test result also, although it was considerably thicker (~50% thicker), which leads me to believe whatever the fuck chemical it is, the green one has a higher dose.
It's strange Edata received one that tested for DXM. Sometimes I wonder about the lab results... Factors like contamination, or did the "tester" just take a picture and "dispose" (eat) the pill and guess the chem, then keep the $40 (cash) lab fee? I never, never tested a pisces that tested for DXM. Only MDMA, MDMA + Meth, & unknown (the unknowns all tested the same as described in OP). Most pisces I tested have been clean. And it's pretty much impossible to find any other stamps in this area besides the pumas that have just recently started circulating (same presser), so you can kind of guess how many pisces I've tested over the years...
