It's so prevalent on Reddit that every time I've mentioned it often being NEP, complete with proof, it's scoffed at. The crystals are far better in my experience, and it has only been powers that have come back testing as NEP or other cathinones, so I'm saving a bit of my current powered "N-Ethyl-Heedrone" to post off to Energy Control in Spain. I did a very rushed, kitchen-type acetone wash of the stuff, but either it's >90% pure something, or it was just my shit technique. Hoping to do it proper within the coming week.
Home test hits won't help, that's why I'm paying for the full GC/MS and NMR report
