A sample sold as" in Austin, TX sent to that tested as N-Ethylpentylone. This has been circulating as adulterated since we found this stuff in 2016 in NYC. If it looks like the reagent tests bottom left, and you're expecting a substance or an experience like MDMA, Methylone, or Ethylone–you will be extremely disappointed. I can almost guarantee you're dealing with bk-EBDP and no other (based on drug trends and drug bans) at this point, and the results are undesirable for avid users of the aforementioned substances.
Just a reminder, that I do not do these lab tests. Send your samples to escstasydata.org. If you are not local to the NYC area, I can/will not reagent test your substances. These posts are for educational purposes, only
