turned instanly jet black, is it DXM or MDMA i'm unsure as it is my first time testin and many say black is good but marquis indicator says otherwise. it was a crystal MDMA look-a-like and taste -a-like (tiny nibble). Some experienced testers appreciated,
Thanks in advance.

Edit: Failed the photos, how do i upload them from my mac?

DXM - grey to black, releases a slight bit of smoke

Straight to black should be good as far as i know.

Thanks for the quick response! I'm optimistic about it. However, they really need to make the indicator's clearer, the DXM is signalled grey to black but the small research i conducted into the look etc of the chemical reveal its highly unlikely. So, i'm pretty certain this is MDMA but would like 100%.
