This is very frustrating, Most Chinese suppliers sell such cathinone precursor powder in brown color, and other users tell me that it is white crystalline powder, because according to them the brown color is due to impurities, some real expert who knows can Answer my question? I don't know who to believe anymore because each one says a different thing.

Did you get any clarity in the end? From this topic its still not clear to me
I see everybody selling beige like powder and using this, this is "white" ? or is "white" really as white as snow?
Brown I have not seen unless people mean beige but brown is more like chocolate right?

Hope you can help me thanks
