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.

Esto es muy frustrante, la mayoría de los proveedores chinos venden ese polvo precursor de catinona en color marrón, y otros usuarios me dicen que es un polvo cristalino blanco, porque según ellos el color marrón se debe a las impurezas, algún verdadero experto que sepa puede responder mi pregunta. ? Ya no se a quien creer porque cada uno dice una cosa diferente.

chemistry.mobDid 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
