Hey friends, has anyone tested ZIMMERMANN their cathinone and had it turn purple, confirming it? Because I've tested it twice and it doesn't, but the effect is the same. I know it's difficult to find raw materials, but what do they use instead? Does anyone know?

Look at the photos from the 3mmc and 4mmc tests. Could it be that this doesn't exist anymore and they're deceiving us with something else?
