Molly is nearly pure MDMA, be careful for test chems passed off as molly.
good molly i have had is many different colors, cloudy white, cloudy pink, amber, amber and dark like concrete was the best i have ever done. mine blowing.
used to handle lbs of molly, use it sparingly, i have done molly for 3 weeks straight, there is a tolerance like shrooms, you got to do it weekly if not bi weekly or monthly
