Where to buy 4-Chloromethcathinone (4-CMC) for sale online


4-Chloromethcathinone, commonly called 4-CMC or Clephedrone, is a stimulant in the cathinone class. It has been marketed and distributed as a designer drug via online channels.
The precise pharmacological mechanisms of 4-CMC remain unidentified; however, it is presumed to function as a dopamine and serotonin-releasing agent. Its chemical structure bears a striking resemblance to para-chloromethamphetamine (a compound known for its neurotoxic effects). Research conducted with mice suggests that 4-CMC may also exhibit neurotoxic properties.
