About 5-MMPA Powder

5-Methylmethiopropamine (5-MMPA), also known as mephedrene, is a stimulant drug that serves as a ring-substituted derivative of methiopropamine. Unlike substituted cathinones such as mephedrone, 5-MMPA does not possess a ketone group at the β position of the aliphatic side chain, making it more closely resemble substituted amphetamines. This compound has been sold as a designer drug and was first identified in Germany in June 2020.
