Mephentermine

Mephentermine was originally approved by the FDA in 1951 as a vasopressor (used to increase blood pressure) and a nasal decongestant. It’s banned in the United States, but still used in other countries. It is structurally similar to methamphetamine. It’s prohibited by the World Anti-Doping Agency – used by young athletes for its stimulant effect and improved physical performance.
