Formetorex belongs to the group of N-acetylated amphetamine derivatives, which arguably acts as a so-called "pro drug", i.e. an amphetamine precursor that is converted to amphetamine in the body. This class can potentially exhibit acute or long-term toxic effects.
Formetorex is known to have an appetite suppressant and mild stimulant effect, but this is much less than amphetamine.
Little is known about risks of the substance, but it may have potential acute or long-term toxic effects.
Each synthesis impurity represents an unknown health risk: the properties hazardous to health have never been scientifically studied and are therefore difficult to estimate. The more different synthesis impurities are contained in a sample, the greater the probability that an impurity with a high adverse health effect is among them. Even a small amount of such an impurity can be harmful. In addition, synthetic impurities are an indication of improper manufacturing/purification. It is also important to add that regular use of amphetamine with synthetic impurities poses a higher health risk than one-time use.
