4-Fluoro-4-methylaminorex (4F-4-MAR) is a stimulant drug of the 2-amino-5-aryloxazoline class that was first synthesized in 1960 by McNeil Laboratories

4F-MAR has effects comparable to methamphetamine but with a longer duration.

It produces long-lasting effects, generally up to 16 hours in duration if taken orally and up to 12 hours if smoked or insufflated. Large doses have been reported anecdotally to last up to 36 hours. The effects are stimulant in nature, producing euphoria, increased attention, and increased cognition. Anecdotally, it has been reported to produce effects similar to nootropics. However, there is no research to support the claim that it is different or more effective than other psychostimulants in this respect. Moreover, 4f-mar

does not have the established safety profile of widely used clinical psychostimulants such as methylphenidate

This product is intended for laboratory research purposes only and are not to be used for any other purposes.
