4-EAR or 4-Ethylaminorex is the ethyl analog of 4-MAR. Not a lot of information is available about it except that it may be more potent than 4-MAR. Like 4-MAR, it is likely similar to stimulants like methamphetamine, amphetamine, and cocaine producing effects of euphoria and stimulation and side effects such as hypertension and tachycardia.
