Adderall and Mydayis[ten] are trade names for a combination drug called blended amphetamine salts ("MAS" goods) made up of 4 salts of amphetamine. The mixture is composed of equal parts racemic amphetamine and dextroamphetamine, which provides a (3:1) ratio (by fat) among dextroamphetamine and levoamphetamine, the two enantiomers of amphetamine.
