Adderall and Mydayis[ten] are trade names for a combination drug called combined amphetamine salts ("MAS" products) containing four salts of amphetamine. The combination is composed of equivalent parts racemic amphetamine and dextroamphetamine, which produces a (three:one) ratio (by body weight) amongst dextroamphetamine and levoamphetamine, the two enantiomers of amphetamine. https://pillspulse.com/product-category/adderall/
