Adderall and Mydayis[10] are trade names for a mix drug called mixed amphetamine salts ("MAS" goods) containing four salts of amphetamine. The mixture is made up of equivalent parts racemic amphetamine and dextroamphetamine, which produces a (three:one) ratio (by pounds) involving dextroamphetamine and levoamphetamine, the two enantiomers of amphetamine. https://pillspulse.com/product-category/adderall/
