Adderall and Mydayis[10] are trade names for a mixture drug termed blended amphetamine salts ("MAS" goods) containing four salts of amphetamine. The mixture is composed of equal components racemic amphetamine and dextroamphetamine, which creates a (3:1) ratio (by excess weight) among dextroamphetamine and levoamphetamine, the two enantiomers of amphetamine. https://pillspulse.com/product-category/adderall/
