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