Adderall and Mydayis[ten] are trade names for a mix drug named combined amphetamine salts ("MAS" products) containing four salts of amphetamine. The combination is made up of equal pieces racemic amphetamine and dextroamphetamine, which generates a (3:1) ratio (by pounds) between dextroamphetamine and levoamphetamine, the two enantiomers of amphetamine. https://pillspulse.com/product-category/adderall/
