Adderall and Mydayis[ten] are trade names for a mixture drug named mixed amphetamine salts ("MAS" items) containing four salts of amphetamine. The mixture is composed of equivalent pieces racemic amphetamine and dextroamphetamine, which creates a (3:one) ratio (by excess weight) amongst dextroamphetamine and levoamphetamine, the two enantiomers of amphetamine. https://pillspulse.com/product-category/adderall/
