> Just general info thanks.hello there, chemist here....adderall is a racemate comprised of l-amphetamine and d-amphetamine sulfate salts: these compounds are not isomers. they are enantiomers. also, the ratio of d-amphetamine to l-amphetamine is 3:1 in adderall, not 1:3 as noted above. for immediate-release, expect peak plasma concntrations of both compounds between 3 and 5 hours. for the extended release, 5-9 hours for t_{max}. all the best, chemist
