prefer dexedrine to adderal,altho if the dose is high enough for adderall i would pick the IR just because it is more of a recreational type drug than the XR version,in my opnion.Again this depends on the dosage..I like the rare Dexedrine syrup,5mg per 5ml(teaspoon). I knew a dude that had some of this Dexedrine syrup his doctor gave him for some reason,and it was great,althouhg it still was not instant hitting you,it was quicker than digesting a pill or capsule with "pellets" of dexedrine of a dexedrine tablet...We drank about a shot glass each of the Dexedrine syrup,which is 30ml or 6 teaspoons which=30mg Dexedrine of the syrup and withing 30 minutes it was kicking in pretty good and after an hour we were both fully amped up...lol..gimme that Dexedrine syrup,it was flavored although i don't remember what flavor it was,it was tasty sruff,and it got you amped and lasted a good 8 to 10 hours..
