so i was looking up on adderall and dexedrine. it says that dexedrine is dextroamphetamine. it says that adderall is dextroamphetamine + racemic-amphetamine. i looked up racemic and saw something about opposite isomers, but im not very good at chemistry and didnt really understand.

can somebody explain to me what a racemic-amphetamine is and why adderall is a mix of that and dex. also, what does the racemic-amp do differently in your body than just plain dextroamphetamine? thanks

adderall is

1/4 Dextroamphetamine Saccharate
1/4 Dextroamphetamine Sulfate
1/4 racemic d/l Amphetamine Aspartate Monohydrate
1/4 racemic d/l Amphetamine Sulfate

dexedrin is

Dextroamphetamine Sulfate

a racemic mixture contains the same ratio of levo/dextro enantiomers for non-superimposable molecules. (mirror images, like, say, your right and left hands.)

therefore, you could say it contains

2/8 Dextroamphetamine Saccharate
3/8 Dextroamphetamine Sulfate
1/8 Dextroamphetamine Aspartate Monohydrate
1/8 Levoamphetamine Aspartate Monohydrate
1/8 Levoamphetamine Sulfate

the dextro enantiomer is the stronger isomer -

i.e. levo-methamphetamine is an otc med that produces slight stimulant effects on par with caffeine.

the purpose of the racemic mixture is, according to the company, to allow for a smoother come up and come down, as the different salts are metabolized at different rates.

did that cover it?

a lot of it. im still a little confused with the above ^. Could you say that adderall is liked watered down dexedrine because it has some OTC parts to it?

only levomethamphetamine is otc,

however, yes, enantiopure dextroamphetamine is more 'powerful' than a racemic amphetamine mixture.

i.e. if you had all the components separated, it would be fairly pointless to take the levo isomer with the dextro.

well, not pointless, but the levo is much weaker than the dextro.

so, yeah, call it watered down if you like.

What? No, what he is saying is that in theory, Adderall is supposed to be exactly like Dexedrine but the added racemic amphetamines are meant to ease the come down rather than just letting you crash.

well, 6/8 dextro and 2/8 levo

so not exactly the same

and any ease of comedown would mostly be because of the different salts...

it is not supposed to be the same. adderal has less d-amp in it. u want d-amp. thus take a pill that has more d-amp in it....dexadrine TUDA!
