Dexedrine is pure dextro.
Adderall is a mix of dextro and levo (ie mixed amphetamine salts)
My experience s with Speed/ dl-Amphetamine, which i also used in small doses.
As study aid, relevant as on a big dose i wouldn t even be able to concentrate.
Small doses work oral probably the best, but i snorted it.
And it always was a delicate balance to much and it becomes recreational.
Has effects on your night of rest. Dextro-Amphetamine oral in those doses.
Has no resemblance to racemic, just did what it was ment for without side effects.
[except dry mouth at the start only and that was it no other side effect noted]
Did extract the dextro-Amphetamine once, so I could snort it and get spun.
Extraction went well, but it never became re creative like Speed.
Even not up my bunghole. as that is where the last went. Snorting did nothing,
for me. But YMMV, lots of people find dextro also fiending and addicting.
Adderal is in between Speed and Dextro-Amphetamine.
And i have no clue how it feel s, but assume the 25 % l-,
does make it feel Speed like. Someone who took all 3,
might shine some light on it.
