Question Easiest way to separate the 2 amphetamine isomers

[VamonosPest2]

I plan to use both the isomers to try to come up with a better and more efficient way to treat my ADD.

Questions
-are there any easier alternatives than sulfuric acid? it is pretty hard to come by in my area, especially concentrated sulfuric acid.
-which type of tartaric acid do i need to buy?

Feel free to share links or if you have any other tips for this procedure in general.

If Sulfuric acid is to hard to come by for you, optical separation will be a real challenge.

For inspiration se eks US patent nr 3028430

You coud use a number of acids for your protonater, your result would just be a different salt not amphetamine sulphate. Theres a thread with i think 13 amphetamine salts and testing which ones you can smoke. There are other acids you can use to resolve also, a chiral lewis acid
