How does fake adderall compare to real adderall?

Seen a lot of people selling home made pills recently thats usually along the lines of 30% amphetamine sulphate and 70% dextroamphetamine tartrate or something. Which isnt that different to normal adderall but it is significant, ive also seen other slight variations to that mix in other adderall listings.

So my main question is what even is the psychological difference between the two in terms of effects?
