How do you make adderral?

You don't.

Adderall is a controlled substance that you should only get from a doctor or pharmacist if you need it for ADHD. Since you are asking how to make it, I assume that you do not have a legitimate need or legal use for it and are probably looking to sell it as a super-concentration device in schools. Let me tell you right now: don't do it. Not only will you go to jail for possession of a controlled substance, you could kill someone. If you take Adderall when you don't need it, there are many harmful side effects. You could also get people expelled or put in jail with you.

You've been warned.
