Is it possible to get prescribed ADHD medication such as adderall online as I have no primary doc?

Not from any site. Such medications are class 2 controlled substances monitored closely by the feds. Providing you with any of these without a proper physician/patient relationship,history & physical with supportive documentation of need can end the physicians career. They would risk loss of ever prescribing controlled meds in the future and loss of license. Your "need" is a poor reason for such a risk.
