Yeah I do agree with still_crazy in terms of using an amphetamine, on its own, for depression.

Adderall is mainly used for narcolepsy and ADHD- so those uses mentioned above are off-label.

As it is a stimulant, Adderall does suppress appetite and help with weight loss (as Ritalin does too) but yeah, not really used before things like phentermine etc.

Desoxyn is very rarely used as it is methamphetamine and quite easily abused.

For depression, in conjunction with antidepressants- lithium or lamotrigine (Lamictal) and neuroleptics (antipsychotics) such as Seroquel, Abilify or Zyprexa are effective.

*Note that some antidepressants may cause weight gain but the AD/AP combination is usually reserved for treatment resistant depression.
