ADDBack is a supplement designed for Amphetamine and ADD and ADHD medication users.  ADDBack may help replenish re-uptake inhibitor's from the increased activity from neurotransmitters, dopamine and nor-epinephrine that have been depleted from the use of these drugs.  ADDBack was designed with these people in mind to potentially alleviate the negative side effects, such as next day crash, fatigue and depression.  ADDBack may also help with Amphetamine drug tolerance.
