What is the difference in ingredients between the orange round E404 Adderall and orange oblong b974?

The E404 flat circle tablets are a weaker form , do not last as long, and make you tired and cause bad headaches . Do not switch to those if your body is already use to the oval peach colored b974 pills.

There is no difference with the exception of inert fillers, colorings and packaging. Both are a combination of amphetamine and dextroamphetamine.
