My understanding is much of the difference between name brand and generics is the excipients used, as they effect drug delivery. Not all generics will use the same and the name brands generally have patents on the ones they use. For psychoactive compounds this can make a considerable difference in how the drug functions for an individual. YSK that lisdexaphetamine has come off patent this year, and is purely a dextroamphetamine prodrug. It might provide more consistent results compared to adderall even in a generic formulation.
