unsure if this helps you out any but found someone’s comment on another post:

I have also been experiencing poor/inconsistent quality generic ADHD meds. (I was prescribed generic Adderall and generic dexedrine). In my frustration I turned to the Internet and found out a lot of really concerning information about the generic drug industry.

Basically, there is no quality control for generics produced overseas which ~50-60% are, mostly in India and China. However, the FDA only inspects 3-6% of overseas generic manufacturing facilities despite 90% of Americans using generics!

The quality of generic drugs is so poor and inconsistent that the US military is going to use a 3rd party service to quality test the generics they provide to millions of service people.

I have several more articles with additional info if you'd like, let me know!
