Fasoracetam with Adderall?

I take adderal 20mg IR daily 3 times for focus prescribed for adhd.

I find that I still have issues with a little anxiety and memory, from what I read, fasoracetam can help with that.

Is this a safe stack? Also does fasoracetam do anything with heartrate or blood pressure? Mines a little on the high side on adderall.
