Where is @Jojo when brain is involved 
On a serious note, generally it’s more advantageous to run each more times except Plasma Brain and stimulating ones (especially not Acetylcholine). SuperHuman Genius 3-4x, Enhanced Hemisphere Connectivity after it and up to 10x. Brain Dancer 2x, also preferably adding MState Gold and Silver and start.
Plasma Brain is fine at end and to loop, but not optimal. Enpp6 enzyme couple of times before Plasma Brain.
In general, did you take a look at Big results - 2 years of using (Brain Stack) - #175 by DR_MANHATTAN and rest of this thread?
