Vinpo and RPM will have some synergism, especially as far as psycho-stimulation and PDE inhibition (vinpo will contribute to great pumps and blood flow)- and they will also have a synergistic effect as far as focus
Gingko and RPM will have synergism- as far as focus- should be fairly intense
Tyrosine is strongly synergistic w/ RPM- chocamine already contains tyrosine- but a little more will enhance focus even further
Bacopa and RPM are synergistic for focus and concentration as well
Huperzine A- VERY, VERY synergistic with Icariiin- both inhibit ACHE- and the combo of the two will result in some phenomenal muscle contractions and mind-muscle connection
gotta run- will get to the rest later...
