I don't think it would be too much imo if you stuck btw 8 and 16. I have taken 16 along with one scoop of Craze by DS. However I switched a couple months ago to PNI Prodigy, and that stuff doesn't need a damn thing to go with it. I have 8 guys on it at the gym I go to. PNI Prodigy (25 Servings)
Best thing you can do is take one 8mg with it and see how you respond.
