I actually have felt some effects if I take AmiNO Energy (Optimum Nutrition) right after I take A2 and Erase Pro. Strong enough that I wont do it again.
I backed off of that and have been fine. Currently taking Erase Pro (1cap) and A2 (2 caps) at 6:30am...holding off any caffeine stimulant until later in the day. Just took 1 OEP at 10 and feel fine.
Good to know...thank you
