text:  My friends that have played professional sports, I understand B12 is fantastic and high dosage as well as vitamin C. These are things that really help you focus and feel energized and get through things. I can tell you my substance of choice to abuse for energy, caffeine. Love that stuff. And not in the form of like those energy drinks and whatnot, but in the form of cafe, cafecito. Like Cafe Bustelo is my favorite. They're not a sponsor. They should be, but they're not.
