for the energy one, the ingredient list is water, fuctose, energy blend, sucrose...first thing that confused me is why they'd bother putting anything proprietary in the drink if they're going to include pills to take on the side. Secondly I really don't like suagar additives in my health conscious products. All in all it's gatorade with some supplements on the side. So, I would use it the same way I would a protein bar, which is basically as a conveniently packaged but less than ideal subsitute for supplements I keep at home. The price would have to be very reasonable for me to consider buying any. Protein bars are expensive as hell, but there's just no getting around the fact that you need protein, unlike stimulants, enzymes, or even additional vitamins beyond what's already in your chosen daily multi.
