Took 2 packets upon waking on an empty stomach. Flavor is candy green apple. Amazing taste!. I felt a little bit of energy for about 15-20 minutes after I took the packets. After that nothing...It does mix pretty well though. All it took was few shakes in a shaker cup and it was dissolved. I took it pre-weights, maybe this stuff would be better pre cardio, but I didn't notice any endurance effects either so I guess it just doesn't work to well for me. Just being honest here, hope it works well for others. Thank you to ANS for letting me try this out.
