Second batch of this stuff
I love the flavor and it makes a noticeable difference for me in my workout. I just turned 50 and was struggling to finish my modest workout (I would feel exhausted after less than 30 minutes).  I don't take anything else (i.e. no pre-workout or special supplements other than a multi-vitamin). Also, I workout after work in the evening and I am not an athlete of any kind (i.e. desk jockey).
