Well, this is certainly late getting up here, but I did want to get it on the board since AI was so generous to send the samples out. Thanks!
I tried the pink lemonade flavor of and was very impressed. It tasted absolutely delicious; dead on to the pink lemonade my mother would make in summertime when we were kids (seriously, I haven't had pink lemonade in a long time and the taste shot me back to childhood. I love when sensory triggers remind me of things).
It was a very concentrated feeling during my workout and I didn't feel much on the stims. Granted, I was in dire need of a break from stims at the time and saved my other sample specifically for a time when my sensitivity was reset. I did sweat a lot, too. Numbers from the workout were pretty good.
All in all, I would certainly recommend this product based on what it seems to have the potential to do. And on a taste basis, I would rate it among the best tasting supplements out there. Seriously top notch.
