Anyone ever use FRS?

Saw it at the Vitamin Shoppe....just looking for thoughts or experiences?

YUP... I drink 1 -2 everyday... Love them! Wild Berry is my Fav... When I ran the 100 mile trail run last month, I drank one at the beginning of each loop. They taste pretty good, 25 Cals for the whole can and "Healthy Energy" as the can says... I'm a fan

I drink them all the time.  Kind of pricy in the can, but convenient. the concentrate is good too, and you get more value.  As for noticing any difference, not really, They taste pretty good, and they are non carbinated unlike a lot of the energy drinks.
