    this is the best meal bar we have ever used. They are off the charts great tasting and filling.

    Best tasting bar for the dollar

    I was introduced to this supplement bar by a friend who goes all out trying to find a bar that not only is delicious it has good ingredients. I have gone through many bar, almost the entire gambit of protein bars and this is the one that transcends from boring and heavy protein tasting to rich and sweet! It’s not so heavy that you don’t want to finish it and just crunchy and sweet enough to fill that sweet tooth void for those trying to shred! I hope sinisterlabs continues such awesome supplements for all aspects of life in the future.
