Disclaimer: I received a sample as part of my JackedPack to review for free. As always, all opinions are my own.
I received a sample of Maxler NRG Max in Blue Raspberry flavor. This was horrid, it didn't mix up well. Sediment was floating in the water, and it turned a sick greenish color that reminded me of swamp water. It tasted like trying to drink a blue raspberry warhead, yeah it was that sour. I couldn't even choke it down enough to tell you if it works or has any side effect. It was just gross!
