Set of Key Nutrients Electrolytes Powder in Blue Raspberry and Peach Mango flavors. Perfect for hydration. The blue raspberry is brand new. $40 on Amazon. The peach/ mango is not brand new. I used it at the most 7 times. You can see how much is left in the pictures. I loved the taste of it but then I got the stomach flu and tried to drink this while I was sick to keep my hydration up. It started to taste really weird during my sickness and I still taste that weirdness. My sickness ruined it for me.
