Tastes like juice!!

This was my first experience with clear protein. I was pleasantly surprised how tasty it was! It's sweet, but not too sweet for my boring water drinking self lol
It'll definitely be a staple for me this summer!

I Prefer pre mixed Protein Water

Tastes great, but honestly I prefer the pre mixed protein water. I’d rather pay for the convenience of buying the 12 pack bottles. Sorry…
