BCAA² - Clinically Dosed All-in-One Intra-Workout BCAAs - Nitric Oxide Booster, Endurance Formula for Hydration, Strength and Focus - No Artificial Flavors or Coloring - Citrus Squeeze

Seems to fit the bill but the taste...oh the taste. It's pretty rough. Yes, it is a little bit of a citrus taste but there is a very strong almost bitter/sour aftertaste which I was not prepared for. If you mix it with some Mio it's better - that helps cover the taste. Somewhat. It seems to be helpful for maintaining stamina during my workouts - I've only used it a few times so far. Because of the aftertaste unless this had mad super powers I would not buy again.
