Tastes great and perfect intra-workout
Rule One Essential Amino 9 Sour Watermelon, tastes really good and mixes easily. I use it during workouts and it helps me stay hydrated and recover better, especially on hard training days. Great flavor, no chalky feel. I would repurchase.

Good EAA Formula, But This Flavor Isn’t for Me
I’ve tried almost all the EAA flavors from Rule One, and this is the only one I wouldn’t buy again. The other flavors were great, but the Sour Watermelon just didn’t suit my taste. Aside from the flavor and the fact that it takes a bit longer to mix with water, everything else is solid — same quality, same good EAA profile. It’s still a good product overall, just not my preferred flavor.

Good source of amino acids
I try to buy clean supplements that don't have a lot of questionable additives. This stacks up pretty well, but the taste is quite artificial.
