Happy with half price

This is a product that I regularly use and was happy to see it at Sam's at half the price I normally pay.

Great product with excellent flavor

Great Amino Acid Pre Workout. Grape is better but this one is delish.

Great Flavor - will repurchase

Very tasty. The watermelon flavor is artificial, and reminds me of hard candies. I haven't had it for a long time yet, so can't comment on how well it works for energy, but the hydration aspect is a bonus. Here's to hoping it works as well as it tastes.
