### ⭐⭐⭐⭐⭐ Taste good..
*by U***E on August 30, 2024*

Mix well, and it is easy to dissolve with water and tastes good. My appetite has been suppressed lately, so if it stays this way, I know I will lose weight. I haven't had any stomach problems while taking these. I'm going to continue using it until I complete the container. The product smells sweet.

### ⭐⭐⭐⭐⭐ Good for beginners
*by V***5 on April 26, 2026*

Good pump. Safe for starters. My son is 16 and really likes this.

### ⭐ If you like chlorine and sugar water this is the product for you
*by A***R on February 1, 2026*

Flavor: Caribbean Punch tastes like sugar water. You can’t taste any specific fruit or flavor. Ingredients: I saw this has stevia and bought it. I didn’t see it also contains sucrolose (which is made of 3 chlorine atoms…..chlorine and the gut microbiome do not mix well. Also, research insulin resistance and sucrolose. Will not buy again.
