Klean Athlete Klean Essential Aminos + HMB, Orange Cream, 9.7 Ounces

Amazon reviewers say this product generally works well for its intended purpose, with several customers describing it as effective and worth using. The most common complaint is the flavor, especially the orange cream taste, which some reviewers call terrible or overly artificial.

On the brand’s own product page, customers also report positive experiences, saying it helps with post-workout recovery and that they can feel the benefits. A few shoppers note they prefer mixing it with protein or another drink to make the taste more tolerable.

On YouTube, the specific product appears in review-style videos that describe the orange flavor as not great, but still call the ingredients and overall formula strong. Those videos frame it as a solid supplement for athletes who care more about formulation and certification than taste.

Overall, the pattern across Amazon and YouTube is consistent: strong satisfaction with performance, mixed-to-poor reactions to flavor, and occasional comments that it is best used mixed with something else.
